Sentry Pet Products Reviews

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.

I used sentry products, bought at a high price pet store, paid much, used it on my animals and they got very ill. Also their products do not work, thousands of dollars in pet bills including 2 deceased pets. Do not buy!!!

Advanced owner of cats and dogs. Purchased Sentry Purrscriptions Plus. Used on all 8 of my cats. They remained outside in their safe, stockade fenced yard with 250 sq. foot Funhouse. The next morning, my year old adopted male, Sprout, was found deceased in his bed. Not a mark on him. Pained look on his face. I truly believe this product needlessly killed him. AVOID. PLEASE.

Applied Sentry Pro as directed. No warnings about severe allergic reaction found in large amount of dogs that have used product. My 102 lb black lab starts coming out of his skin. Can't sit, lay down, panting, whining - now going 8 hours - emergency vet say not a lot they can do. It has to run its course. My dog is suffering and there's not a damn thing I can do about it. This product should come with WARNING clearly marked to let people know this could happen. If you look on the Internet there are hundreds of dogs having same reactions. I now have to tell my children we cannot go on vacation they pack for and think we are leaving in morning. Thanks Sentry great product!!!

Sentry PurrScriptions Plus Squeeze-On for Cats and Kittens - My boyfriend applied this product on my cat Sammy who is 5 years old and our other cat who is about a year old. My cat Sammy of course didn't like it very much and took off outside. A few hours later I called for him to come inside but he was acting strange, not really wanting in the house, and was kind of hyper. When he did come in the house, he did not eat, which is odd for him. He also did not want to be touched, anywhere, another odd things for him. He was jumping on things, could not get comfortable, just up and down. He was bleeding on his skin on the site of the area the medication was applied to, not a lot, it was more like a surface type bleeding where the skin had been burnt. His neck and back was also having muscle tremors and it appeared his stomach was pumping up and down faster than normal.

I thought I would share my story since I have yet to read about this exact experience. I have always noticed my dog acting odd after applying the Sentry product (bought from BJ's Wholesale Club). He will obnoxiously rub all over the furniture and the rugs for the next day. I thought this was just part of the process and kind of shrugged it off. Well tonight I applied it, then took my dog out a couple hours later. He started rolling all over the grass, ripping at it, then jumped up, yelping and in a frenzy, and bolted down the street! I had to load my children in the car, at 10:30 at night, to find my frightened dog crossing a major road half a mile from our house. Now, while I can't directly connect these two incidents (the applying of the medicine and the running away), my dog NEVER runs away and acts like this. He is a mess right now. Just thankful he was not hit and killed. Please, PLEASE watch your pet closely after using this stuff. As for me, I am returning to Frontline with which I had no issues.

I went to Petsmart to pick up some Frontline for my cat. The only thing left on the shelf was Sentry so I purchased a 6 pack. I gave my cat a dose & she is now scratching like crazy, very lethargic & has lost her appetite. I am bringing her to the vet in 2 days to see If there is any relief I can give my baby. I wish I would have read the reviews first. I have not seen ONE good review. Please take this product off the shelf!!

I used the SentryPro flea and tick control on my dog last night. It was the most horrible experience. Within a very short time she was extremely agitated, panting and unable to get comfortable, very stressed out. It attempted to wipe it off of her and then called the emergency number on the package. They were very helpful with their advice. Told me to bathe her in Dawn, try cold packs and vitamin E on her skin. I was up most of the night with her. I didn't even use the whole tube on her and am glad didn't.

We applied Sentry Fiproguard for Cats to our 1 year old, healthy cat as directed on the package - in fact I put it up a little higher on her neck, rather than between shoulder blades as instructed so she wouldn't be able to reach around to lick it off. We applied it at night and by morning she was twitching all over and becoming lethargic. We took her in to the Emergency Clinic and they were able to save her, but they said she wouldn't have made it without intervention. It cost us $538!

I purchased SentryPro XFT to treat the fleas my dogs picked up on a walk through our new neighborhood. My 10-year-old Schnauzer JJ and 5-year-old Yorkie Chloe had never had fleas when we lived in the city, but due to financial issues, I had to move out of town. The rent is so much cheaper. It's well worth the commute, but now I regret it because of the suffering my babies are going through. As I said, money is tight, so I was delighted to find a less expensive option than Frontline and assumed if Petco was selling it that it would be safe. How wrong I was.

I have 5 cats and a dog. Always used Frontline. Petco did not have Frontline for cats and told us to try Sentry PurrScriptions Plus. All my cats lost hair around back of neck... almost all cats Lethargic one day later. One cat can hardly keep her eyes open and will not eat. She runs away from me every time I try to get near her to wash product off. Never had this problem with Frontline. I hurt my animals with this product. I will never use again and it should be taken off the market. I have read so many complaints. Should have reviewed product before use. I now pray my cats will come through this and will be okay.

We applied this to the back of our three-year-old cat's neck. We have recently moved to a coastal area where fleas are a problem. It was very oily and she immediately tried to get it off, although she could not reach the back of her neck. Since that time she has become agitated and jumpy and has twitches in her back legs and hitches when she runs. We are taking her to the vets today. They said it was probably an allergic reaction to the medication, but now I am reading comments from other people with problems and think she has been poisoned by this product.

