Sentry Pet Products Reviews

Do not use this on your pets ever!!! This product kills fleas, ticks, and possibly your dog as well. I used it on my dog and she began shaking within an hour. Upon noticing this problem, we contacted our vet who stated that this product is very dangerous. Why hasn't anyone filed suit against this terrible company? Something needs to be done. How on Earth can these pet stores carry this extremely dangerous item?

I used Sentry Flea and Tick XFT 61 on my Pit mix. Within 12 hours he was stumbling up steps and running into things. Within 24 hours he was yelping out in pain just for moving a certain way, which is very odd. He then became very lethargic which is completely not him, and began to have muscle spasms in his sides. If you touched that spasmodic area the spasms worsened and he would flinch in pain. Took him to the vet and they told me to bathe him in Dawn dish soap several times as that is the only way to get the product off and gave him some pain medicine. A couple days later he was back to normal. My recommendation is not to buy any Sentry product. They should be pulled from the shelves. If you are reading this as a result of putting this so called treatment on your pet my best advice is Dawn dish soap baths and definitely consult with your veterinarian.

Sentry Pro Plus Flea and Tick Squeeze - I used this product as well but after reading all of these heart wrenching reviews, I feel lucky (somewhat) that our experience wasn't as severe as most. My 12lb Shih-Tzu started scratching more intensely than before the application about 2 hours after being applied. The next morning, my husband came upstairs and said that our little pooch had made a mess in his kennel and he was covered with his own stool. It broke my heart to see my baby that way. He continued to have severe diarrhea all that next day and us waking up that next morning to the same scenario. I was not too sure if maybe he hadn't gotten into something outside but I was still not ruling out that he was having a reaction to the "flea" medication.

I used this on my cat. Almost immediately she became very nervous. Over the course of a few hours we carefully monitored her and she was running in circles and very jittery. She was almost falling down at times. Then she started hiding and when trying to get her out of a hiding place we noticed she was foaming at the mouth. We immediately took her to the veterinary emergency room. At that point they could not even confirm if she was poisoned.

Oh my god, do not put this on your dog. I have a 28 pound loss also put this century pro on and he flipped out all night long. I washed it off two hours later but still I don't know what I'm going to do. I'll have to take him to the vet in the morning. I really want to give you a piece of my mind. Do not use this on your dogs at all. You will regret it. I'm going to the store and talk to the manager on Friday. Tomorrow's Thanksgiving so they're closed but I'm very very upset.

Our 15-year-old lab has had a hip problem for awhile but after having him on Rimadyl he was doing well. Suddenly he started falling and then he can't use his back legs. He can't walk or stand. We had him put down Saturday and now come across these reviews about Sentry. We had just used Sentry Fiproguard plus IGR on him the week he started to fall. I am more brokenhearted to find I caused his death from using this product! I am furious that this can even be on the market with all these complaints and adverse reactions. I will never use any of these chemicals of any sort on my pets! I have just had my beloved Cleve put down when it didn't have to be! I would like to sue them... and furious with PetSmart for carrying this in their store! Something needs to be done! This just WRONG!

Put this on my cat at 4 pm, and by midnight he was shaking and acting very strange. In the morning I found him hiding in the closet, unable to move. He couldn't drink, couldn't go to the bathroom, and was too anxious to be in daylight. It was applied as always between his shoulder blades on the back of his neck, but unlike Frontline and Advantage, this brand left him severely sick. One emergency vet visit later, and I came to find that the vet hadn't even HEARD of such ingredients. I immediately washed it off my poor cat and he was purring while I did this (he never purrs when there is water involved). Almost instantly after he was a new cat. You know why? Because the product was BURNING him, literally. And apparently I'm not the only one, as many of you have had your animals left with chemical burns. Shame on this disgusting company.

I have always given my pug Advantix or the generic Advantix on petmeds.com, but yesterday I gave him the less expensive Sentry flea meds for dogs of his weight. A few hours after putting the flea med on his neck, he began to scratch himself and the floor and pillows and walls uncontrollably. I literally started to watch him lose his mind before my eyes. He was convulsing and having mini-seizures while I had him lying on his back trying to relax him. His breathing was so fast I thought his heart would explode. He was panting like nothing I could never explain. So fast. So loud. I believed he was dying last night. We didn't sleep at all and he didn't sit still for more than half a second in a 15 hour period.

Daughter bought product for dog on Wednesday 11/4/15. Put medicine on our dog Wednesday night. My dog started running, jumping on sofa, rubbing body against sofa. Biting in the air, barking, biting her tail, whining uncontrollable thru the night. Gave her benadryl 2nd night. Today is 11/9/15 and my dog still is having reactions from the meds. I bathe her the 2nd night in the tub. She is still not acting herself. Took her for several walks and my poor baby is still not the same. I'm going to bathe her again tonight and give her Benadryl once more. It's been approx. 5 days, and she is still miserable. A lawsuit should be filed against this company for making this product.

I used this product on my dog a few times before. She always ran away once she saw it in my hand and acted restless and nervous. I thought it was just the smell. Last time she threw up but I also thought maybe it was something she ate. Last night, I used it on her and I went to bed to wake at 3 am to my dog throwing up and shaking and barely able to move with one side of her body frozen like she just had a seizure. I rushed her to the bathroom washed her very well to remove whatever is left on her. She was very scared, seemed lethargic and disoriented, didn't even want to eat bacon which is unusual. She is doing much better now, not throwing up but not back to the happy dog I know. She seems traumatized. I WILL BE THROWING THEM AWAY. PLEASE DO NOT USE THIS PRODUCT ON ANY ANIMAL.

I applied the flea and tick to both of my cats (2 years) and immediately regretted my decision. They both started to freak out and run around. My male cat started to drool uncontrollably for the rest of the day from licking the product. My female cat was fine until two days ago when I noticed her starting to go bald where the solution had been applied. The male has been starting to pull his fur out as well. They both have not been the same since I've used the product. When I called the number on the back of the box they were helpful but pretty much just brushed off my concerns. I would NEVER use this on my babies again!!

Applied Sentry drops as per the instructions. Within a few hours our perfectly healthy border collie became violently ill, repeatedly vomiting enormous amounts, then passing an enormous amount of liquid bloody diarrhea that was 60% blood--it looked like a murder scene. The dog and I were up all night and are headed to the vet. After reading all the reviews, I can't believe this product--POISON to many pets-- is still on the market. I've seen a number of people who intend to sue; I hope someone follows through because I believe this is the only way to motivate Sentry and chains like PetCo will change.

Before you consider using a product like this PLEASE read these reviews because they are not exaggerated in the least! I used this product on my German Shepherd/Husky mix and at first everything seemed normal, but like most of these other folks right at the 3 hour mark she started to act strangely: Disoriented, nervous, twitchy, just not like she usually acts. Then after an hour of pacing she started to lose her balance, kept shifting her weight, biting and looking at things that weren't there, and then ultimately convulsing violently. So much so that I had to brace her with all my strength every minute or so for four hours. I thought she was going to die. I washed the product off immediately. She would not drink water for two days afterward and did not come back to normal for three days.

Applied to six dogs of varying breeds, mixes and sizes. Three of six reacted negatively with agitation, scratching, nervous behavior. Of those 3, one, a corgi mix, reacted very strongly, with extreme restlessness, anxiety, scratching, biting at air, rubbing. Bathed with dish detergent and dosed with diphenhydramine per multiple online sources within 12 hours of application. She is improved greatly. DO NOT USE THIS PRODUCT - EXTREMELY UNSAFE. If I could give less than one star I would.

Sentry Pro XFT61 - My husband used this product on our dog. She is normally a very calm dog. Within a few hours she was running around the house scratching on the walls and floors. Normally when let out she sits right next to you and doesn't even need to be on a leash. She ran away twice. He gave her a bath shortly after this odd behavior started but it didn't make a difference. When I came home I gave her another bath, still no difference.

I bought Sentry Fiproguard Plus for dogs 89 lbs-132 lbs. for my 108 lbs. Pit Bull, due to recommendation of the sales woman at my local Tractor Supply. Not even 2 hours after I put this on him his skin became very irritated. He broke out in hives and it has been 3 days later and he still hasn't cleared up.

I move from Vegas to CA and on advice for prevent control on pets used Sentry Pro XFT. My dog in 30 min develop side effect, losing controlling back legs. Please remove this product from market. I contact manufacturer and didn't got call back. She is 2 year old PUG with perfect medical record, no parasite or allergy. She is in perfect health, and up with all vaccinations. I got reports from DOC office and now I need to run all test. My puppy its not ok after applying product p002776-2, purchasing at Petco in HB, CA. I don't have/receive bad credit card. Will confirm purchase in ZIP code 92649.

Sentry flea control in greyish color box. I put it on my cats, nothing happened. My poor cats are being eaten alive. They tell you "Give it time." Well I have two weeks and guess what, they're not dead. My poor baby has red swollen eyes due to scratching. This is the worst product out there next to Hartz. Now I can't put anything else on them for thirty days thanks to this Crappy product.

We treated our 6-month-old Rottweiler with Sentry a few days ago. She started scratching almost non-stop. Yesterday I noticed her fur was "wet" where we applied the medication. Thinking it was just greasy, I wasn't concerned. Today I took a closer look because she was still scratching. Her skin is red and oozing. She definitely has a reaction to this flea treatment. We washed her with Dawn which I'm going to do again. Tomorrow we will be going to the vet. These products should be taken off the market!

My cat came down with fleas so over the last few months I've been treating her. Frontline, Advantix, organic shampoos, etc. All of which I waited the appropriate amount of time in between before trying the next. None of them however were working. A friend recently treated their cat with Sentry and said it seemed to work so I gave it a try. Horrible idea!!! I put it on before work and when I came home my poor cat was bald and covered in hives. It's late at night so I have to wait until tomorrow to see a vet. I bathed her with Dawn dish soap to remove the horrible chemicals. She seems to be doing better. Do every animal a favor, don't use this brand.

My husband purchased both collars at our weekly trip to Petsmart!!!! After this incidents we will surely think twice.. Tinkerbell had never had a flea. And putting the collar on it wasn't 24 hours I noticed her left ear as red as a tomato. Took her to the Vet. First we took the collar off her. Went to feed to got ear cleanse and powder with antibiotics in it. We used the powder on our horse but never thought about our dog. Well after three days looks like she's got to feeling better. I feel betrayed by the manufacturing. There's nothing to say but Don't Use This Product!!! Your babies will be better off with Frontline. We will never use anything that has their name on it. It's not worth it to us. We love our babies...

I gave my dog a flea treatment on Friday Sept. 25th. After about 20 min he was very restless, agitated and digging at his skin. I gave him two Benadryl thinking it would curb the irritation. It didn't. I gave him a bath using Dawn dish soap hoping to wash the POISON off of my dog. Dawn didn't touch it. Two hours later, another Dawn bath. He was still very restless and irritated at 3 am. I looked at his skin and it was very red, blotchy, and looked burned. I called the vet Saturday morning. Thank God she was able to get his in. She gave him a very high dose of steroid and Benadryl.

I'm so sad and nervous!! I'm mom to two adult cats (Uno, 12 and Gary, 5) and one kitten too young to treat. My Gary goes outside because he insist but the other two are indoor kitties. Of course Gary brought fleas inside and I noticed scratching about a week ago. I went to PetSmart because I couldn’t afford Frontline or Advantage, I read the ingredients of Sentry and it seemed ok. Treated the adults only and left to run an errand, came back both adult males were foaming at the mouth and lethargic. This stuff must be extremely strong, the whole first floor smells like it and after reading reviews I'm starting to panic. I am suing if anything happens. This is wrong and has never happened with any products I've ever used!!

