Sentry Pet Products Reviews

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.

Save yourself money and a lot of stress and worry. I purchased Sentry Pro XFT for dogs 21-39 lbs for my 26 lbs Shi Tzu, Alfalfa. It was purchased from Pet Smart. Because they did not have my usual brand I got the Sentry. I was concerned because I already pulled 2 deer ticks off of Alfalfa and in two weeks he needs to get blood work done for lymes. I didn't want to take any chances on him getting any more ticks. I applied this product and like the other folks in this review, after about an hour Alfalfa was acting very strange. He was plopping down trying to scratch, moving non stop, wouldn't settle down, whimpering, crying and panting. He was flexing the skin on his back.

I bought Sentry flea medicine at Petsmart because it was on sale and I had no idea about the possible effects. My dog Isis began itching almost immediately and within 24 hrs looked like she'd contracted mange. Her ears were bloody and swollen from scratching them all night and she kept tossing her head like there was something in them. I rushed her to the vet where she had to be sedated and kept for 2 days to get it under control. They said at the vet that they've seen so many dogs come in after having Sentry applied to them - and that this product should not even be allowed on the market. A cheap 3-month supply of flea meds has cost me $600 in vet bills. I'd be happy to join a class action lawsuit on these guys. I'm a single mom with 2 kids right before Christmas - that wasn't where I wanted to spend my money. Please don't anyone use Sentry - it's not worth the sale.

Placed Sentry Pro XFT 21-39lbs on my puggle. Within hours she was crying in pain scratching and no playing. By the next morning she has sores on her sides and continued to scratch and cry. She was experiencing anxiety from the irritation. I contacted the vet who requested I bathe her in dawn to remove what was left of the residue on her fur and skin. I was also advised to give her Benadryl. My vet made a home visit and put her on pain pills and an antibiotic. I contacted company and was advised they'd refund my money and told me that any dog can have a reaction to a medicine just like a person can have reactions. Then the rep actually tried to sell me treatment for hot spots. Like I'd buy another product from this company. The big problem here is this is a widespread problem... Worst product ever! Shouldn't be on market at all. My dog has been sick for 4 days and still not over it. I've never been so mad in my life. This company needs to be stopped!

Two weeks ago, I put Sentry Max Flea & Tick on my cat. It was the last flea treatment on the shelf that didn't look completely full of it, so I didn't have a choice. My dog got Frontline. We used these products in conjunction with sprays for the carpets and fabrics, and both animals got a flea bath prior to application. After application, my cat developed painful red sores on the back of his neck. I waited 3 days to allow the product to absorb, then washed it off, and the sores went away. During those 3 days, I pulled a total of 35 fleas off him. Two weeks later, I pulled 9 fleas off my cat. I have been unable to find any on my dog. Sentry Max does not work. Do not waste your money.

I have a 10-year-old female Turkish Angora who is an outdoor/indoor cat. About two weeks ago, I used this Sentry Purrscriptions plus product first time. A few days after wearing the collar, I noticed she started to become sluggish and she was not walking around as much. Then she started to just lay at one spot for a long period of time. It never really hit me that it could be the collar. By the time I realized that, she was seriously sick, it was too late. I brought her to the emergency animal clinic last night and in the following morning, she passed away. The Vet didn't think it could have been from the collar and it was just a coincidence. After reading more reviews, I believe it was from the collar.

I put the liquid tube on my Chihuahua. 15 minutes later he was rolling all over the floor trying to get this stuff off. After 30 min. Sparky my Chihuahua was scratching like crazy and was whimpering. I go to website for this product and read some horrible reactions dogs were getting. I washed my Sparky twice within hour. It didn't help too much. Sparky was up all night shaking, scratching, shaking his ears. He couldn't lay still. The next day Sparky was still shaking, jumpy, he wouldn't eat, he would drink a little warm milk with Benadryl.. Two days later Sparky still wasn't himself. We took him to the vet. He got a shot and meds for his ears. Sparky is feeling better after 5 days.

Purchased Sentry Pro 40 - 60lbs and 60+ recently for our two dogs. Rottie, 8 years old and Shepard/Rottie 7 months. Normally, we use Front Line but because the weather has turned and the Sentry Pro was on sale, I thought we could get through the winter and save a few dollars. Once applied to our dogs, it was only a matter of an hour or so when the puppy began yipping and acting very nervous. She started shaking and nipping at herself.

Gave the dog a flea bath with Sentry Flea and Tick Shampoo around 6 pm. He started acting a little strange at 10 pm, put him to bed and he slept through the night. At 6 am this morning, we heard a lot of noise and came downstairs to the dog having a major seizure, vomiting, urinating and defecating. He has never had an issue before and this was the first time we have given him Sentry Flea and Tick Shampoo. Extremely scary and now I'm worried that he will have lasting issues.