I am a part-time caretaker to my neighbor’s cat, Cody. We discovered Cody had picked up fleas. His owner purchased Sentry PurrScriptions Plus. I treated Cody with the product according to the directions. He acted like it burned. I noted the product was spreading looking very oily. I figured he just didn't like the wet feel. Within an hour he started vomiting and had dark, nearly black, diarrhea. He acted like he was in pain. Hours later I tried to get him to eat but he refused which is very strange. This poor guy was horribly ill. I washed him off with Dawn but he was still oily. He is still oily today and it has been 5 days since he was treated. He seems okay now but time will tell. He has always been healthy until this product poisoned him. STAY AWAY from Sentry Please! This product was recommended by the staff at the store.

I, like everyone else, saw this product in Pet Smart and figured that they would not sell something that was not a product that had been tested and was reliable. I was wrong. Within 10 minutes of applying this product, my dog started twitching and scratching. He seemed to anxious and was trying to scratch in places he couldn't reach. I took him to the vet who gave him a cortisone shot. This helped somewhat, but not enough to make him comfortable. He refused to eat, even his favorite snack. Two days later he has eaten some of his favorite snack, some of my special K Cereal (which he loves). He is as active as he was.

I used SENTRY EARMITE-free EARMITICIDE FOR CATS on my 5 cats for ear mites on Sunday night. I purchased the product at Petsmart. All of my cats were given the medicine as instructed. My Siamese cats' ears are bright red and all her fur has fallen off of both the inner and outer ear. I noticed this on Thursday night. I have 2 large black cats and tonight their fur is getting bald spots on the tips of their ears. Has anyone else used this product on their cat(s) and had similar problems?

To all of you, I totally agree. Like many of us, I went the less expensive route because I was in PetSmart (yeah right) and purchased this product on a whim (usually Frontline). After a few minutes, my boy Floyd was twitching and scratching giving that "what did you do to me?" look. He spazzed out for a day. I gave him a bath and a Benadryl and that seemed to help. Still fleas! He was a hot mess in the morning and he was a scratching pup. I called my vet and asked if I could give him a dose of Frontline right away and she compared the chems from this ** product and said OK. I'm happy to say after 2 days, he is back to normal. No itchy and scratchy with a look of "thank you pop and Frontline". I'm not an advocate and don't work for the co. but that is my tale. My boy Floyd said "Don't skimp out on me again pop" (the way that dogs do)... It's a helpless feeling being a pet owner watching this happen. SHAME ON HARTZ. FYI I found out the chems they use in this crap are ancient chems from the first days of flea treatment. Delivered in a model T Ford.

ATTENTION PET OWNERS!!!!!!! Do NOT use this product on your pets!!!!! This is a picture of a Husky that came into the vet office where my friend works. The owners put this on their pet 2-3 days ago and this is what happened. Be VERY careful what flea/tick protection you use on your pets!! NEVER buy an over-the-counter treatment! If you've used this or something like it, seek veterinary care for your pet ASAP.

With all of the rain and hot weather this summer we've had a big concern for a larger amount of ticks moving into our area. I have a 14 lb Lhasa-Poo who is regularly treated with the 1800petmeds.com brand monthly flea drops and it's worked great at a very reasonable price. Concerned about ticks, I instead purchased Sentry FiproGuard Plus IGH(?) for his appropriate rate. Being part poodle, he can be a little jumpy and barking easily during the day but not to the point where he becomes an annoyance. After putting the first dose on him, I started noticing how agitated he became over the next 24 hours. He takes prednisone on a regular basis (5 grams day) for skin allergies he was born with. He's only fed a 100% grain free diet, Joint/Vitamin Chewies and an herbal supplement on his dinner to try to compensate for the immune system compromises that the prednisone affects.

I applied Sentry Fiproguard Max to my 3-yr-old kitty Rosa EXACTLY AS DIRECTED (who by the way had a yearly exam just two weeks before and given a clean bill of health). I even watched her like a hawk to make sure she didn't try to lick any of it. She seemed fine for about 4 hours playing in the yard. Then I made her come inside because of the heat. Everything went downhill from there... She went to sleep and only got up 1 time, used the litter box and then started acting like her back legs didn't work and vomited foam everywhere, wouldn't eat anything. Called the # on the box. Said to take her to the vet. Before I got her in the car, she was dead - 23 hours after application.

Times have been tight and we bought this product from PetSmart to help with fleas. Within a few hours of application, our cat began twitching and walking funny. We thought she might be cold and decided to keep an eye on her. 7 hours later, in the middle of the night, our cat fell off the coffee table and couldn't use her back legs. We washed her with Dawn dish soap and saw some improvement and took her immediately to the vet when they opened this morning. Many tests, fluids and bloodwork later, she still does not have use of her back legs... praying desperately she is ok. I WILL NEVER BUY THIS PRODUCT and will do everything I can to warn others...

We put this Sentry product on our 1 year old healthy cat. Two hours later he was drooling, spasming, twitching, it was the worst thing we have ever seen. We called the emergency number on the box and after giving all of the info requested she told me it could be toxic to take him to a vet but she needed more contact info first. When she did that I hung up and immediately started bathing him. After ten minutes of bathing he seemed to come out of it. Five minutes later he was doing it all over again much worse. Our cat died that time. Do not ever use this product on any animal and Sentry should remove this product or all of their products from the market. The pain and suffering of our poor cat and the mourning of his death by our children has been heartbreaking.