I bought this product from PetSmart yesterday after my 11 month year old Bichon Frise puppy showed signs of fleas. I decided to take the cheap route and purchase this over Frontline. I REGRET IT. An hour after application she started running frantically, digging at the furniture and burying herself, yelping, biting at her skin and making odd noises. Her skin was bright red and that's when I knew it was that poison! I've been up all night and morning rubbing her infected area to try and give her some relief and let her sleep. The minute I stopped rubbing her she would go in a frenzy again. I called poison control and they told me to keep washing her with Dawn and give her half a Benadryl. So far she is recovering but I had my doubts. I don't want any loving pet owners to have to go through the misery I felt. Please avoid this product at all costs and do not take the cheap route!

Sentry flea products are really bad. I have never experienced the reaction my cats are having from any flea medicine ever. I have multiple cats. I have every last one of them drops a couple days ago. My nephew woke me up concerned he had thought the one cat had rabies cause he was like drooling really bad. After drooling really bad he was shaking a lot twitching and having severe tremors. So later in the day I noticed all the cats having problems. If I would have known this was going to happen I would have never bought it and would have purchased Frontline. Also it seems to not kill the flea - I keep seeing them. I also am concerned because my cats keep itching, scared they may have a bad skin reaction and the fleas are still there. Poor guys.

I have a one-year-old Cocker Spaniel. I usually use Advantix II, but I saw this product at Pet Supplies Plus and since it boasted a more natural treatment, I tried it. HUGE mistake. Lexi is a young dog, so she's generally active and energetic. But an hour after applying this poison, Lexi literally COULD NOT be still for more than five seconds at a time. She began panting excessively, hiding under furniture, scratching not only herself, but almost obsessively digging and scratching at the carpet. She would try to eat, but she would get a bite in and jump like something shocked her.

I bought this for my chihuahua and an hour after applying the liquid from her neck down her back to her tail, her skin became tomato red and she started going crazy running in circles, biting at her skin, barking, growling, crying in desperation. It's been 24 hrs and she has not slept (nor have I), not had a moment of peace! She is in bad shape! I returned the stuff to Petco, got my money back but told me they aren't responsible. They gave me half off of an Aloe Vera spray which is not doing much. I want to sue this company!

After recently moving (not by choice) to a new area with my 9 year old male cat, Jax, he suddenly became infested with ticks and fleas. This was our first experience with these horrific little pests, causing both of us to become completely frantic. Jax is a very laid-back feline and has enjoyed good health from day one. The move had thrown his flea treatments off schedule. Knowing our plight, a friend offered this new flea and tick product to me for free. I viewed this as a blessing because the move had taken all of my funds and then some. I accepted and thanked my friend for trying to help. My mistake was not checking out this product before using it...big mistake...huge!! I applied the Sentry Natural Defense squeeze on flea & tick treatment to poor Jax at bedtime. He immediately began to salivate and continued doing this for at least thirty minutes before it finally abated, unlike the very worried feeling that remained with me.

Please do not use this product!!! I have two dogs (age 3). They are brother and sister. My male dog went into seizures for 3.5 hours and was fine afterwards. HOWEVER the female dog is fighting for her life!! She always licked her brother's ears and she got the worse of the toxins. A 36-hr seizure. This began on 08.27.15 at 9 am (fever of 106). Was at the vet by 10:15 am. I was able to bring her home on 08.29.15. She is on Phenobarbital and heavy muscle relaxers. Her motor skills are horrible and can barely walk. We are not out of the woods yet and I am having to give her round the clock constant care. We don't know if she will fully recover... Biscuit and Gravy (my dogs).

After the first application I did not see any adverse effects (other than the horrible smell). However, the second application caused My 3 year old English Bulldog to break out in the worst inflamed skin rash I have ever seen! He never, ever yelps in pain until this product! It is breaking my heart just to try and wash the product off because I know it hurts him so much!! I'm in for class action lawsuit!!

Our cat who is strictly indoor snuck out a couple of weeks ago and we recently noticed fleas on him. Not an excessive amount, but enough to make me aware. We bought this flea and tick control last night at our local animal supply store thinking this was going to be a breeze. We gave him the application between his shoulder blades. The next morning we noticed he was really freaking out running all over the house looking for somewhere to hide. Our cat is typically very social. He was panting and not eating or drinking or going to the bathroom. We tried to coax him out of hiding with treats and wet food (his favorite) but nothing would work.

Used on my 11lb Chihuahua mixed. Her belly was very hot. Washed the stuff off with Dawn dish detergent. I used cool water to help cool her down. They people should be sued. They have no right to mess with our animals like this.

This product is total **!!! I just want to write to the maker of this product and I want my money back. Period. Obviously they know the product is BS. What is making me SO extremely mad right now is that I have a 15 year old Chihuahua who is blind and the fleas are driving him crazy and I was so happy when my husband brought this product home... to only find him running back and forth from room to room in misery! I want my money back so I can buy a product that does work!! FRONTLINE!! I HAVE THE UPS OFF THE BOX.

I put the Sentry Pro on both of my huskies yesterday morning (8/10) and last night my female wouldn't stay still, kept running all over the house, then would lay down. Her nose and head seemed overly warm, and she kept biting at a certain area. I finally pinpointed it and it's the area where I put the flea and tick medicine on. The skin looks pinkish, and when you touch the area she kinda yelps. She is eating and drinking. And from what I am reading in the other complaints, I need to bathe her as soon as I can. The male husky was rolling over on his back a lot outside so I am guessing he's having issues as well. Ridiculous to sell a product like this for animals. They cannot speak for themselves and tell us what is wrong. Stop trying to make a buck and just make a good product.

I bought Sentry about two months ago and put it on my dog. I didn't notice anything at first because I had to leave for a few hours. When I got home he seemed fine. When I pet on him and hugged him I broke out in hives and my hands swelled up. It went away but lasted for a few weeks. During that time I noticed my dog Bayr losing his fur on his ears, anus, belly and legs. He had sores on his neck too. I immediately bathed him in dish soap and have several times since. The fur is just not growing back. I never had any problems like this before! He is always itching and has sores because he is so itchy. I will never use this product again.

Sentry Natural Defense flea and Tick drops - Purchased this product yesterday and applied this morning to my two Maltese. I was thinking because it was "Natural", it would be safer than the other flea control drops. They both hid and sulked all day and their skin was irritated. The drops did not stay between the shoulder blades like Advantix or the other flea prevention products do, but RAN down to where the dog could be able to lick it off if they tried. The dogs stayed in my room sulking.

DO NOT USE! This is a terrible product. Used it on my 10 month old Samoyed. After 15 min she was running around scratching and very anxious. We immediately washed her 2 times with water and soap. She seems to be getting better now, but I am still mad at PetSmart for selling this product and for Sentry for even making such a horrible product.

I have a 15-month old poodle (Ms. Bella Mae). She is very active, healthy, update on shots, and very loved! I had heard of the Sentry Capguard (Nitenpyram) products - tablet form. I thought I would try it because Bella did not like the liquid you put on the neck area. Friday night (7-31-15) about 7:45 pm, I gave her a pill. We played outside, had a very fun evening. Going to bed about midnight, I could tell she was getting tired. Ms. Bella sleeps at the foot of our bed on a blanket.

Shortly after I put this product on my golden retriever -- five days ago -- she started quickly pacing around my home, panicked and agitated, which she has never done before. Since then, she has been almost constantly scratching and biting herself. I plan to take her to a veterinarian ASAP to get some relief for her.

I can agree with the other reviews. My 70-lb pitbull who has skin irritations already is having major muscle spasms in her back and feet. Where the medicine was applied is so painful. She will not even let you touch her. With the other recommendations and reviews I will bathe her in Dawn and have already given her Benadryl. We are going to see if that helps, but if not the vet for sure. This product should never be allowed to be sold!!

I put this on all three of my dogs. One of them was lifeless all evening. Now they are itchy and scratching and digging all over their bodies. I will never use this product again. Found ticks on them too!

Yesterday afternoon (8/2) I bought this product at PetSmart for my cat and today (8/3) he is in bad shape. Not eating, shaking, isolating, and can hardly walk. I just took him a bath to try to take this poison out of his body! I really hope that works! For over 13 years we have used Frontline and Advantage and he has never had this type of reaction. I beyond upset and my kids are crying, thinking the worst. I hope he gets better because we can't imagine something happening to our cat. DO NOT BUY THIS!!!

I put this product on my 6-year old pug around 9 pm. Around 9:30 she started going crazy, running around the house, rubbing herself against everything, then she started panting really loud, then she was convulsing. I then read the warning and said to give the dog a bath using Dawn detergent. So I gave her a bath which seemed to help for a half hour until she started running all over, whimpering, and making a weird bark noise. At this point I have been up all night and had to work real early, so I called the emergency hotline where the guy told me to keep giving her baths and also apply cold compresses and if that didn't work, to put topical vitamin E oil on her. Finally after almost 24 hours later, she is feeling better. And on top of that, I also put this on both cats and it literally gave them bald spots where it was applied.

My own fault for trusting PetSmart, thinking that they actually provide safe products. Sentry flea/tick brand is hands-down the worst. Both of my cats became sick and required a vet visit after using this product. I myself became very nauseous when dealing with the product. It's clear from personal experience and other reviews that this is not a company to carry in any pet store.

It's 12:16 am, my 9 y/o Jackabee is FINALLY asleep in my bed, but wheezing. Applied one tube of this poison this morning (always outside with gloves on). After two hours, the dog was panting, running, anxious, biting his rear like it was really hurting. Couldn't settle him at all. Bathed him in Dawn around 5pm, still no change. I feel assaulted by a company I trusted and I can't wait to tell both PetSmart and my Banfield Vet what I think of this toxic waste. Even our cat, who never goes near the dog, threw up bile. We have had a horrible past year, due to the heat & humidity, but I will never use this product again.

I took our shop dog to PetSmart on Tuesday to be groomed. While I was there I purchased Sentry PRO XFT40 flea & tick squeeze-on for dogs. It was on sale for $12 for a 6 month supply (should have warned me). Upon returning I immediately placed the tube on her neck/back area and with a few hours she was anxious, pacing, itching (after just receiving a flea bath), frequent urination, loose stool, etc. The following day she was still experiencing these problems. I finally looked up side effects from this Sentry product and found many more complaints that matched my description. I have now bathed her AGAIN in Dawn dish soap and am hoping for better results this afternoon.

Gave my dog Sentry flea med yesterday. Noticed it seemed to puddle on her back unlike the name brand. Early this morning she was too warm, wouldn't eat, listless, no drinking water. So I Googled the related deaths from this product and immediately bathed her. Instant change! Right away she Ate big bowl of food and is running around. Dodged a bullet!!! Hope this helps someone if they have this problem. Bathe dog and toss this crap! She's a snorkie. FYI, told they have sensitive skin.

Fiproguard Plus for dogs (fipronil, 9.8% and (S)-methoprene 8.8% - This product was applied to a 90# and a 100# Golden/Lab mix in July, 2015. Fleas were continuously present for 4 weeks on both dogs, and each dog spent an unusual amount of time flopped over on their backs, rubbing it on the ground, as if it were a constant source of irritation. At $47/3 doses, it seems like a class action is in order.