I purchased 4 boxes of Sentry Fiproguard (3 tubes in each box) on Sept. 16, which was received a few days later and used immediately on my 12 cats (I am a foster home for a cat/kitten rescue). It has been two weeks now and we have more fleas than before as this stuff did not work at all. I contacted Petco and was offered a refund of less than half of what I paid, which was $86.00. I usually use Advantage or Frontline, which have always worked, but trying to save a few dollars I will now end up spending about $200.00. I have learned my lesson. I will only buy Advantage or Frontline as in the long run it will save me money. I would have been happy if they applied the $86.00 I had already spent toward the equal number of packages of Advantage or Frontline. I will NEVER buy anything from Petco again as they have proven themselves untrustworthy and won't stand behind what they sell.

I applied Sentry Flea & Tick Squeeze on my 9 year old dog due to a mild flea problem. The next day my dog had a major seizure and was rushed to the hospital. They had no idea what it was until I told them about the flea medication I put on. They said likely a severe reaction. My dog was in perfect health. I brought him to my vet first thing in the morning, had a complete blood workup, perfect results, of course I mentioned the flea product. And he said that Sentry is garbage and his suspicions is that it did neurological damage, but can’t prove it.

My cat rubbed my forehead with Sentry Purrscription Plus and now I have a rash. What to use to clear up the rash?

I have a small Cavalier Spaniel named Hunter who had an awful case of fleas a few weeks back. We bought this product after a "natural, oatmeal enriched" one couldn't cure him of the pesky bugs. It sure works. Fleas were immobilized and it looked like many of their legs melted off from the poison lather. My brother and I spent about three hours kneeling at the bath tub picking out all the little fleas. We found we had to take breaks every 20 minutes because the toxic smell from the shampoo we were inhaling made us nauseous. I hate to imagine how my dog felt, playing host to this toxic goop with his keen sense of smell. Hunter is not the smartest dog, but no joke, I wouldn't be shocked if he lost some of his few brain cells from breathing in this product.

Approximately 4 hours ago, I applied Sentry PurrScriptions Plus Cat & Kitten Squeeze-On Flea & Tick Control to 6 of my cats. At approximately 1408, I heard loud thumping and erratic noises coming from upstairs. I ran up to see my littlest girl tucked behind the closet door, convulsing rapidly and foaming at the mouth. I rushed her to the bathtub and washed her with a botanical soap as fast as I could, then gave her activated charcoal as soon as I could force her mouth open. She seems to be lucid now. Watching her very closely, as well as the other 5. Never, ever had a problem with Advantage II. Thought I would save some money with this product, and it almost killed one of my cats. This company needs to be shut down - anyone seeking to raise a class-action suit against Sentry, please contact me. Pretty sure we only need 6 people.

I bought this for my 2 indoor cats, aged 2 and 3 years old because I am tired of fleas on them every day. The older one goes outside once a day and brings them in so I treated her first.... not happy at all with this. She started by acting sleepy after 1/2 an hour and crawled up on my lap... then she peed all over me and I knew something was wrong. I immediately put her in the tub and started rinsing her with warm water, then bathed her with Dawn to remove as much of the product as I could. I should have read the reviews on this product first because this took me totally by surprise. DO NOT PUT THIS ON YOUR CAT. Take it to the trash and burn it... SERIOUSLY!!! I really hope I got ahead of the negative side effects from this or I will consider suing Sentry.

I wondered why my 1.5-yr-old German Shorthaired Pointer would act so strange when I gave him his flea/tick treatment. A few weeks ago, he started with a twitch in his one back leg. We thought it was very odd, but did not connect the dots. This morning I gave him his next monthly dose, and again he was very strange. He does not want to leave my side all day, literally glued to my side, very tired, sleeping all the time. Just for curiosity, I typed into Google "side effects from Sentry Pro" - OMG! In this day and age, how is this product still on the shelves. I just gave him a very good bath, and I'm hoping that we haven't poisoned our own dog. Something needs to be done.

I purchased Sentry Fiproguard MAX for my 55 lb. pit bull after trying a bunch of failed home remedies. It was a last resort I felt bad for him, he was scratching like crazy. After applying he wasn't himself at all!! He wasn't his normal playful self. After a few days his legs started twitching and he looked so scared. He was also trembling really bad... My son called me at work, when I got home he was laying down crying so bad, HE COULD NOT GET UP FROM A LYING DOWN POSITION!!!! I immediately took him to the 24 hour animal hospital. They checked him and shaved the hair from around his neck and IT WAS RAW!!! My poor baby!!! I feel so bad... I was trying to help him and he COULD HAVE DIED from this stuff!!! $505.00 later he is slowly getting back to normal. He is on a bunch of medication. I am thankful that I took him right away!! PLEASE DO NOT BUY THIS STUFF!!!! IT'S WAY TOO DANGEROUS!!! I called the number on the box and they could care less!!! I wish there was something that could be done about this so it no one ever has to go through this!!