Applied to my dogs within an hour, both dogs were yelping. Their ears were bright red. I washed the product off. It's been 6 hours and both dogs seem to be in discomfort and anxious.

I purchased the topical Sentry Purr for my cat. The fur on the nape of neck all fell out and left him with a red irritated bald spot. I took him to their vet today as the spot has begun to heal and Dewey is dropping clumps of fur all over the house. I spent 300 bucks at the vet today to fix my cat from this stuff. I was told it is a pesticide and enters into the cat's bloodstream. Worse part of this also besides my poor cat skin, fur, and bloodstream is that my baby still has fleas!!!! This stuff is horrible. It hurt my cat and did not even touch the fleas! Just a horrible product!

I am astounded at all thee reviews for this product and how much our poor dogs have suffered. I placed the Sentry on my 1 year old terrier mix last night and he is still behaving erratically more than 24 hours later! I even took him to Banfield - at Petsmart where I bought the product. Today - with a photo of the product asking if it could have caused his nonstop pacing and twitching, they said - no! It is probably a big bite of some kind. The poor thing will not stop digging, scratching and crying. I have bathed him 2 times with dawn but it is not working. I am so upset. I will never buy this product and I hope that he will come out of this ok.

Within 30 minutes of applying the topical treatment my 2 yr old 28lb Beagle became very agitated and started scratching at the application site and trying to bite her back. I thought her agitation would subside after an hour but it became worse. She kept me up all night pacing and scratching until I finally decided to bathe her at 1:30 am - 5 hrs after the application. It seemed to help and she was able to sleep a little. I called the vet first thing in the morning and she told me to bathe her with a de-greaser (Dawn). I have since bathed her two more times with Dawn.

I went to Petsmart two nights ago with my two dogs, a Chihuahua and Chi/Pinscher mix to get them flea and tick meds for the summer. I normally use Frontline and have never had any issues but this Sentry was a bit cheaper so I made the big mistake of buying it. My dogs have been itching, biting, crying in pain and snapping at me when I've tried to comfort them which has never happened. I just got home from work and rechecked their skin under their coats and it is red and inflamed. I cannot believe that they still sell a product like this after so many people have had issues!!!

Pink was poisoned by the shampoo which is toxic. I called and demanded they pay the vet bill. I got an ignorant "student" who pretended by be a certified DVM. The emergency hotline is run by "students" who are not licensed to give out advice when pertaining to an emergency vet situation nor should lie and pretend to be a certified DVM. Beware. I too picked up this "poison" at PetSmart and it did poison my cat.

My wife and I purchased the Sentry flea and tick droplets from Pet Smart. We applied it to our dog and within an hour of putting it on, she was going nuts. She was rolling around on her back and rubbing her ear on the carpet and outside in the grass as if she was trying to get the stuff off of her. That evening the dog paced the bedroom all night long, she was extremely uncomfortable and was unable to settle down until around 4 am. When I came into work I did some research on the product which brought me to this consumer affairs webpage. I was shocked to see the number of people having issue with this product. I am upset at the fact that Pet Smart would sell such a product given the fact that they pride themselves on proper care of animals. We used a dry shampoo to get as much of the stuff off the dog and we took her to the groomers today so she could a thorough scrub. This stuff is toxic and needs to be removed from the shelves IMMEDIATELY!

Sentry Pro XFT - I applied the proper dosage to my two small dogs (approx. 15 lbs. each). The product does not work. They both still have fleas. I got online to check this out unfortunately after the fact and am horrified at the reviews. Why is this on the market? I'll continue to get the word out until it is taken off.

I bought that repellent from Petco and put on my dogs. Next day I had our Boxer Brutisk at the emergency vet. Over $500.00 later and it looks like she will be ok. My dachshund Manfred not so lucky. He is having a blood transfusion as we speak. He might not make it through the night. It’s well over $2000.00 so far. I am shocked. I can't believe I put my trust in this product.

Yesterday at 9:30AM, I applied SentryPro Squeeze-on Flea and Tick Control for Dogs. It was the 3rd time in 2 years that I have used this product. The first 2 times I used it my dog, Kelly did not have a reaction to it. This time she did.

I applied Sentry Plus in the early evening to my two small dogs. Upon reflection, I should have noticed they became agitated within an hour of application. By bedtime they were pacing, panting, barking, rubbing their ears on the floor. The poodle started to choke and cough around midnight and I finally realized that they were reacting to the Sentry and she might be experiencing a dangerous anaphylaxis reaction. The package warning mentions irritation at the site but no other reaction.

We administered the squeeze-on flea and tick to our 1 year old puppy, Jack. He was inconsolable with 10 minutes after application. He was whining, itching, and scratching. His back was literally twitching and his breathing was very irregular. We gave him benadryl and 2 baths but it didn't help at all. We ended up taking him to the emergency vet (because it was a Sunday) and spending $100 for a prescription strength med to help with the itching. This product needs to be taken off the shelf immediately!