I purchased Sentry Pro flea and tick medication last week. It is poison. I was going to the mountains with my two dogs for four days so I bought this product and applied it as directed. Within 12 hours, one of my dogs was panting, jumpy, restless and scratching like crazy. Knowing that nothing else in their last 12 hrs was different. I Googled the product and was shocked at what I found. It can lead to paralysis, seizures and even organ failure. My Diego's reaction was also common among the comments made here. I am appalled not only that Sentry makes this poison but that Petsmart sells it. I had to cut my vacation short and get down the mountain so that I had access to an emergency vet if necessary.

We gave our 3-year old male pug Sentry Pro XFT in the morning, left for work and arrived home to a very sick pug. It's now 24 hours later, no sleep for him or us, $120 emergency vet bill, four baths with Dawn soap, Benadryl, and steroid shot later and STILL he is pacing, erratic breathing, scratching, restlessness, moaning, and fever. As a pet parent I feel absolutely horrible that our pug was exposed to this at our own doing. This product should be taken off shelves (PetSmart)!!!

I purchased this product(Sentry fiproguard plus) for my cat and dog not knowing about it but on the box claims to be the same as Frontline. I applied the first dose waiting about 15 days. I knew it was not working so I applied another dose thinking it would work after that but it is doing nothing. I spend 181.00 for this product. I think I should be entitled to a refund for the remaining product.

I have a 20 lb Boston Terrier that we just found out has flea allergies. After applying it to him 6 days later he STILL HAS FLEAS!! This stuff "claims" to have the same ingredients as Frontline does. If it did... it would work!!! I will NEVER recommend this ** to anyone.

Yesterday around 9 AM I applied "Sentry Pro XFT" to my 3 year old Puggle and left for work (first application ever). I got home in the afternoon and was told that she'd been scratching and shaking some during the day. By the late evening (about 9 PM) she was inconsolable. My wife tried to pet her and mildly scratch her back, and she yelped very loudly, obviously in pain. I read the back of the package, which suggested bath and "rinse with large amounts of water" for the continued sensitivity. We did that, and it seemed to help, for about 10 minutes. 30 minutes after her bath, she came over to me, wrapped her tail closely around her and sat down, her bottom pulled in tight to her legs. She looked up at me with her ears down and back, I could only imagine her thoughts as she sat beside me looking at me (this is highly unusual for her, in fact I don't think I've ever seen her do this).

We used this product on a 3 year old Alaskan Malamute and a 7 month old Leonberger. Two days later we were sitting at the Emergency Animal hospital at 2:30 AM! This was almost two months ago. After all the complaints this product is still readily available. Why? The Leo was biting and scratching at his rear end. The malamute was trying to tear out his own throat. We went through a miserable week with them and Sentry said it was because we applied it improperly. I can't count the number of times we used Advantage and/or Frontline on the dogs in the past 35 years. Never once wound up at a vet!

It is 3:45am. I gave my 2 small dogs this flea product around 8:00pm. Within an hour, one of my dogs started whimpering and having tremors. I thought it was just him because he does have a weak stomach. He cried and cried for an hour or so until my other dog started crying and jumping around. They are restless. I tried to walk them outside, my boy didn't even raise his leg to pee. He squatted!! I have given both of them baths in Dawn. It is no help at all. I am sitting in the bathroom with them trying to keep them as quiet and comfortable as I possibly can. This is absolutely ridiculous!!!!!

Do NOT use this product!! Tried this because it was a little cheaper. Needless to say just an hour after applying, I could tell something was not right with my dog. He's a 45 lb wheaten terrier. He has been crying, shaking and in distress. It's now 2 am and I have given him 3 baths now to wash off this poison!! After reading the other reviews, I won't be sleeping tonight. Not worth it - this product needs to be off the market immediately!!!

I have 5 cats, and I purchased this product to save a little money. It claims to have the same active ingredient as Frontline. We followed the directions on the box when applying it to our cats. My 13 year old cat started to salivate heavily within minutes of the application and lost her appetite. The other 4 cats were lethargic and lost their appetites as well, but were fine after a couple of days. My 13 year old cat died within a week of using Sentry on her. My husband and I thought it was because she was old, and it was her time.

My cat and dog still ended up with fleas and my dog has white hair and this turned his hair yellow like pee. My house became infested with fleas and NEVER will I use this product. So disappointed. I will stick with Frontline - it's truly the BEST for the money.

I gave my dog the Sentry Pro flea and tick squeeze-on for dogs last night. Within and hour he was acting very hyper, trying to gnaw at his paws, legs, tail. He wouldn't walk long to go to the bathroom and would quickly sit down and act paranoid. I can't believe the other reviews that I am reading were the same side effects that my dog is having. I'm just washed him and gave him some Benadryl. I am hoping he returns to normal soon. I want this product off the shelves now. I'm calling the news here in Los Angeles right now.

I bought this product as a supplement to her monthly flea/tick product. Flea season is bad where I live this year. When I first put this product on, I did not notice anything strange. But within about 3 hrs, my dog, a Pug, was going crazy. She was crying, rubbing her body on the ground, and just hysterical. I started researching this product on the internet and can not believe this is still on the market! I am now doing the washing with Dawn soap (2x so far) and just trying to console her as much as possible. This product should be pulled off the shelf! DO NOT USE!

Please, please do NOT use this product! It gave my beautiful eight month old golden retriever puppy a horrible chemical burn after a typical application where I followed all instructions. Even after three washes and emergency vet treatment, she is in extreme discomfort. I repeat - do not use this awful product! Given its track record, which I have since become aware of, I am shocked and saddened that it is on the market.

Sentry Natural Defense flea and tick for cats - This product made my cat lose his fur where the product was applied and the skin has become infected, with blood and pus. He has lost his appetite and is lethargic. I took the remaining 2 tubes in the box back to Petco and they refunded my money. But getting the money back is no trade for the suffering my cat is going through right now. I feel sick about this, an awful product!

This is the worst product ever. I use it on my cat. Still has fleas. You we shampoo still has fleas, used carpet flea powder still has fleas. Treated the cat again and still has fleas. I am allergic to fleas. This is the worst product paid $10 for. Some of this stuff is the worst product. Take it off the market. Somebody needs to do a class action lawsuit.

After giving my baby this product as directed, his eyes dilated and never shrank. Two days later I had to put him to sleep. He could no longer walk. The blood was nearly drained from his weak body. It was awful. I don't usually use over the counter flea meds but thought I would give it a try because he was infested. I am heartbroken. Then I was told that this brand is one of the worst for toxicity to animals. I'm angry.

I applied Sentry Flea med on the backs of my two Beagles. Within minutes of application they both were restless, trying to scratch and rub off. One of my Beagles started shedding terribly, the other lost a patch of fur and his skin became very pink. Thankfully they both are ok but I will not apply the remaining tubes in the future. It was not worth the pain my pets endured to save a few bucks. This stuff is no good!

We purchased the Sentry Flea and Tick Squeeze Treatment from PetSmart and applied early morning. By evening our dog was lethargic, breathing heavily but shallow and wheezing, shaking and completely not his normal self. He then proceeded to vomit twice. We noticed he was extremely hot to the touch. The next day he was still somewhat lethargic and would not drink water. Today we noticed his lips were swollen and he was still warm to the touch. He has had loose stools as well and has been scratching. I would not recommend this product to anyone. Alternative options may be more expensive but it is not worth seeing our beloved family pet as he has been for the past several days. After reading the other reviews, we have immediately washed him in Dawn dish detergent and are hoping to see him return to normal.

Some cats react differently to medications. My cats haven't had any bad reactions to PurrScriptions Plus but that doesn't mean your cat won't have a reaction. Other folks have had good experiences with Frontline. One of my cats nearly died from a reaction to Frontline. Apparently she is allergic to methoprene. If you think you can just put some medication on your pet and fleas will go away - well maybe it happens if you're lucky. I used PurrScriptions Plus, bombed the house twice, put cedar chips in strategic places (places I can't easily clean), brushed Borax into my carpets (neat trick - it cuts them up and they dry out and die), and then we finally had no fleas. I'm not saying it's good. I'm not saying it's bad. I'm saying that with any pet medication you must watch your pet closely because there can be a reaction - just like you can have an unexpected reaction to medication.

My 23 lb French Bulldog had a severe allergic reaction to this product. This was the first time we used a Sentry product. There was no warning on the packaging about any adverse reactions to the product or suggestion to do some kind of sensitivity test. The dog became hyperactive and panting and twitching within 2 hours of application. We gave him 3 baths using Dawn dishwashing liquid and gave him children's Benadryl. It is 36 hours later and he is still having problems that are very slowly getting better. No one slept last night!

As with most of the complaints on here, I gave my two dogs this application and within an hour I knew something was wrong. It is now 5 hours later at 3 am and I am bathing my dogs trying to relax them. I have used numerous kinds of these products in the past and never had anything like this happen. I am so upset that I caused my sweet boys so much discomfort. This product should be removed from the shelves!

Not long after I used the natural flea medication on my cat, he began drinking a lot, lost appetite, lost over 3 pounds, and developed ulcers on his gums. Diagnosed with kidney failure. Only a 2 1/2 year old cat. I am convinced this product was toxic to my cat and led to kidney failure. I've seen other similar reviews. How does this become a class action lawsuit?

I have an 11 year old pom and just brought home an 9 week old mini Aussie/heeler puppy and bought this product without first reading reviews. I bathed both dogs and later applied the product to them. Nothing out of the ordinary happened until after I read these reviews and decided to get up and bathe both of my babies in dish soap. Now it seems they are both scratching and my puppy is steady licking her foot and seems like she cannot relax. I don't know if it is me being hyper sensitive but now I'm extremely worried. If things are not better in the morning, we will be making a trip to the vet. I am praying for no ill side effects. But my question remains... WHY IS THIS PRODUCT STILL ON THE SHELVES?!?! I would be heartbroken if something happened to either one, or both, of these precious babies!

Almost instantly after applying the product as per directions, my dog was clearly uncomfortable, in pain, and even acting paranoid and scared. I washed him off with cool water. This did not seem to be enough, so I then shampoo him and two days later he has welts where I applied the product, his belly has a rash and his ears are covered with red bumps! He has been running a fever of 103.9 since I applied this poison! I am furious and I would love to apply it to each and every ** who is responsible for this toxic product. Shame on you!

Exact same story as all of the other ones. Woke up at 3 this morning to my dog whining and running around. Read these reviews, and not to be dramatic, but probably saved my dog's entire back. I put Dawn soap on his back, washed the product off and then put Benadryl. Thank god he's fine now, I got luckier than some of the others, but I want this product off the market. I called the Sentry customer line and they moved me over to their emergency medical line. The customer service alone was awful, but the things she was saying were worse. She told me it was a dry skin battle and vitamin E would be fine. I told her that he has dry skin, we put vitamin E on him all the time and that wasn't this. I told her I had the same experience as all of the other pissed off people on this site and Amazon.

Gave my dog the sentry flea and tick as directed on her back. She became agitated, restless. She could not get comfortable. She was itching terribly, and after 4 hrs I checked online saw negative reviews, bathed her in dawn and off to the emergency animal clinic we go at 3am. Home at 4 am and back to the vet this morning as she is still not doing well.

Below is a copy of the review I had written on Sentry's website for this product. Received an email back the next day that they won't post this as it didn't meet their website guidelines. Go figure - if you rate something bad they just won't post it!!! It's been 2 days now and my dog is still having issues.