I applied Sentry Flea and Tick for Cats and Kittens to my 5-month-old kitten 6 days ago. Last night he suffered a seizure lasting for about 15 seconds - he also urinated all over himself. This morning, he had another seizure so I rushed him to the vet hospital where he had two more seizures. The vet determined it was the flea medicine and he has to be there for 5 days. Do not buy this because it is cheap - like I did. The vet bill is going to be way more than Frontline or Advantage would have been and is much safer. My kitten also still had fleas 3 days after application.

We purchased Sentry PurrScriptions plus for adult cats at Petsmart as we recently had a flea problem and had five indoor cats. We also aren't in the best financial situation, so the $15 price tag was a lot more affordable than Frontline, which we had always used without any problems. In the end, we are left with an atrocious vet bill and we have to bury one of our babies. They seemed fine when it was applied, but our black ragamuffin seemed to be lethargic the next day, so we took her to the vet and she did everything she could but the cat had to be put down the following morning (9/8/13) because of becoming anemic and falling into a coma. The vet doesn't know if the anemia was related to the fleas, but the flea medication definitely poisoned her.

I have not had any fleas and I prefer it to the harsh chemicals we put on them. Also my cats are indoor only and never have been outside except to go to my vet in Alden, NY - but I have no complaints. I'd rather they offered bigger packages for people with multiple cats.

I have 2 small dogs that had gotten fleas. I went to Pet Supplies Plus and bought the Sentry Pro Toy and Small Breed formula. I gave my smaller dog a half dose and my bigger dog (Dexter) a full dose. Dexter has not eaten more than a couple bites of food since. It has been 2 days! Dexter now has uncontrollable, bloody diarrhea and is lethargic. He has an appointment with the vet first thing Monday morning... Until then I can just hope that he gets better... If not, I will be taking him to the hospital.

My husband and I noticed our dog had fleas. We decided to not only treat our dog but, to prophylactically treat our cats. My husband purchased the Sentry PurrScriptions Plus flea med for cats. Approximately 1 hr after treating my cats... one threw up and the other threw up and was foaming at the mouth. We then wiped their backs hoping to get rid of any remaining medicine. 24 hrs later, both cats were somnolent and just "not themselves." I then noticed my small cat had a significant twitch in her back legs. I then call the vet and took my cat in for a visit. According to my vet, the ingredient in that medicine is TOXIC to cats!!!! Despite being marketed for cats, it's toxic. I now have to give my cat medicine and she still is twitching. I cannot believe that not only can the company sell this medicine for cats but that a pet store can sell stuff that is known to be toxic to animals. I'm angry and I am not finished letting people know!

Do not buy Sentry Pro XFT Flea/Tick products. We purchased the flea treatment at PetSmart last night and applied it to our 9-month-old Golden Retriever. We left the house for a few hours and when we returned our poor puppy was a mess. He was crying, scratching like crazy, panting, and pacing back and forth. It was so sad. He wouldn't stop so we Googled info about Sentry Pro and were Horrified! This stuff is nothing but poison! There are hundreds of complaints and lawsuits. We wished that we looked up this crap of a product before applying it to our puppy. It also isn't FDA approved... Well its been over 24 hours and 6 showers with dish soap, vitamin E, ice packs and zero sleep for all of us. He finally is getting a little bit better. Please don't ever purchase this product and tell your friends and family how horrible it is. No animal should ever suffer like our poor Charlie has.

We used the Sentry Flea and Tick Squeeze On for Cats 24 hours ago. After 8 hours coming home from the office, I found my cat having ticks and unable to balance or walk. She was soaked all down the front. She was twitching horrifically. She tried to follow me down my stairs, ended up falling down the stairs and immediately having a seizure (never has happened prior). I was mortified, and immediately called the vet, was told to wash her in Dawn dish washing detergent to cut through the oil and then give her Benadryl. She was unable to eat, but I put her in front of her water bowl where she drank for literally 5 min. straight. Started looking up issues on the computer and unfortunately like the majority online, found horrific stories of liver failure, kidney failure, permanent central nervous system problems... death. I'm terrified she will be disabled or worse, die. I cannot believe this has been happening to pets for over 10 years and this product is still available? WHY? If this was happening to humans, it would be taken off the shelves IMMEDIATELY. Our entire family is devastated. My poor once happy active cat is now like a 100-year-old person stuck in a wheelchair. Please do something.