This product is dangerous. I put the medication on my 20-lb cockapoo last night and he woke up in the middle of the night itching and acting very anxious. Flash forward several hours and he's been scratching under his skin (enough to make it very red), and he's not been able to sit still. He's constantly moving around, rubbing himself on the furniture and carpet, and looks to be miserable. I feel horrible for my little guy! This is the first time I've used Sentry and never had this issue with Advantage. I'll never buy this product again and put my poor dog through this misery!

After application of this product, I noticed my 20-lb dog twitching and acting a little crazy. He could not sit still at all for 48 hours and was not completely right for at least a week. I gave him Benadryl and washed him with Dawn and water 2 hours after application... but to my surprise it really did not help him at all. I felt terrible due to the fact that I bought product because of low cost. I can't believe this or these types of products are even sold. Now I am questioning all flea and tick monthly treatments. Please DO NOT EVER BUY this product.

DO NOT USE!! I put it on our tabby Kiki. She first got very aggressive as I even placed a drop on her. She is one of the most loving touching and desires to be touched and held cat. The reaction was a total 360 for her! I first thought maybe because I held her a bit tighter than normal, although she has never ever been aggressive in any way. She lives with us humans, as well as our large dog that are best friends. I placed the 'poison' on her and she immediately her back especially started spasming, as well as other parts of her body (back and shoulders were worse)! She meowed several times loud like she was in pain. When I first placed it on her, she took off and ran like crazy all over the place. She then tried everything she could to try to get to it to lick it off. Her pupils stayed wide even with light. She spasmed for hours and hours, even though I tried to get it off of her. Obviously it soaked into her skin quickly, or she may have gotten to it. She is very flexible and double jointed too. I did put it on as instructed!

After about 2 hours after applying the collar on our Jack Russell terrier, we noticed he could not stand up or lift his head! He was on his dog bed and was laying in a weird position and could not get up. He smelled like the flea collar. I immediately knew something was wrong from that flea collar and removed it. I called the 800 number on the box and they said this product has NO SIDE EFFECTS. What a lie!!!! This stuff is poison and no animal should have this on them. I read on this website to wash the dog with Dawn dishwashing liquid, luckily I have some. Even after towel drying him in the house which was nice and warm inside, his teeth were chattering and body shaking.

Sentry Pro XFT - I applied to my dog and the next day was picking, scratching, hiding under bed and would not eat. I read the post on here and washed my dog with Dawn Dish soap. She is still not feeling well and on top of that she still has fleas. PLEASE DO NOT used this on your animals. I will be contacting Pet Smart in Delavan WI and complaining this product should NOT be on shelves.

SENTRY FIPROGUARD plus IGR - I applied this product to my 6 month old dog on the recommendation of my local pet store. I liked the easy-open packaging and ease of application. Within a couple of hours, my black dog had a fist-size white patch at the back of her neck. When I checked to see what was going on, there was a horrible insecticide smell and a white powder coating had risen from the skin to cover her hair. I brushed it away, but the smell is still very strong. I will never use this product again!

I put SENTRY Purrscriptions Plus on my cat after giving him a flea bath. The next day, he's been mostly hiding under bed (didn't even sleep on bed all night with me, as usual), and he threw up!

I bought Sentry tick and flee medication for my dog at Petsmart, mainly for the price (much lower than K9 Advantix). I had been using the product for about 2 months on my 70 lbs chocolate lab with no issues. The evening after I applied the 3rd months dosage, my dog woke up in the middle of the night yelping. She had lost movement in her tail, was salivating, and panting like crazy. Her back legs also seemed to lose mobility. I immediately put her in the bath and washed her back where the medication had been put on. That seemed to help a little but she kept looking over her back like there was a bug biting her. The next morning we gave her Benadryl and a bath using Dawn soap.

A co-worker of mine rescued a dog who was living on the streets with his homeless human. Sentry flea & tick treatment was applied. At first the area got irritate and the dog scratched it causing a wound that scabbed up. I am fostering the dog and 2 days after I took him in (a few days after the application), a full blown oozing "hot spot" (the vet's words) emerged. It was extremely painful. Although there's no confirmation it was caused by the Sentry, it was in the location it was applied so the vet assumes that was the cause. The dog requires antibiotics, steroids, and 2x per day cleansing of the wound and topical medication.

Sentry Pro XFT - Don't buy this product. My cat is very sick right now. Salivating From the mouth and not eating. Very disoriented. Wash it off with Dawn soap and put vitamin E on the area.

We used Sentry Pro XFT on our Italian Greyhound mix, and about a week later, he couldn't walk on his back legs, somewhat like he was paralyzed from his waist down. We took him to the vet, and soon as we mentioned the Sentra Pro XFT we used for him, they knew right away what the cause was. Many dogs that our vet seen didn't make thru the terrible experience!! Our poor dog has lost so much weight since we applied it. He won't eat, unless hand fed people food. We have to carry him outside to do his duties and sometimes it's hard for.him to even stand to go potty!! Why is this product still on the shelves? It's killing our dogs!! Please, any pet owners that read this, DON'T USE SENTRY PRO XFT on your pets, worst product out there!!! I won't stop until it's off shelves!!!!

I used the Sentry brand Calming Spray for my cat. It has caused lethargy, muscle tremors & a confused state of mind. It caused him to go into an unresponsive stupor and he was immobile, even going limp in my arms for about an hour. Basically catatonic. He's slowly starting to come out of it but this completely terrified me! I DO NOT RECOMMEND THIS PRODUCT FOR YOUR FUR BABIES!