This is the first review I have ever wrote, but I wanted people to know this happened to my pet too. I bought Sentry PurrScriptions Plus from PetSmart. About 20 minutes after I applied it, our cat was violently throwing up. Then I noticed fur missing where I applied it, and red burn on her skin. I felt terrible! I just wanted to prevent fleas and ticks. I read the instructions again to make sure I applied it correctly, and I did. I also checked to make sure I bought the correct weight for my pet, and it was correct. Hopefully with enough bad reviews, they will not sell this product anymore.

I purchased Sentry PurrScriptions Plus for Cats over 5 lbs for my 5-year-old cat, Peanut. After reading the other reviews on this site, I'm grateful that she only had a mild skin reaction that made her very irritable. She was whining at me trying to tell me she didn't feel good. As other reviewers suggested, I washed her 3 times with Dawn dish liquid. She was such a good girl! I panicked and took her to the emergency vet where they gave her a shot of Cortisone and said if she wasn't vomiting she was probably okay. I'm all for an inexpensive way to prevent fleas and ticks and mosquito bites, but not if it's going to make my animal miserable.

I put this product on my dog about 6pm today and now it's after 1am and she is up restless scratching and rolling around and vigorously licking and making sounds with her mouth because she is salivating soo much. She can't sleep and neither can we. After reading all these reviews I think I will probably have to take her and put her in the bathtub right now in the middle of the night. I gave her Benadryl already but she is still acting funny. She has never had fleas - just found a tick on her and I have never used any treatment. She is better off without this stuff I do believe! Taking the product back to the store and throwing it in Petsmart's face.

I put the product on my dog to protect against fleas and ticks. Within hours she became anxious and agitated, her tail went crooked. She won't relax. I called the number on the box, they said wash with Dawn dish detergent. And it will clear up within 48 hrs. My poor dog is very uncomfortable.

I feel like I have given my dog poison. I have a 25 lb Cavachon and purchased the Sentry product at PetCo hoping they know about the products they sell. By the next morning "Khloe" was obviously in pain. Almost like when I had shingles, she scratched and twitched indicating to me that this was something neurological. She has been awake and miserable for two days. I finally looked online and read the numerous warnings from other pet owners. Shame on you Sentry and for PetCo continuing to offer it.

I should have listened to other consumers on this site but I took my chances anyways because my dogs really needed tick medicine. BUT NEVER again will I buy stuff from this company. I trusted them, but it looks like I should've trusted the reviews. My dog is not acting himself now and he's frantically panting. His hair is balding in one spot on his back and he won't leave it alone. I can barely touch the area without him crying. He's acting out and only feels better if we constantly pet him to get his mind off the area.

Within a couple hours of giving both my beloved Westies they were panting, running from room to room. Rolling in the grass. Rubbing under cars to get the product off. Acting like crazed paranoid dogs. I wash them and called company. They felt above us. I will take them to the vet in the morning. We have health plans for both dogs and are very disappointed and frustrated. Sentry advised not to take my boys in. DO NOT BUY.

I purchased Sentry Pro for my 6 year old Aussie. Just hours after application he started losing fur, by the next day he had bald spots on his shoulder blades and by his tail. He then started to become more lethargic and refused to eat. I took him to the vet and they confirmed he had chemical burns secondary to the medication. He was placed on medication, bathed with Dawn, but is still very much not himself. He is back to the vet today because of continued lack of appetite and energy. Please DON'T BUY THIS!!!

I applied Sentry Fiproguard Plus to my dog, and she started itching soon afterwards. My husband thought she must of had fleas and the product is making them move around. Over the next week her itching got more intense to the point I knew something was wrong. I took her to the vet where she got 2 shots. Her skin was red, her ears looked horrible, and she had severe itching all over.

It was time for my two cats and one dog to receive their monthly flea treatment and I decided to try this product because I had seen it on commercials and it is a little cheaper. After 6 hours, my younger male cat started having seizures and vomiting. I saw no evidence that he licked it and it was applied high on the neck and should be impossible to reach. I washed the product out with dish soap since I had read that many people on this thread had to do that. After another hour of him continuously shaking and crying in pain I parted the hair on his neck and saw huge burns. I applied Benadryl cream and calamine lotion to try to help. He will be going to the vet in the morning.

I used your product Sentry Fiproguard for dogs on my 70 lb. Shepherd/mix. The odor is so offensive that I can't wait to bathe her. I have never used a product so offensive in my life. The package came with 3 doses. The remaining 2 doses are in the trash. Hopefully your product works. I'll never put your product on my dog ever again. In addition, your product turned my dog's black hair, white. I am unable to pet my dog as the odor transmits to my hands. Why does your product stick the high heavens?

Our dog has had a bad reaction. Do not use this product!!! Never with other oils, only this brand. Other reviewers said same thing -- poison.

I read the box and it said nothing about an older cat taking this. I gave these to my sweet Patches May 1 because her fleas were so bad. She was 20. I could tell she got relief from the drops. About a week later I noticed she started going down. I thought it was her age, that it was her time. But the cat was as healthy as a 3 year old. She died today, May 18. I think it was the Sentry because she was in such good shape before the drops. So, be sure to ask your vet before giving your cat Sentry flea drops. And she did not die a pleasant death.

If you are reading this at 4 am after applying Sentry to your dog and they are in pain and freaking out (as I was 2 days ago)...go wash them in DAWN dish soap ASAP! I cannot believe this product is allowed on the shelf. We bought the product at Petco and applied as directed. Within an hour our dog became restless and agitated. As the night went on symptoms got worse. Thank God for this site and the recommendations. It has been 36 hours and she is still not herself. In addition I have a cat that is now throwing up (even more worrisome) since last night. HORRIBLE PRODUCT & SHAME ON THE MANUFACTURERS.

Used it on my dogs and didn't kill nothing. Fleas were worse and made red wells on my dogs and very deathly sick. Tried to write to company, asked for a refund, no response.

I purchased Sentry Natural Defense Flea & Tick for Cats at my favorite local pet store. They focus on natural, eco-friendly products and I've trusted them for years of happy purchases for my cat. I decided it was time to start treating my 5 year old cat for flea and tick prevention because it's getting warmer again and opted for Sentry Natural Defense because it was the only one offered at the store and I thought going with a natural option would be even better than the products I had used on her before. The moment I applied it between her shoulders she ran away and a profusely started frothing and foaming at the mouth. Her eyes were watering and she was running like she was being chased or in pain. (When applying other flea products in the past, she hasn't even noticed or reacted at all.)

I bought Sentry Natural Defense Flea and Tick shampoo and ointment for my dogs because it says it is Natural, Safe and not toxic to mammals, fish and birds! It killed our Corgi. There are so many complaints about these products and are still sold in the stores to people who want an alternative to chemical applications and buy them only to find out they are toxic to some animals. It is the saddest experience to know a healthy dog was poisoned with a product that was labeled safe. I am writing this so no one else has to suffer.

I have used this product in past years with no issues, but today, after applying Sentry Natural Defence Flea & Tick treatment to my 3 year old, 100# Rottweiler, she immediately began to act strangely. Squeezing herself into small spaces, unable to get comfortable, panting, and rubbing around on her back. I thought I better check online for something and found this site (wish I would've previous to applying). I gave both Rotties a bath, with Dawn, and hosed them down thoroughly. My 10 year old Rott didn't act strangely, but I wasn't taking chances of something happening later, or it getting on the cats and affecting them. I will be returning the remaining 2 doses and letting them know about this site and my issue. Hopefully they will remove from the shelf.

I bought this product at our local Petco while I was picking up dog food. Applied to my pugs around 4 pm Sunday... It's now 9 am Monday and my pugs are at the vet after a very long uncomfortable night. Their behavior was very bizarre, very restless, hiding in closets and under beds. Muscle weakness began around 7 am followed by foaming at the mouth. I bought this product because I want to take care of my pugs so they have a long healthy life, the manufacturer however seems to have other ideas of what that entails. My vet's recommendations were to stay clear of ANY of their products. PLEASE be very careful and always check with your vet before using any new product on your animals. The price point on these products is appealing, but in the long run cost me vet visits for two dogs and a day from work and a ton of stress seeing my babies so sick.

Made My poor 6 mo old cat so sick. I am amazed she even lived through it. Thank goodness no remaining problems after two months. Her personality is back. I am so mad this stuff is even on the shelf. It was much less expensive than the leading brands and I was on a tight budget too. I wondered why it was so much less expensive, NOW I KNOW. Reading the reviews from this site it should be banned!!!

I honestly believed this was the same product we used in previous years. However, this time our dog had a very bad reaction -- scratching uncontrollably, rubbing against anything, and crying in pain. Called the vet who confirmed others have had this problem and told us to bathe in Dawn dishwashing detergent. It helps but she is still scratching a lot. Hope more people google this product before purchase.

I put Fiproguard Max flea & tick on 8 cats in PM. By AM 4 cats had huge patches of fur missing & their skin was red open sores. The areas of their necks that were affected ranged from cat to cat & measured from 3x2 to 5x3. I bathed all my cats after, & won't use this product again.

I had used Sentry Fiproguard for a few months and did not have a lot of trouble but then one of my cats got blistered by the solution and I found the Sentry Natural Defense that they claimed was effective but gentler on the system of the animals. The first time I used it on my cats (2) they smelled wonderful but soon began being very lethargic and seeming like they were drugged. They lost interest in eating and drinking and were not active at all. This was very unlike them as they were both always running and playing and spatting with each other and they acted like they were starting to die.

We adopted our Vizsla Finnigan 5 years ago. He was about four when we got him. He's lived in the house with the family and we have not had any issues. The day after I applied this product the dog bit my 25 year old son on the ear when he leaned over Fin. Fin bit down and wouldn't let go. 14 stitches later and a wonderful visit to the urgent care, I am afraid I will have to put my dog down. I can't say it is a direct link to this product, but I sadly won't have my buddy around, and I'll always wonder if it was this product that made my dog aggressive. :-(

I just purchased this item today along with the shampoo and spray for the house. So far my puppy hasn't reacted bad to these products but now I'm really scared for buying this. If I would've known I wouldn't have bought this for my 3 month old shih tzu/cocker spaniel mix. Please if y'all recommend something out there more affordable and with fast results for fleas please let me know. I'm in desperate need of having this taken off her body!!!

Sentry Pro XFT - I put this product on my Pug Sunday afternoon and within an hour she began acting strangely. She was pacing and panting uncontrollably. I called the 800 number on the box and was told to give her the 3 baths with Dawn dish liquid. The baths gave no relief. I called my vet first thing in the morning. They gave her a steroid shot and a shot to help her sleep. She still paced and panted. They had me give her zanax to help relax her. That worked some but not a lot. Now this morning she keeps twitching her head to the left and has a bad cough with terrible breathing. Going back to the vet. POISON!!!

I bought the Sentry Pro XFT yesterday to protect my dog (sheltie mix) against fleas and ticks. Within the hour my dog was running around from room to room, rolling on the floor trying to rub his back, shaking like he was trying to get water off of him. After a couple of hours of this I went online and read other reviews of other dog's having similar reactions. We rushed my dog into the tub for a Dawn dish soap bath. All evening and most of the night, he was agitated, restless, no appetite. It wasn't until almost dawn that he was finally able to sleep. I feel that a product that gives such severe reactions should not be put out on the market. I will never use a product like this again.

I tried it on my Italian Miniature Greyhound, I couldn't get the Advantix 'cause of the pet store burning but I will be getting it this week. I had been using on her which is very good so I tried this and it is sorry I killed the fleas the first. After that they got even worst so I been giving her flea baths. So decided I try another tube and they got even worst. And I will never buy it again. I think I deserves a refund of 32 dollars. I got mine from tractor supply but I will tell anybody, don't waste your money on it. If you love your pet as I do, you will spend the money on flea medicine that actually works, not one that feeds the fleas to multiply them three times as worst. This product really sucks... If I could add the receipt, I would.

Sentry Pro XFT 61 Flea and Tick for Dogs - Don't EVER put your pet through this!!! 45 minutes after applying this product to my dog, he began whimpering and yelping, as well as, frantically rolling around on the floor. I bathed him 4x with Dawn Dishsoap, as advised by the Sentry medical department and my veterinarian. 26 hours later and he is still whimpering, won't go to the bathroom, won't walk, and won't let me touch him. It is brutally heartbreaking to watch, and apparently, there is nothing more that can be done.

We applied suggested amount of oil on her back as indicated on box. She started to act sick and irritated within hours. She continued to feel worse so I looked online for suggestions and found many pet owners with similar complaint. I washed her 3 times but I think it was too late to stop the side effects. She is falling over when she tries to walk and has lost her normal balance and hind leg strength. It has been almost two weeks now and I am very concerned she will not recover. We had her vet see her yesterday and she thinks the neurological symptoms are from the drug we used in this product.

Using the right dosage and reading all of the instructions still resulted in an allergic reaction in our dog. When I called about the symptoms, the company had someone on staff explain procedures to remove or at least reduce the dog's suffering. She explained his hyperactivity and inability to lay down was because his body felt like he had "pins and needles" throughout. After a rinse and repeat three times and rubbing vitamin E oil on his fur, he calmed down in about 6 hours. The treatment was administered at noon, his reaction was at 3. She said the problems could persist for 24-48 hours. My anger is obviously about my poor dog's pain, but also, since the company has experienced this issue many times before, why isn't this information and warning on the package?

I purchased this as I prefer to use natural products around my house. It had a spice scent. Not sure why a scent is required at all. I applied to all three dogs at the same time. They are pretty much soaked with the product due to them being short hair. The whole house stinks of the product. It's everywhere. Day 2 I had to bathe the dogs, wash all their bedding and my bedding and all my floors as there is oil everywhere. This product is disgusting. Not sure how it ever made it out of their R&D department. Have asked for a refund. Do not buy this. Your house will be covered in it.

This is a horrible product! After pulling 2 ticks off of our dog we bought Sentry pro xft for tick and flea protection. Almost immediately our dog was frantic pacing around the house all night. He could not sleep. He was begging to go outside almost every 15 mins all night long. He was in panic mode. I don't think he knows what to do with himself. He has been crying and itching and panicking for almost 24 hours so far. After we have now spent $200 in vet bills today they finally have our dog sedated and said this could last 2-3 day. Our dog is miserable. I will never use this again and I will tell everyone I know to never use this product.

Trying to save money and without looking up the reviews on this product, I purchased Sentry Pro xft at Petco. What a huge mistake I made. After applying this on my shepherd, she whined, paced back and forth to try and find a comfortable spot, she twitched, scratched where was applied. She could only get somewhat comfortable if she was up in our face. I also got some skin burn from her getting up close in my face to get comfortable. I had to wash my face off with dawn dish soap. She was no longer herself, and you know, our baby. My pup did this all night long thru the next day. After I noticed she was not herself an hour after applying and washing her with dawn dish. My shepherd is in pain. My husband And I will never buy a product unless it’s looked at beforehand. I looked up the reviews, this needs to be taken off shelf immediately. Do not buy this product!!!

I went to Petsmart to get some flea preventative for my three boxers. Money was tight so I spent about twenty bucks on Sentry Pro. I thought a good mid range priced preventative would be ok. Several hours later, my female boxer started convulsing. Her legs became shaky and she was panting. I have never seen anything like it. I Googled the symptoms and found this forum. I plan on returning to the store tomorrow and try to return it. I washed all three of my dogs. My daughter was losing her mind very upset. I wish I would have spent my money more wisely. This stuff should be banned. I plan on letting Petsmart know my feelings.

Both my little dogs got their flea drops (for small dogs 6.5 to 22 lbs) at the same time. Both immediately went crazy as if they had been stung and whirled and whined and tried to rub their backs and face on anything near. They panted and acted freaked out. The smell was very strong and filled the air in our little house for days. I let them outside where they rolled around and ate grass. When they came in I tried to see the spots I applied it but could not because they both have very dense undercoats (Pomeranian and a shih tzu mix). My hands were burning and red from parting their fur. My feet were burning from walking on the carpet where they had rubbed. None of these problems have diminished with time; it has been a week... my pom holds her one ear down, tilting her head ever since. The shih tzu mix who weighs twice as much as the pom is getting better. My hands still burn when I pet them and if I go barefoot on the carpet my feet burn.

I noticed my pit bull puppy had patches of no hair, and irritated skin. Later found out it was demodex, so I go to petco and ask for a repellent or cream of some sort to keep them from coming back and/or kill mites. I have used the sentry antibacterial topical treatment on her, and saw no bad reactions however when I used the fly and flea repellent, my dog has not been herself. She can barely walk, and when she tries she falls on her side, losing balance.

I purchased a box of Sentry Natural Defense Flea and Tick Squeeze on for Dogs 15-40 Lbs from Petsmart. I asked the clerk about the product, and was told it was a good product that they sell a lot of, and had less pesticides than other products. I read the directions and applied it to my two year old Maltese Lucky. I went to work, and when I returned that night, he started acting very weird. He was wandering around the room with a scared look on his face. He started shaking violently, and I picked him up to try and calm him down. I sat with him on my lap shaking, trying to figure out what was wrong with him. Then he started panting real hard and kept looking all around the room. As he started to shake more violently, I realized it had to be the Sentry product, the only new thing he was on.

I purchased the Sentry as an alternative to Frontline. I had applied 2 previous applications to my small terrier with no adverse effects but yesterday was a different story. He immediately began rubbing his back against the carpet, desperately trying to remove it. But his behavior was strangely "off" for the rest of the night. He's normally hyperactive --- none of that. Quiet, lethargic and restless. He couldn't seem to get comfortable. But I knew something was really wrong when he lifted his leg and urinated right in the living room without indicating he needed to go out. After reading all of these horror stories, I can't wait to get home and give him a bath. DO NOT USE -- the savings is not worth your pet's health.

The only flea medication our cat got violently ill from. I can't believe this product is legal.

Both of my cats are now missing fur where I applied this medicine. Reading the rest of these reviews scares the hell out of me. I hope they will be ok. This never happened with the other medicines that I used on them. How is this on the market???

Was using Sentry Flea & tick Shampoo for a week & this Saturday applied Sentry Flea & Tick Squeeze-on on 3 dogs. In 24 hrs. 3 dogs had watery eyes, 2 could no use their hind legs and shaking. One of the dogs had the worst symptoms drooling, eyes rolling back, panting, walking stiff and would fall over... took two to the vet, one was left there all day on fluids and testing. Hundreds of dollars later test ruled out other causes leaving the one constant... Sentry Flea & Tick! All 3 dogs were healthy and running and almost died from this company.

We applied Sentry Pro XFT to our 6 year old female Shepherd Shiba Inu Mix Sabrina. After about 4 Hours we noticed a twitch in her left rear leg but didn't make a connection to the flea treatment. But 8 hours after treatment it was clear she was having a reaction to it - she was crying irritable and would not lay still all night long. We called the 800 number on the box. Thank God there was actually a person answering the phone that was very helpful. We were told to bathe her in cool to room temp water and Dawn dish soap (we did this twice with a good rinse), put ice packs on her treated area and put vitamin E oil on affected area. She is still in some distress but it is quieting down. We were also told this could last up to 48 hours. We have used this product in the past with no effects to Sabrina but will not be using ever again.

When I put the product on my cat that I had since it was a baby (for 9 years) it immediately freaked out and then for 4 days it ran around my house like it was crazy or high on something and then one morning I woke up to go to work and found my cat dead in my closet with foam at the mouth and cat poop everywhere. I followed the directions exact. My cat was totally healthy and two weeks prior went to the vet and was given a clean bill of health. Your product killed my family member (my beloved cat Babykitty, a black, long-haired Persian cat). I feel that Sentry needs to compensate my family for the death and anguish and our loss. I am going to seek legal action against this company. That's all I'm going to say for now.

Sentry natural defense flea and tick - I used it on my dog in the afternoon and by the morning my dog couldn't walk. It took him about 4 to 6 minutes to be himself. I have to him a shampoo. I call the company and I demanded my money back. Please be careful what you get. I keep my dogs as natural and poison free.

I applied Sentry Pro XFT to my 20 lb 1 year old dog and within 2 hours he became anxious and running around in circles. I gave him a bath in Dawn and took him to the Vet which gave him a shot of Benadryl. Five hours later he still has discomfort so I gave him another Dawn bath. Cannot stand to see him like this he's our baby. Praying he will be better by morning. I called Pet Supplies Plus where I purchased the medication and told them it needs to be taken off the shelf. I was told they only take products off the shelf if there is a recall by the manufacturer. With all of these bad reviews something has to be done!!!

I wanted to warn everyone not to use this product. I was using it as a preventative, since Let her go outside on a harness sometimes and wanted something natural instead if all those crappy chemicals. Two days after putting up with the nasty, overwhelming stink... turns out my cat had a bad reaction to it, and her hair at the application spot fell out and is bald. I quickly bathed her after noticing and will call my vet tomorrow to ask questions. It smells through the whole house and my cat couldn't stand the smell either. She sneezed lot too. I read many places peppermint can be toxic to cats and it is one of their ingredients.

I decided I would give my 85 pound Bernese Mountain dog a bath on Saturday and then wait till Sunday night to put his Sentry treatment on. Sunday night I put it on and "attempt" to go to sleep an hour later around 9. After listening to his nails pace on the hardwood floors and his collar shaking for an hour, I got out of bed and let him outside. When the extreme panting and the pacing got worse, I gave him three baths and had to sleep on the couch. He could finally fall asleep around 2:30am and that was only because he was sleeping on top of me. This product needs to be pulled from the shelves! I have never seen him act like this before, it was horrible. I called my vet this morning, they hadn't ever heard of this before. I will make sure they are aware when we are there on Saturday to get REAL flea & tick preventative.

We recently got a 2nd puppy, Brutus 9 weeks old, so our other puppy, Mongo 8 months, had a brother and playmate. After getting Brutus, we opted out the more expensive flea meds Mongo had so we could spend money on more food and toys for the boys; big mistake. A few hours after applying, Mongo started itching, and his ears started twitching and he whined constantly. I know flea meds can be irritating when first applied, so I disregarded it as him just being a sissy; Brutus was fine. The difference here is Brutus had the "gentle, small breed", where Mongo had the 40-60 lb version, so it's stronger. After about 10 hours of nonsense, I Googled "sentry pro, dog crying" and the first thing that came up was TOP 348 COMPLAINTS.

I purchased this for my service dog and put it on him on March 5, 2015. Later that day he started to whine, shake his head, and bite at his side and near his tail. It continued to get worse his skin was red, and felt hot to touch, his whole body felt hot. He was panting, and stressing out to the point he wouldn't eat and could not even sit, or lay down for short periods of time.

Very soon after applying Sentry to my cat, he began twitching and his eyes were glossy. Because he was already so upset I decided not to fully bathe him. Using 10 washcloths soaked in Dawn dish soap and water, I scrubbed his neck and then repeated with water-soaked cloths.

Sentry pro flea and tick - I bought the drops for my Yorkie and my lab mix. Yorkie appeared to lose control of his right side and was panting like crazy. Shaking like he was freezing. Seemed wired. Lab is bigger but she also panted like crazy and was nervous acting. Fine now, scary situation. Be careful using this product.