I wish I would have read the reviews before my son and I applied Sentry flea and tick to my Boxer and his Chihuahua last night about 7 p.m. I've always used Frontline and had no problems. I was told at Petco this was the same as Frontline but half the cost! WHAT A MISTAKE!!! My son woke up about 3 a.m. because his 14 year old, very slow moving, mellow, Chihuahua was running around like she was on speed! Twitching, gnawing at her feet, spinning in circles frantically, jumping up and down on the couch, panting and now having seizures.

I purchased Fiproguard at Petsmart on 08-June-14. I think I have used it before. I read the label carefully before purchasing because I remembered reading bad reviews on one of the flea products, couldn't remember which. Like I said, I think I have used it in the past. This morning, I noticed a bald spot where I had put the medication. I am concerned what I might find when I get home. I am appalled to see other consumers with the same complaint about the product when used on their cat. I will heading to PetSmart's website next to complain. Especially since I see several other complaints mention them specifically.

Yesterday morning I applied the Sentry Pro XFT to my 120 lb Rottweiler. He immediately was trying to itch and scratch where the product was applied. I thought he was just having a skin reaction so I used some wipes to wipe as much of the product off as I could. His reaction only escalated. He was madly trying to get to the spot where the product was applied. He could not sit still and was pacing the house. He had involuntary spasms and movements in his body and began hacking and making choking noises. It was like something was after him that only he could see. He used the bathroom in the house repeatedly which is very unlike my dog. I luckily have a friend that works for a vet so she told me to immediately wash him with Dawn and he was given Benadryl. This only relieved the itching slightly.

Sentry Pro XLT - I used this product on my large hound dog. Within 24 hours he began to have muscle tremors. A trip to the vet and $260 later, my dog was scrubbed down and given a mild muscle relaxer for the tremors. Thankfully he was a large dog 100 lbs. Vet said he would have had a full seizure had he been smaller. My vet said this stuff has killed pets as well as made many more sick. This product should NOT be sold.

I bought this for my 3 beagles and 3 cats, I put it on my dogs and was getting ready to use on cats and husband told me to look at reviews for the cats. I did and ran across this site. Done a lot of ready and decided after the 10th post to go and wash the dogs off (only had been about 2 hours since applied) DID not use it on the cats.......just hope I got it off the dogs before it got into their system...... Thanks for all the post on here and sorry for any furbabies that went through misery or worse....

My cat is probably 8 lbs and is 1 year 2 months old. He ventures indoors and outdoors, sleeps at the foot of the bed and wakes my wife & I by getting up in our faces and rubbing up on us with his motor going. He follows us on neighborhood walks. We feed him Blue Buffalo cat food products which is a great quality cat product. Anyway, our cat has not had any problems but we were worried about the mosquitoes, fleas and ticks that may be emerging as we enter Summer in Northern, MI. So, we were shopping at Tractor Supply and I noticed this product. It was more expensive than some of the additional products. I read the warnings and I felt that it should be ok if it is on the shelf and being sold as a pet treatment.

Used this product on my dog and he went nuts about an hour later trying to scratch his back. Up all night and miserable. I finally read some reviews and decided to bathe him with Medicated Itch Relief shampoo - twice. He is still itchy so I will have to give him a third bath. This product should be taken off the market.

Applied as instructed on 1 yr old cat. No signs of distress but 2 days later, a silver dollar size patch of hair was gone from area of application.... Cannot be good. Cannot find on box where manufactured so I have a feeling China?? Stay away from this product folks! I will let PetSmart know about this product.

Purchased sentry pro Xft a week ago. Put it on my Davy on Monday and since then, he has been itching and miserable. Called the 800 # on the box, spoke with a vet whom advised us to bathe him 3x with dawn dish liquid and them put vitamin E oil on the irritated skin area to sooth the skin. His itching has let up a little bit but still very restless. Going to return unused product as well as a visit to the vet. This is ridiculous. All those cheaper products claiming to be just like front line needs to be pulled off the shelves and banned! I can't imagine people who haven't written in here like we have. Very sad to see your fur baby suffer when you're trying to do them good.

On Sunday, May 25th, I decided to purchase this product from Petco. I wished I've done my research before putting this on my 21 lbs, Maltese/Shih Tzu. I applied 1 application as instructed on his back at 9 pm. Within 30 minutes, I noticed he was running around like something was on his back. He would run, bark and scratch. I immediately knew it was the Sentry. I looked at the back of the box to read if there was any indication of what the possible side effects. Then I called the 800 #. The rep said that some dogs might have a reaction. She told me to bathe him in Dawn. Nonetheless, after 2 baths and now 3 days later, he is still a bit off. I might have to take him to the vet. I realized cheap is not the way to go. You get what you pay for... DON'T BUY THIS PRODUCT!!!

I put Sentry pro xft flea and tick squeeze on my 2 dogs. Now they are shaking their heads and itching. They were not doing this before I applied the product 2 days ago. I hope they will be ok. I hope I do not have to take them to vet as I am sr. citizen on fixed income.

Sentry Fiproguard Plus IGR horrible! Bought this product at Petsmart because of the price instead of my usual frontline. I put this on my Chihuahua and forgot about it. Today while I was petting my dog I felt a lump and when I pulled the hair back it was a lump of dried blood. As I was bathing her, her hair was coming out in clumps at the site I have applied the Sentry product. She has an oozing sore which I will be getting checked out first thing in the morning. This stuff is utter garbage and I will be calling Petsmart and the manufacturer to complain! DO NOT buy this!!!!!!!

I went to PetSmart to buy my flea and tick treatment thinking anything they have there would be safe for pets. I'm sad to say I was wrong. We have two Shiba Inus and we put the Sentry Pro on them at 7 pm. All night our one just whined and screamed keeping us up all night. In the morning he wouldn't stop licking and scratching his back where the medicine was. Then we noticed our other Shiba wouldn't walk, she refused to move and when she did she would freak out like she's in pain.

Sentry Fiproguard Max - Immediately after I applied the flea and tick medication to my four year old lab she was trying to rub it off onto the couch. She wouldn't sit still for over an hour. The next day I noticed that her skin would twitch when I petted her sides and back. She has never been ticklish before. It's now a week and a half since the treatment and she is still very ticklish. So I decided to see if other dogs had the same reaction. I am horrified!!! I'm SO glad she had a mild reaction instead of the severe reactions I'm reading about. Since the product was sold at PetSmart I assumed it was safe. Not only am I horrified that it's killing dogs, but that some of these posts are a year old and it hasn't been pulled off the shelves! How many furry family members have to suffer before something is done?

The product is horrible, purchased it at Pet Smart. That junk needs to be taken off the shelf. Made the cat sick and the hair on her back has fell out.

We put the Sentry Pro XFT on both our 50-pound, very healthy 1 year old lab retrievers. 24 hours later, they are both in the animal hospital. Both dogs were itchy at first, panting, lethargic. We took them swimming. They seemed ok but kept slamming into the grass. The smaller one continued to do this then started attacking the air and her feet and tail. Called the 800 number on the package. They were not surprised and told me most dogs have these reactions but as long as she wasn't foaming at the mouth she would be fine but to wash her 3 times with dawn dish soap.

Our Beagle has had a terrible reaction to this. She has been shaking for days, is excessively thirsty, and scratching like she is infested with fleas. I wish I would have researched this product before putting on my dog. Purchased from PetSmart. Will be returning unused portion. DO NOT buy this product. It is poison.

Sentry Fiproguard - I bought this product because it was cheaper but still had the Fipronil and It was supposed to be like Frontline. NOT. Since using it on my 61 pound dog, he has done nothing but scratch and whine like he had fleas. I checked him every night, no fleas, ticks or the like. He continued to scratch and is now losing his hair. I wish I would have done my research before purchasing and saw this site. I would have spent the extra money to keep my dog happy. I will not use this product again. I did purchase the 3 month supply and am throwing out the 2 months and have bought another brand from my Vet. So instead of saving money it has cost me more than twice the amount. Do NOT use this product.

Sentry Pro XFT needs to be taken off market. Applied product onto back of my dog and 3 hours later, he was vomiting, shaking his head intermittently and drinking water excessively. Washed his back twice, then took him to an emergency vet. Vet gave him Benadryl injection and anti-nausea injection. We got home and he is restless, scratching his back and turning in circles over and over. I washed his back a third time but he is still miserable. I'm returning the product for a refund but am out $130 for vet bill. Will call company to lodge a complaint. I am very angry about this, and I will look into notifying our local TV news stations about airing a piece on this terrible product and how many horrible reactions it has caused!!!

Wow, I could not believe what I read on here after I researched when my Humphrey had the same symptoms that everyone else has. I can't believe that this product is still on the market.

I used the Sentry Pro for adult cats <5lbs. Immediately following application, my cat started freaking out like something was latched onto his neck. He's a pretty nervous cat to begin with, so I just initially wrote this off as a behavioral response to having the product on his fur. But then he started walking strangely, and chewing at his legs and trying to chew where the product was applied to his neck. I've never seen him chew his fur the way that he did today. I washed the product off as soon as I could, but it still had ~8 hours to soak into his skin. There are two raw spots that have been actively bleeding, one on his neck/back and one on his left leg. He's been panting, vomiting, and not eating as much as usual. I've been making sure he is drinking and eating, but will probably take him to the vet tomorrow morning if I feel that he is not making progress. My cat is otherwise very healthy. I've never seen him react to anything this way before.

We put this on our Pug and Boston Terrier early one morning before we went to work like we always do. When we came home that evening, both dogs were scratching as if they had fleas. The Boston was on his back scratching on the carpet; our Pug was hyper and just couldn't settle down. He was laying down in one spot for a moment then up and on to another spot. Each time he moved, he would lay down as if he wanted to relax but couldn't. The whole evening he was panting as if he was out chasing the squirrels. At this point, we didn't even think of the medicine being the issue since we got it from Pet Smart and if they were selling it, it couldn't be harmful. The evening didn't go well for him, he just couldn't rest.

It says it will kill fleas within an hour on our cats. We applied it to both our cat who got fleas, and within 12 hours we started to comb out fleas even on the spot where we applied the medication. It's been 36 hours and we are still combing out fleas, not only did it not kill the fleas but it doesn't even seem to repel. Absolute lies!