Wash your cat immediately with dish washing liquid!!!!!! I purchased Sentry flea and tick remover yesterday, I applied it at about 5:00 pm. My cat is a new mom so when I noticed a few fleas, I went to PetSmart to make sure I would purchase the correct thing for her and her kittens. She has been very attentive with her kittens. We set her up a box and she has not attempted to move them or anything. Later we noticed one of the kittens had been moved because she was crying in distress as if she didn't know what where it was. We found it under the bed but we noticed momma cat was shaking about 2 hours after application. I thought it was just the process but when I awoke to her moving another kitten at 4:00 am the following morning, I Googled it and found this forum. Wash your cat immediately with dish washing liquid as it will help to remove the oil from her fur.

I used Sentry in October because noticed a flea on my gorgeous shih tzu. Week later I noticed he had bleeding under his skin and whole areas on his body got burgundy red. Now by March he lost almost all of the hair on his back. Thanks a lot!!!! This so called "product" should be removed from shelves immediately. Stop hurting our pets. Oh, and by the way it never killed that flea I found it running happily a month after using Sentry. P.S. Never had any problems with Frontline. Very frustrated...

I purchased both Sentry pro XFT for small breeds 11 to 20lbs and Sentry Pro XFT for dogs 40 to 60lbs. One we got at petco in the sale bin and the other at Cabela's. The first time I used it on our big dog, she had the worst reaction. Poor thing kept jumping up and running across the room and quickly laying down like she kept getting electrical jolts. Then as soon as she lay down she jumped up again and repeatedly went from spot to spot unable to get comfortable. This kept happening and I was trying to figure out if it was because I gave her a haircut and that she felt weird about it. I realized I just applied the sentry medication as well.

Yesterday I bought and used the Sentry Pro XFT flea/tick repellent on 2 of my dogs. It didn't take long for BOTH of my dogs to start going crazy like their backs were on fire and itching. I waited to see if they would calm down. Gave them Benadryl last night which helped them calm down and sleep. Gave them a bath this morning after reading all the complaints. But they are both still acting like they are miserable. I feel bad for not checking reviews first.

I so wish I had checked the reviews for this product before I purchased it - a PetSmart for our 14-week old puppy. We had only had him for 4 days and I noticed that he had been biting at his legs. Afraid that he may have had fleas when we got him, I decided to give him a treatment. I purchased this thinking that something "natural" would be safer on his young skin. Put it on as directed and within 15 minutes, he started running around rubbing himself on the floor. We thought it was from the smell. Took him outside and he slid on the snow and ice, rubbing his sides/back/and pushing his head through the snow as well. When he continued acting this way, I gave him a bath. Behaviors continued.

I applied only half the recommended dosage to my dog for the treatment of fleas and ticks and was very glad that I didn't use more. Within a short time my dog became very stressed, anxious and very uncomfortable. I took the dog to the vet and brought along the product to show the vet. This product has a reputation for causing this reaction in animals. My question is "why in the world is this product still on the market?" Does Sergeant's not care that they are poisoning our pets? The store that I bought it at immediately pulled this product as soon as they heard my story... I'm sure there are a lot more!

I bought these drops at PetSmart. Ten minutes after applying one of my cats, Alice started acting lethargic and strange. I washed it off but so far she still seems ill. I hope she doesn't pass away like some of these other kitties. This stuff is terrible and I feel horrible for putting her through this!

Yesterday we put Sentry Pro on our German Shepherd dog according to the package directions. Appx 10 hours later he started showing signs of distress. Whining, unable to sit still, practically jumping up and down trying to lick and scratch his back. It was awful! He was obviously extremely uncomfortable. I quickly googled this flea medication and came across the exact same symptoms in the postings on this site. I quickly washed and rewashed his back with Dawn dish soap and gave him 25mg of Benadryl to help calm him down. Thankfully, it worked. I can not believe this product is on the market after so many complaints. I will never use another product by Sergeant's Pet Care Products, Inc.

My husband purchased the Sentry Fiproguard for dogs Plus IGR. My little 4 year old Yorkie, he's a little guy. My little guy began whimpering.. so I picked him up, and immediately the smell was awful - then - I noticed that my Yorkie's hair was everywhere, on my clothes, on the floor, falling straight off of his body :( Last night - he was going outside every 20 minutes to vomit and have diarrhea. He does drink water - but refuses to eat. Can't blame him. He had a high fever too, last night. Finally, at 5:00 a.m., he was able to sleep until 8:30 a.m. this morning, and so did I. He hasn't had to go out as much today but he is still feeling horrible. He won't eat, not even his favorite goodies. :(

Sentry Pro XFT - Our bichon became seriously ill after application. Applied it to our dog yesterday and spent all night trying to comfort her. Crying, yelping, spinning in circles, scratching, barking, etc. and this went on all night. Telephoned emergency phone number on the back of the package, and company rep said our dog seemed to be experiencing parathesia from an active ingredient in the product that some dogs react to. Rep recommended giving dog three baths and lathering her up using Dawn or Palmolive. Seems to be helping as she is now just beginning to settle down... 24 hours after application. I do appreciate the company rep who was patient and helpful in getting me through this.

I purchased Sentry Flea & Tick Squeeze-On for Dogs. I applied it, following all directions, to my 5-year old chocolate lab. Within 10 minutes of application, he began pacing and showing signs of distress. After four hours, I bathed him with warm water and Dawn dish soap and was preparing for a trip to the vet (during a snowstorm). I caught it early enough and he was able to return to normal. I would NOT recommend this product.

I don't usually buy over the counter flea medication for my dog. I get it from the vet or groomer. I saw fleas on my dog and went to the closest Petsmart and saw a large display of Sentry flea product for dogs so I thought it should be a good product. I followed directions and put the medication on the back of his neck down a small portion of his back. When petting him nearly a week later I notice he had big scabs And oozing pus. He is a Siberian husky with thick hair so I didn't realize this was going on till I really started examining him. It looks like the product was burning his skin. I took him to the Vet. This product is horrible and should be taken off the shelves. My vet has him on antibiotics, steroids. I will find out if more damage was done when his blood test comes back. I don't want to see another dog go thru this.

My sister applied this to both her dogs. Immediately they started shaking and foaming at the mouth. To where they began having seizures. Both dogs are in critical condition. TAKE THIS OFF THE MARKET ASAP.

Please be specific in your complaints about which product was used. Sentry sells a number of products. A lot of these posted complaints it's impossible to know what products to avoid.

After applying Sentry Pro XFT for dogs over 61 lbs my poor dog went totally crazy...started running and rubbing his body everywhere, was very anxious - so much that even snapped at me what never happened before. His body was twitching, I called emergency because it was night already. He is sleeping now after nearly 2 hours going crazy but I have no idea how he gonna feel tomorrow....I'm going to print the reviews and bring to Cabela, Pet Smart Petco and any store that sells that poison. Unbelievable is on the shelves, hate it!!!

I put Sentry PurrScriptions Plus on my 8 year old, very happy and healthy cat, three days ago. I only hope he comes back to this state as since the application, as per instructions, he has not been the same. He is scratching more than ever, howling like he is in pain and will not touch his favorite food! No fur loss on the back of the neck where the product was applied, as some have reported but it's only been 3 days. I purchased the product at the recommendation of my local PetSmart store. I don't know what to do!

About 30 mins after applying on my dog, he was very bothered, he couldn't settle down in one spot, he was whining, his back end was swaying crooked from rest of body. Obviously he was uncomfortable. I had to bathe him to get product off, but it absorbs into skin. DON'T USE ON YOUR DOG!

My husband bought this at PetSmart. (Guess it was cheaper). Within 12 hours of application, our 65 lb. pit-mix was clawing at herself and shaking uncontrollably. Gave her a quick rinse and applied some almond oil to her. After an hour, scratching and shaking were worse than ever. No sleep last night. Turned to these reviews for help. After re-bathing her with liquid Ivory soap, I decided to forego the recommendation to use Vitamin E, as the poison is apparently oil-based, and I was afraid of sealing the burning in. Decided to pour witch hazel all over her back instead, to soothe her skin. She seems to be resting fairly comfortably now after 24 hours of torture. This product is a disgrace.

I bought this product on Saturday of last week in Petsmart and on Monday, I applied it to my puppy and the same exact day, he started acting pretty weird, itching, and he looked really uncomfortable! That same night, he couldn't sleep, he was moving all around his cage and I was pretty worried. He wasn't eating well, not playing and obviously not being normal like usual. He was like this for 4 days until Friday morning, I saw on his back that he had a big sore full of blood and it felt like a ball inside. I got really upset and worried. I took him to the vet right away and then the doctor told me he had an infection and that he needed treatment right away. She said that product had burned his skin and that it was really dangerous.

We were searching for a low cost solution to fleas and used this product on our two cats, Jack and George. Within moments of application, both cats began salivating uncontrollably and running around like crazy! Then they seemed lethargic and laid down. It was a scary moment. We quickly began researching what would be causing this and how to treat it. It seems that cats are very sensitive to the 3 essential oils -- Peppermint, Clove, and Lemongrass. Thankfully our boys did not have the same long term effects and sickness as other cats had experienced. I have sent an email to both Sentry Pet Products and Petco to stop selling this product.

I put Sentry Pro flea medicine on both my dogs last night. About 45 min. later, my Yorkie started to throw up white foam. Agitated chewing at his tailhead. Whining and very shaky. I immediately gave him bath...no relief. Gave him 2 more baths with Dawn!! Some relief for him. My Irish Setter had ALL the same systems. Gave him 2 baths with Dawn. Some relief. They are about the same this morning!! This is not fair to my poor babies!!! We will another round of baths for them. Talked to Sentry hotline at 11 o'clock last night, was told it is an allergic reaction to the med!! Really!! How can they sell this medicine if it does this to poor helpless animals!!!! Everyone please beware of this product!!! I am so upset this us happening to my babies. Will NEVER use another one of their products again!! Rant over!!!

Sentry broad spectrum dewormer - After deworming my Dachshund she became very ill. She refuses to eat and just wants to lie around, which is very unusual for her. When she stands she is very wobbly and unsteady on her feet and after reading some of the reviews the product should have more warning information. I really thought this was a product I could trust. I am very disappointed.

I used Sentry Natural as it was cheaper than what I usually purchase but the smell is awful! I haven't gone to the vet yet but my cats and me are miserable. I will never buy this again.

I have used this company for years, and will never use them again... I purchased Sentry Purrscriptions Plus for Cats and kittens under 5lbs for my 3 cats. I put it on them Saturday December 27th around 7:30 am. The next morning I found two of my 3 cats seizing uncontrollably. I took them to the emergency vet where he gave them Valium. One of my cats was up and around but still shaking. My other one Tig however seized until 8 pm that night. He is still shaking a little today. The following morning after washing off my 3rd cat who was not showing any signs of being affected at around 4 30 am I heard a hissing and loud meowing almost like a cat fight. When I got up to check on her I found her on the floor violently seizing, to the point of attacking. We got her to the vet who ended up keeping her overnight. She didn’t come out of the seizure until the following morning.

Advantix 2 has been our choice and it works. But we tried Sentry Purrscriptions Plus as an alternative because it was a little cheaper. Says it kills fleas, eggs and larvae within 12 hours but it sure didn't! Gave the cat a bath 2 days later and it still had fleas. This product DOES NOT WORK!