I purchased Sentry Pro XFT for both of my English bulldogs a few months ago. I gave them a dose right before the harsh New England winter, no problems. Now that the weather has turned, I gave it to them a week ago. In a matter of a few hours, my older dog Winston started freaking out like he was being bit by something. He began panting heavy, excessively salivating, running around the house yelping. I thought it could be a tail infection? The very next day my younger dog Opie started having the same symptoms. Too much of a coincidence... I knew it was the Sentry. I researched it online and found this website and my heart sank. I quickly washed my dogs in Dawn several times, Opie ended up in the ER vet because of hives, itching etc. both of the dogs kept us up all night for a few the last week.

I applied Sentry Pro around 6PM on my dog (a 100 lbs Labrador), and at around 7PM, he lost movement on both of his back legs. I asked him to stand up and he couldn't. I started to freak out of course. Then, he started to scratch and chew at his back, rolling on the floor to scratch back, and it was highly hyper/agitated. Wanting to know what was going on, I decided to read several reviews from Sentry Pro and found out how bad this product is. More than 200 reviews saying that dogs almost died, and owners had to give them baths using Dawn to take the stuff out. Sentry Pro is very oily, so that is why you have to wash your dog with Dawn.

I put Sentry Pro FXT flea and tick on my 5 year old Shih Tzu yesterday at 5:00 pm. By 9:00 he was acting very strange. He was panting, licking and licking his front paws. He kept barking at me. He was restless and pacing. He couldn't get comfortable. By 10:30 I thought it could be the tick medication so I gave him a bath. His symptoms did not subside. I took him to the vet today and the doctor thinks it was the Sentry. My dog paced and acted odd all day. He never slept all day. I gave him a Benadryl and he is finally sleeping, 24 hours after washing off the tick medication. I've always used Frontline without any issues, tried to save money with cheaper option, I learned my lesson!

I first researched this product in comparison to Frontline which I normally use. First mistake was going to Sentry to check it out; of course they will endorse it, saying it was equal to Frontline. Immediately, I noticed changes in my cat. He began losing weight, lost a circular area of fur on his head, poops in the house, and most times diarrhea, which he has never done. Gags and throws up his food, and when his stomach was empty, it is mucus. It has been over a month now, he is lethargic, sleeps all day, is no longer playful, won't go outside which he loved to do, is so skinny his spine shows, and drinks lots of water.

Last year in August, I bought Sentry Pro XFT at PetSmart for my 2 pugs because the ticks were especially bad. We had just applied it (1 tube for 2 pugs under 25 lbs. each). Three dabs as directed, not even one whole tube for 2 dogs. As soon as the "poison" was applied, both dogs acted like the devil was chasing them, looking over their shoulders, running around, trying to get under the bed, just plain crazy for these laid back dogs. I called the phone number on the package, was told to bathe them in Dawn which we did. Our smallest seemed to get a little better and we thought that with time they both would work this out of their systems. WRONG!!!

I gave my two cats the Flea and Tick Drops that Sentry sells in Wal-Mart. A few minutes later my cats were twitching and one was screaming at the top of its lungs, even locked his jaws down on my arm and wouldn't let go. I have never seen anything like this in my life. We rushed them to the emergency vet and they had to go on IV quickly. One was in a coma for two days and cost me $1700 in medical bills. They were foaming at the mouth. He was in so much pain and I couldn't do anything other than get Dawn and wash the product off of them. Day 3 and of going back and forth to the vet I think the smaller one has somewhat recovered but will have brain damage for life. You should see the video I have. THIS IS POISON TO YOUR ANIMALS. BE WARNED!

4 days ago I bought Sentry Pro Flea and Tick. Within 3 hours, she started scratching and licking at the air. She has had a horrible allergic reaction to it and for the last three days she hasn't eaten and she still hasn't stopped shaking. Don't buy this product. I am beside myself worried she may get worse.

I bought sentry flea ointment for my two dogs, one is 70lbs, one is 5lbs. After about 45min, the bigger dog started to not be able to walk with his back legs. I started freaking out because he's part of the family. I knew he didn't do anything because he was laying by me the whole time. So I called the phone # on the back of the box.

I had used Sentry Calming Spray for my cat because I was moving and thought it would be a good idea. I had used another type which was like a wipe in the past and it had worked well but this was a spray which I thought would be more convenient. I sprayed her carrier with it as it says on the directions and she was well with it. The trip - which was not a long car ride, about an hour was tolerated fine. Having moved before with her, I knew that I had to take steps to keep her calm during the time that the movers were bringing things in and out and then in my new apartment. I followed all the rules about keeping them in a small area with their food, litter and toys - she was ok.

I purchased Sentry Pro XFT and it nearly killed my dog. I was up all night while my dog had seizures and couldn't walk for 8 hours. I saw all the posts after it was too late. NEVER buy this product.

My Chihuahua has never had an issue with fleas or ticks and through his 6 his with reg baths. I have used drops on him maybe 3x a yr. This year we moved and apparently with the warm temps in fl and the fact that there were large dogs kept in the yard prior to our move he began scratching like crazy. I treated the yard and I purchased an oatmeal shampoo to ease his itching but did start to see a few fleas.

Kitty, my 4 year old cat appeared had a major seizure (lasting more than 5 hours) less than 24 hours after I applied this HORRIBLE product, which I've been using on my cat for months!! My vet never even heard of Sentry! He told me the active ingredient, Etofenprox is TOXIC. How could a company put a product on the market can potentially animals?! Apparently it's all about the "mighty dollar", instead of the safety of our pets. My cat had to stay at the vet overnight where she was given IV fluids, muscle relaxers & anti-seizure meds. I brought her home, and she's physically drained & has slept all day. It is my personal mission to get this product pulled from the shelves, & to have them reimburse me for the vet bill of over $300.00.

Having lost a cat using Advantage II last year because he ingested the product when grooming another cat, I must first say that I am very happy Sentry published directions for use in multiple cat households. HOWEVER: I applied Sentry's product to my cat as directed. Within 48 hours his fur fell out where the product was applied and his skin is irritated. WHY CAN'T SOMEONE MAKE A SAFE AND EFFECTIVE PRODUCT???

Applied it to my 5 yr old female healthy FLEA and Tick free Pit/Shepherd mix to prevent spring infestation due to unusually warm winter with no rain weight approx. 60 lbs. The first evening after application Annie began chewing at her hind quarters and whining constantly. I thought maybe she had a foxtail or other irritation never suspecting the flea medication or even fleas since she did not have any. I looked at her itchy area with a flashlight and magnifying glass to rule out possible bugs, foxtails and as the night progressed her symptoms worsened. She was having spasms in her stomach and hind leg muscles, twitching and couldn't sit still. She begged me to help her, she was MISERABLE and so I knew it had to be the medication.

I finished my first box of this product, a six month supply. Didn't really notice anything that unusual, but on my second purchase before I could finish the product my cat started to act crazy, running around like someone/thing was after him. I am also noticing patches of his fur missing. He constantly sit on my living room window sill and repeatedly just falls behind the couch, like he can't keep his balance. I am no longer using this product and I advise anyone reading this to also NOT use this product. Going to call my Vet. Very, very angry and concerned for my pet.

I bought Sentry Fiproguard Max for the first time after researching it online and finding it favorably reviewed by Consumer Reports. I put it on both of my dogs. One dog had a disturbing reaction. A few hours after application, he began to twitch and run around the house, sometimes scratching at the site of application. He could not be still. It was as if he were on speed, but also twitching. I gave Benedryl (as instructed online and by my vet), washed his back, and finally took him for a steroid injection. Nothing helped. It took about 48 hours for him to settle down.

My cat had been licking to the point that a patch of hair was coming off. After careful review I saw little mite looking bugs running around in his hair. Went to PETCO and bought this spray (Sentry PurrScriptions). Sprayed a light application and in about 15 minutes, he was acting funny and was foaming at the mouth. I put him in a cage and washed him down and went to store and bought kittens milk and a syringe after reading about this stuff. Seems like he is a little better now, but wife is monitoring him close as I write this.

We purchased the Sentry Natural Defense Flea and Tick Spray for Dogs and Puppies to avoid all the toxins believed to be in Frontline and similar products. This was a HUGE mistake. Several hours after spraying our 20-week-old Cocker Spaniel, he began vomiting, shaking, could not walk, and had tremors in his entire body. He was immediately bathed and taken to the emergency vet. The vet treated him with IV fluids and medication; however, we don't know if he will have permanent neurological damage and/or liver damage. We will know more on Monday after a blood test. We are devastated! He has been such an integral part of our family and we are furious that this product is still on the market and marketed as "natural and safe."

I applied this product on my adult dog, as well as my less than 1 year dogs. The oldest one started convulsioning after about an hour of applying it. She tried to stand up and kept falling in her face, she was dying! I dragged her to the shower as fast as I could while my son ran to get loads of milk and a syringe. While she was collapsed on the ground, I scrub the heck out of her whole body with warm water, then with human shampoo, then again for 15 minutes with LOTS of water while my son forced the half a bowl of milk down her throat. After I shut off the water and this poison was off her body and the milk downed, she went back to normal. All the sudden, my 5 months German Shepherd started having hiccups and panting really fast. I repeated the procedure but he is itching. This is a nasty dog killer product! Stay away from it! I did a research and LOTS of people have experienced the same and even fatal outcomes with this! BE CAREFUL!

I am livid with this company. I have two cats, both over 6 pounds, one happened to have longer fur than the other. I bought this product at Tractor Supply and had no idea of the danger of this product. I applied this ointment at 3:30 AM in the morning and when I got home, my female cat was anxiously twitching where I thought she was shivering. She also had refused her favorite treats - I called up my vet thinking that perhaps she had a cold or flu as I didn't know. I took her to the vet and he administered emergency treatment, where he injected her with medicine and gave her a bath and kept her overnight. My other cat didn't appear to be affected, but I do know that he has longer fur than she.

I purchased this flea medication at Pet Smart. Shame on Pet Smart for selling this poison. About 3 hours after application my dog started shaking uncontrollably. He also threw up several times and was panting. I was FREAKING OUT because I love my dog so much and thought that he was dying. I called the number listed on the package and was advised to wash the application spot with Dawn and repeat that 3 times. I also called my son in case we had to take him to the er for pets. My dog could not even stand/walk. It was the saddest thing ever to see him trying to reach me as I was trying to get the number for this evil company that keeps producing this product even though they have an extensive record of problems (even deaths) of dogs due to its use.