Sentry flea n tick - I used this product on my dogs and they both broke out with a really bad rash, sores and hair loss the next day. I took them into the vet and they both had infections, needed shots of medication and advised to take the product back immediately. Petsmart refused to take the product back even with the dr.'s recommendation.

We applied this product two nights ago and our dog immediately began twitching, itching, and experiencing clear discomfort. The next day we noticed he had severe muscle spasms and was unable to lay down without all four of his paws convulsing. We took him to the vet and gave him 3 consecutive baths with dish soap but he is still feeling miserable. He cries out of pain and is unable to even lay down to sleep for the night because of the extreme discomfort. Even with the use of Benadryl he is still not doing okay. DO NOT RECOMMEND THIS PRODUCT FOR ANYBODY. The well-being of your dog is not worth the discounted price. We are appalled that a product like this sold in widely known pet chains such as PetSmart. We cannot imagine how a product like this passed any sort of federal inspection and we want this product OFF ALL SHELVES.

I purchased this product online for my two cats, and the type I purchased the one used for cats 1.5lbs and over due to health issues with one of them. It’s now been a month since we first applied this product. However my cats are still experiencing fleas, as if NO treatment had been done. I went to check the expiration date of the product, but was unable to determine the date, so I went online to search to see if I could locate it, but had no success. Not even the SentryPetCare.com site offered this information. Due to this I can't say if this product 'works' or not as it may be an expired product, where the effects would be limited to non-effective. The only thing the site states is that in proper conditions of storage it has a life expectancy of 3-5 years... and naturally if the storage wasn’t ideal it's shortened due to this.

I used to use Frontline on my cat, Trixie, but the girl at the pet store said Sentry was the same thing except cheaper. Now she won't eat and when she does she vomits. I agree the smell is awful and whereas Frontline drys quickly, this stuff stays on for days. She has FIV so just hope it hasn't caused any irreversible problems. She is 12 and been healthy regardless of her FIV. I'm horrified to hear of others pets dying and you have my condolences.

I purchased Sentry Natural Defense for our kittens and cats mainly because the product claimed it was all natural and good for kittens and cats of all weights. I wish I had never bought this product! The very next day, one of our kittens' fur was gone at the application point. I immediately gave her a bath to get the Sentry product off of her. I wish I had washed it off my other kitten the same day. The first kitten to show reaction to this product has a bare area on her back that does not seem to be healing. A few days later our other kitten can no longer potty on her own, eat or even drink on her own. We took her to our vet and he gave her a steroid shot and gave her a bath to wash the product off of her. We were too late though. Our sweet kitten now stumbles around in circles and the vet thinks she has neurological damage. Our vet has also given us an IV bag to continue flushing her system throughout the weekend. Our sweet little kitten has no control over her legs and just stares into space. She does not respond to us and we have been told she may not survive. We are heartbroken!

Used this spray on both my cat and kitten. Worked fine on the kitten but my cat has been foaming at the mouth with it. Thought maybe the first time I used it he got into something but used it a second time with the same problems.

We noticed sores under his neck after about three weeks after we put it on. We immediately removed the collar. It has gotten worse and has been off for a week now. We are taking him to the vet tomorrow. I just pray that no other cat has this problem. From the photos I've seen on the Internet there have been quite a few. Something needs to be done about this.

WASH IT OFF WITH DISH SOAP NOW!!! Last night at around 9, I give my pompom, Cash, a regularly scheduled bath using say shampoo since day one. After I dry my little guy off I decide to give him his first flea treatment using sentry flea drops. I follow the directions to a tee, about 30 to 40 minutes later I hear my pompom in the bathroom crying and whining. I go to the bathroom and there he is looking at me mouth covered in foam. Being the person I am first thing’s first... Google. I immediately see this forum, read a few post, wash my pompom with dish detergent, give him a second bath with his regular shampoo and by the time I finished the foaming had stopped. Its 3 p.m. the next afternoon and he back to his regular self, jumping and energetic. Some people aren't so fortunate so the first thing I recommend you do is WASH IT OFF IMMEDIATELY.

I wished that I had seen these reviews last year. I bought the Sentry Flea treatment for my two 13 yr old cats. The first thing that I noticed was the strong chemical smell when I applied the product. I had thoughts of washing it off. I wished I had because less than 72 hrs later I came home to find one of my cats dead. I felt and still feel guilty for cutting my poor Felix's life short. Oscar and I still miss him so. I only buy all natural products now.

Wish I had read this board before purchasing Sentry Pro XFC. My wife bought this product at Petco to treat a new cat we brought in our home. We have 2 Dogs and 2 other cats in our home so my wife bought 1 (3 pack) box each for Cats and dogs. My cats have not had any reaction to it (12 hours and counting), but within minutes of applying, our Dog (a Shih-Tzu) began itching and licking uncontrollably and having weakness in her back legs. We took her upstairs and gave her a warm bath with Dawn dish soap, and her symptoms improved somewhat. This morning, she is still shaking and licking herself, so we gave her Benadryl and she seems to be okay. NOW.........My other dog is having some bizarre behavior (Crying and moaning), so my wife is upstairs bathing him. This product is DANGEROUS!! Do NOT use it on your beloved pet.

My little girl got the sweetest kitten for her 2nd birthday. We had her for about a week when I noticed a few fleas. I bathed her with dawn dish soap and then applied sentry medicine to her neck area, as directed! The next day we woke up to the skin on her neck FALLING OFF!!! She became lethargic and started walking sideways. I bathed her again with the dish soap to get the crap off of her, but I was too late. She lost bladder control and started having seizures 2 days later. Her neck is now bare and scabbed but THANKFULLY the vet said after a ton of fluids, she should recover fully. Bathing her as soon as I noticed may have saved her life. I will NEVER recommend this product to ANYONE! IF you choose to use this product, it is my opinion that you have just signed your pets death certificate, but that's just my opinion.

I applied Sentry Pro XFT to my Yorkshire terrier this morning, BIG MISTAKE! My poor baby immediately started acting out of sorts, whimpering and pacing all around the house. I was about to leave the house to run some errands, but thank the dear Lord an angel was sitting on my shoulder telling me to wait a minute and watch my dog a bit longer. The reaction I was seeing wasn't normal. After 10 mins of applying this deplorable product to my baby I had the instinct to wash it off of him immediately! I bathed him twice with mild soap and cool water because the site of application was burning up! I hope that the amount of time it was left on his skin and two baths have completely removed this product from my dog. I am partly to blame because if I had searched this product online I would have seen the bad reviews and walked away from this garbage! This product was recommended by a Petsmart sales associate over another brand of flea and tick medicine. I wonder why Petsmart sells this junk? So disappointing...

I purchased Sentry PurrScriptions Plus at Petco since they were out of biogard which I used on one of my cats. On the other four cats I used the Sentry over a week ago and not only are they still scratching, but it does not seem to be working. My other cat did not get the fleas back and since she is white I do not notice anything on her nor is she scratching. The house has been cleaned, vacuumed and all the bedding has been washed. This product should not be on the market since it does not work. I called up Petco and was told by some customer service person that fleas die after they bite. Stay away from this product and I am truly sorry about the animals that have died. I feel for your loss since I am an animal advocate at night on facebook. I did use this product on old cats, one 15 and one 16 and am happy that they did not become violently ill. God bless.

I rescue a cat and used Sentry Flea Control. It took off the fur where it was put on. I feel so bad. I was just getting her to trust me. And now I have washed it off but the day after she just lay around. She would not even get up for her treats. I called the Vet and they said wash it off with Dawn dish soap. I pray it has not done any damage to her. They said it could. This stuff should be pull off the shelves. I got it at Petco. I am telling them about this. This was what the store recommended. Do not use this product.

I sent my husband to pick up Advantage for flea treatment on my 10 pound chihuahua and some idiot girl at Petco convinced my husband to buy Sentry pro toy. I won't get into how mad I am that he didn't get what I said to get because now I'm dealing with my best friend buddy suffering and has become lethargic and disoriented. I am at the vet right now. My buddy is a happy, singing, jumping and even smiling chihuahua.

My 65 lb boxer suffered about an hour after applying the flea and tick treatment on her skin. She had uncontrolled itching irritability and issues with her back legs. She was restless and uncomfortable and would lose her balance easily. I applied this because it was recommended by Petco and I should have done my research before giving it to her. We ended up at the vet and she has burns on her skin from this product. NEVER again! I'm back to my tried and true Advantix product.

I purchased Sentry flea and tick medicine for my cats last month put it on all my cats. Now we have a full blown flea infestation and the ticks wouldn't stop biting them. This product should be taken off the market. They should have to pay for a whole house treatment. I purchased this product at Tractor Supply.

I purchased Sentry flea medicine for my 3 cats and 3 dogs yesterday afternoon and administered the medicine to each of my animals around 4 pm. This morning I was awoken by a strange sound. I got up and let two of my dogs outside, I then returned to my bedroom and noticed my cat, Sugar, laying by the wall and something didn't seem right. I nudged him with my foot but he didn't move. I turned on my bedroom light and kneeled down on the floor next to my cat. He was panting and foaming at the mouth. He tried to move but was having trouble standing up. I noticed that there was some blood mixed with his saliva. Before I could get dressed to rush him to the vet, he passed away. I am heartbroken and outraged that this product is still being sold in pet stores!!!! I contacted the emergency medical number and they apologized for my loss and took a report to send to corporate...REALLY!?! That's all they are going to do... How about stop selling a product that poisons and kills animals!!!! Please please please do NOT use this horrific product and share this information with friends and family

I have a mixed breed dog. Half lab half pit, he weighs about 40lbs. I normally use K9 Advantix II but in my town it's only available at the vet and it is expensive so when I saw Sentry dog and tick I thought I would give it a try. BIGGEST MISTAKE. Have it to my dog and in the first hour his itching was horrible. He doesn't usually have an issue with fleas because I use Sergeant's shampoo and it does great. I mainly bought the product for the ticks.

My comments echo the other displeased and distraught consumers of this product. Applied to my husky and the next day she was biting and scratching her back where we applied it. She was sensitive in that area, growling and running away from us if we tried to touch her there. For about an hour she seemed to be hallucinating... Looking for things that were not there. We gave her a bath and it got to get better over the next few days. Stay away from this product. Pay more at your safe products at your vet's office.

On Friday I applied Sentry Fiproguard flea spray to my 7-month-old cat. Her leg seemed SENSITIVE TO TOUCH Friday night. I thought she might have injured it herself, but then on Saturday she was worse. She BARELY MOVED all day unless she had to, and DID NOT WANT TO BE TOUCHED. I thought it might be a skin reaction to the treatment and figured I'd take her to the vet if it didn't improve. This morning (Sunday) she was having TROUBLE BREATHING and LOST CONTROL OF HER BLADDER. We removed her from under the bed and brought her to the living room near the litter box. While being held she STARTED TO CONVULSE and THEN DIED.

Please DO NOT use this product on your dog or any animal for that matter! I bought Sentry Pro xft from PetSmart because they were out of BioSpot, which is what I normally buy for my Pomeranian. The sales woman recommended it, so I purchased it and applied it on my dog that night. About an hour later, he started pacing back & forth & acting very agitated and anxious. I always notice when his behavior changes - he started having these little 'twerks' like he'd jump up, as if he was getting a shock. Then he started gnawing at his butt and groin, so violently, it was very scary.

Used Sentry FiproGuard on my small Jack Russell Terrier and within an hour after applying it he was beginning restless and itching and whining and not wishing to lay down at all. There is no warning in or on the box stating all these symptoms can happen to your pet. I did bath him within a couple of hours to see if that helped but he still was restless and itching and whimpering.. Thinking this product needs to be taken off the market, from what has happen to my dog and reading the same thing about many, many other people, let just say I am not very happy and would love to talk to the head of this company and tell this person what I think about it. I will return to the other brand I always used in the past and had no troubles at all with that one.

This product is poison. My 35 lb beagle is now suffering. I put sentry pro xft on her at noon Saturday... had to rush her to the hospital on Sunday for violent body shaking and scratching. They gave her a shot of benadryl and bathed her with dawn detergent. It is now Tuesday and she is still shaking and is now having muscle spasms. If your dog is suffering from this god awful poison...bathe your dog immediately with dawn dishsoap, give them benadryl 2 or 3 times a day, put vitamin e on their itchy back and neck, and buy them a thundershirt. The thundershirt is the only thing that allows my dog to rest and sleep without itching or twitching. This product needs to be taken off the shelves now. I bought it for the price... but now I'm over $200 down the drain and the one I love the most is suffering. I'm spreading the word around every pet store I can. Poor innocent pets.

Well, can't say I'm surprised that I'm upset with failure of product after the countless negative reviews I read! Hubby picked this up at the suggestion of a PetSmart employee (prior to my reading reviews), after our indoor 12 year old male cat (17+ lbs), for the first time ever, was recently found to have fleas. (Totally skeeved me out, especially since we're uber-clean, and have 3 small children; one of which had some in her hair, and was bitten several times, after we found some in her room, where Oliver had recently visited.)

We applied Sentry Pro XFT to our 2 year-old, 53 pound lab mix this morning, with dose for 40 to 60 pound dogs. She had immediate and severe negative reaction, including frantic and incessant scratching, running around frenetically (unusual for her), panting and shaking and crying out of obvious pain. I have used other flea products by Frontline on other pets, and never had a problem, so was surprised and very concerned. When her extreme discomfort continued, I wiped her skin with a cloth to remove the product. When her scratching and crying persisted, I followed the box directions and washed her with soap and lots of water. The symptoms continued, with constant scratching, jumping about out of pain, whimpering. I called the hotline number on the package, and was told there was "no health concern", but to wash her again with dish soap and apply cold compresses and vitamin E, and wait 24 to 48 hours for the symptoms to subside.

I purchased Sentry with Fiproguard flea control for cats at my local Petco. I asked my husband to administer this stuff to our cat and to give one to our tenant downstairs for his cat. This morning, I googled this product and found these reviews. I'm absolutely horrified. I immediately called my husband and frantically told him NOT to use this garbage on the cat and to get the other vial back ASAP from downstairs.

About a month ago I put the Sentry flea and tick for xl dogs on my 100-pound black lab in mid-afternoon and by the end of the night he was rubbing up on everything that he could to try to itch it. I washed him the next day and he seemed much better, not trying to use everything as a scratch post, but he still continued to itch himself, which he has NEVER done before, behind his ears and his butt. I thought maybe there was still some on him so I gave him another bath and still the same thing. It didn't seem like much of a problem, so I thought I would just let him itch every now and again and that was it.

We purchased Sentry Sure Shot De-wormer for cats and kittens to treat our four cats for worms. After 24 hours of administering this so called medication one of our cats had become very sick - vomiting, labored breathing, diarrhea, and laid on the floor and died. We thought maybe it was a coincidence until only a couple hours later another cat treated lay on the floor lifeless and died. The other two cats seemed to be ill but not as ill so we kept an eye on them until the next day and noticed they refused to eat, drink, and started showing symptoms the other two cats had displayed prior to dying. We quickly called and rushed them to the vet where they were diagnosed with being poisoned and the only treatment was fluid to try and flush their bodies of the toxins. After receiving treatments they seemed to perk up a bit but only to take a major turn for the worse the following day when we noticed yet another one of them lying on the floor completely lifeless, barely clinging to life.

Put the flea drops on my dog and instantly hurt her and her left side became paralyzed for quite a while. After it subsided I checked her next day and she still has fleas. Waste of money. My dog got hurt and now I still have a flea problem. The people and PetSmart didn't even know where the product was so I got no advice. The stuff needs to be pulled from the shelves immediately and we need to be reimbursed.

Sentry Fiproguard Max for dogs - I used this product on my sweet 3 lb chihuahua and it had a horrible outcome. After losing her appetite she would vomit, was very weak and unable to stand. I took her to the vet and she said there was nothing they could do for her. I brought her home to die. She passed away in my arms at 2 in the morning. I have contacted the company, I was also featured on a local news station and I have petitions circulating to get this product removed from - No other animal or family should ever have to go through this!

Sentry tick & flea squeeze-On for dogs - My dog died from this product. I took her to the vet when I noticed an issue. About 24 hours later she was dead. I took her to the lab where test were performed. It was due to the product. They offered $65.00 toward a new pet and some money toward the medical bill. About $200.00 total they offered. I just want the label changed. It said nothing about my dog could have an adverse reaction and die... ugh. Heartbroken... I do have photos and the reports on file.

Sentry Fiproguard Max harmed my cat. After application, she became lethargic and was averse to touch. She was experiencing pain at the application site and would not stop licking herself. Her breathing was rapid and since she already suffers from asthma, I was very worried about her. I was shocked to see all the negative reviews online and horrified to see that this product seems to kill animals on a regular basis!

Sentry fiproguard for cats - Simply did not work, you get what you pay for!! 1st application 1 month ago today, the cat still had fleas brushed and combed him every day always got at least 3 or 4 fleas last night 15 fleas!! applied 2nd tube this morning and brushed him tonight 10 very active fleas for my effort!! Needless to say next month will try another brand or a trip to the vet. House has been vacuumed top to bottom, bedding washed, cat's bedding been washed.

Second day after application, both my dogs are stumbling around losing use of their rear leg. The one I assume they used to scratch like crazy at application site. Toxic, take dogs to vet asap! I cannot afford, I will contact company. I'm furious! They have sores in a few areas. Lethargic. I'm going to do what I can to get this off shelves! I encourage all to do the same.

Sentry fiproguard cat flea drops - They don't work whatsoever. They didn't even make the fleas sick, much less kill them. I comb him daily as well and am still getting healthy fleas off him 3 weeks after applying the drops. I'm going back to pet armour drops. They work (I didn't have time to run to walmart for them).

The employee at PetSmart told me the product was equal to the top brands. My poor dog was still itching and has not stop. What a waste. He still has fleas.

I purchased Sentry from Petco ten days ago. Twenty-four hours after applying it as directed on my kitten, he was unable to walk and having convulsions. He also had foam around his mouth. After speaking with an emergency vet, I was advised that he had been poisoned. I bathed him in Dawn but his shaking got even worse. Fortunately, I was able to get him to the vet. I have been told he will be fine. His system needs to be flushed, though, and he will have to be given muscle relaxers. This flea prevention medication, according to the reviews on this website, have paralyzed or killed several pets. DO NOT BUY SENTRY FLEA PREVENTION! YOU COULD BE MURDERING YOUR OWN PET!

I purchased this product at Petsmart yesterday (the clerk I spoke with had no idea what hot spots were or what any of the products did) in hopes of clearing up my dog's hot spots on her underbelly (I have a 5-yr old Golden Retriever/Boxer mix) and applied as directed. Within an hour she was vomiting and foaming at the mouth, unsteady on her feet and just plain miserable for over 4 hours until she went to sleep after what I assume was just from sheer exhaustion. I re-read the package for the Hot spot treatment and there are no warnings or anything regarding allergies or what to do in case of adverse reaction to the medication. I just wish I'd googled this product first and read these stories before subjecting my dog to the pain and torture that she had to go through last night. Please... please.. Do not use this product on your animal and thoroughly research the product and ingredients first before using on your pet.

The sales associate at PetSmart convinced me to buy Sentry Fipromax Guard for my cat to protect her against ticks. Upon application, the cat immediately began to vomit and moan in pain. All of the fur at the application site fell out, and my cat was left with painful blisters and oozing chemical burns on her neck. She remained sick for the next two weeks, barely able to eat or drink. Our house is now overrun with fleas. TL;DR: Flea drops cause chemical burns and toxicity issues for weeks. Did not kill fleas.

Days after purchasing this and applying it to my dog and cat, my dog became paralyzed from the waist down and after many tests and very heart wrenching days of watching him suffer, I had to have him put down. At the same time I also applied it to my cat who disappeared the same time my dog became paralyzed. Never to be seen again. DO NOT APPLY THIS TO ANY CREATURE!!

So I just treated one of my cats mere moments ago. She started running in circles and foaming at the mouth. I washed it off as quickly as I could. I'm hoping she will be ok. She was a neighborhood stray (the owners kicked her out and then moved away) and my daughter kind of adopted it after hers was hit by a car. Reading the other posts here, I'm scared that we may lose her now. How do I tell a 5 year old that both her cats are gone? The lady at petco ranted and raved about this product, saying that it didn't have one of the ingredients that frontline did so it was safer. I would just need to treat 3 times in 28 day intervals. Never again. So help me if this cat dies.

They said he had pyrethrin poisoning. Why would they sell such a product?

I bought Sentry PurrScriptions Plus, for fleas. I Also sprayed my rugs... This product did not work at all. I had to go to the vet $$$$. They gave her a pill to kill fleas in 15 minutes and by Front line. That was all I ever used on my dog. It always worked. I READ THE REVIEWS... This product should be taken off the market. 288 customers that had real serious problems, "THANK GOD IT DIDN'T HAPPEN TO MY BABIES."

I have a 38# basset/pointer mix and have always kept up with his flea and tick treatments (frontline). I had him in for his 6 month checkup and vaccinations just yesterday and he came out with flying colors. The vet said he will probably be tired the rest of the day because of the shots, which he was. This morning he was up and back to his normal playful self, so at 7:30 I gave him his flea/tick treatment. At 10:30 he began shaking and by 11:00 was hardly able to walk without stumbling. I immediately called the vet, but they were not able to talk to me and said they would call back. After about 20 minutes, noticing that his condition was getting worse I just decided to take him in. They are giving him a hot bath to get this off of his skin and anti-seizure medication and monitoring him for a couple hours to make sure he is okay. I called Sergeant's (Mfgr of Sentry) to log a complaint about this product and will be returning it to PetSmart for a refund.

I want to give no stars, but that is not an option. We bought Sentry Natural Defense (spice scent) and applied as directed to my 14-year-old pug. The smell was overwhelming and I should have washed off immediately. Several days later, he had a seizure in the middle of the night that lasted one to two minutes. He was never the same after this. He had loss of balance, vision, tremors, restlessness, trouble sleeping, crying, and labored breathing. His breathing became progressively worse, and had to let him ago less than a week later. My wife and I are so heartbroken. :(

I used this medication on my cat and a few days later she could barely walk. It started with her being lethargic, twitching when you touched the application spot on her neck, and only being able to take a few steps before falling over. I took her to my vet and they washed off the medicine, ran blood work and X-rays, the whole work up. He told me that she was definitely poisoned by the medication, not that she accidentally licked it but that it had gone through her skin and poisoned her. She lost all the hair on the application spot and still had a hard time walking.

Bought fiproguard plus at petsmart as an alternative to frontline price. I used the 45-88 lb pack on my young adult siberian husky. Awful mistake. My dog seemed immediately irritated as I applied the product and was very lethargic for two days and seemed uncomfortable. He was restless and would not lie down for very long. Plus he avoided anything that had the fiproguard scent and would hide. Do not use this product and spend some extra money on a reliable and proven brand like frontline.