I just used Sentry flea medicine on my 80 pound dog about an hour ago. Probably like 10 minutes after using it she started acting crazy. Running laps in the living room, pacing back and forth heavy panting and just could not seem to get comfortable laying down. So I decided to Google this product and was completely HORRIFIED at what I found. I feel so terrible for putting my dog thru this for just an hour!! My fiancé and I gave her a bath immediately. All in all she only had it on for about an hour, and she already seems to be doing so much better now. I don't understand how a company can sell a product that causes so much damage to a dog so quickly. I will also be contacting PetSmart because one of their employees recommended this product to me. It needs to be taken off the shelves at ALL pet stores. DO NOT USE THIS PRODUCT. It's basically death in a tube.

It was time to treat our year and a half old Shepherd/lab Zoey. She began biting at her legs and scratching constantly after about an hour. We thought visitors had brought fleas into our home after they had complained about having them at their house. I applied a very small amount to our year-old cat also to protect him as well. Zoey kept us up all night scratching and biting at her legs and back. Tiger (our cat) began having leg twitches and shaking them. He is trembling, his eyes are dilated, and he is shivering like he is in pain.

We are under tight budgetary constraints, so we bought Sentry flea repellent for my son's cat. My son applied the product between the shoulder blades, as instructed, and within a minute noted that our lovely orange monster was foaming at the mouth. We tried wiping the product off, but he started to foam up again... In the meantime, my son had googled and found this site. We used shampoo and cleaned the product off his shoulder blades and kept an eye on him, and he returned, slowly, to his own special breed of normalcy.

We put the Sentry Purrscription spray, within two minutes both cats were convulsing and foaming at the mouth. My husband immediately washed them both in the tub and I found this site. We are horrified and praying our little guys are going to be okay. The only things not hurt were the fleas. Why is this product on the market? Good vibes to all those affected by this awful product.

Sentry Pro XFT - I applied this medication to my puggle around 8:30 at night. At first she seemed fine. Then about an hour later she started itching and threw up. Before long she was beside herself. Couldn't seem to get comfortable... kept getting up, laying down, whining, repositioning, going in and out of the room. She also kept shaking like she was wet. I decided to google "my dog is acting strange after flea medicine" and Sentry Pro and all the reviews came up. I flipped out! At this point it was 2am but I threw her in the bathtub and scrubbed it off. This settled her down a bit for the rest of the evening, but tonight (almost 24 hours later) she is still a hot mess. Her ears are so red and inflamed. She is still shaking her head and body constantly. She is scratching and biting herself all over. Right now she is whining and seems like she is about to crawl out of her skin. :( My poor baby... I feel horrible that I did this to her!

I purchased Sentry Pro XFT and immediately, my 60 lb. pit bull ran around like crazy. I thought he just had to get use to it, but it's been 3 days now and his skin is still twitching!!! I also washed him twice with Dawn dish detergent and no relief. I'm taking him to the vet tomorrow. Hopefully they can help! This stuff is poison! Do not buy!!

I bought Sentry Fiproguard Max for my mother's two cats. Worst mistake I could have made. A few hours after application, the cats' eyes were so dilated, they looked like an owl's eyes. The cats were still scratching (like they still had fleas). The box claims the medication starts to kill fleas and ticks within an hour (NOT TRUE). Both cats have had explosive diarrhea since applying the medication. Both cats have stopped eating and drinking water after application. It has been 24 hours and they both still have diarrhea. We took baby wipes and washed the area of application and will probably have to take the cats to the vet in the morning if they are not any better. When cleaning the site of application, we noticed LIVE fleas. This is the worst product on the market and needs to be removed IMMEDIATELY. I do not recommend this product for ANYONE to use on their cats or dogs.

I have an 11-12 year old Torbie by the name of Pouncer who had been exposed to fleas. I went to PetSmart to get her some topical flea treatment and got her something called Sentry Fiproguard, which claims to contain the same active ingredient as a Frontline product. I gave her a bath with some cat shampoo that contains no parabins, waited for her to dry, and put the treatment on her as I normally do.

I bought Sentry Fiproguard at Petsmart because it was cheap and on sale. I used it on my cat on 7/23/2013. Over the last couple of weeks I have noticed my cat's lower lip swelling then his chin now his ears and eyes are swollen. I am taking him to the vet tomorrow. Please go to Facebook and look for lawsuit against Sentry. There needs to be a certain amount of complaints to file a class action lawsuit. This is just an evil act for a company to sell crap that is killing our fur children.

Within 30-45 minutes of applying to our 4 year old cat, she had a seizure. She was rushed to the vet. Spent 3 days at vet. Did not eat for 4 days. Over 1 week later, she is still having neurological/muscular problems but is eating and behaving more like herself. Do not use this product. It can be extremely dangerous.

Put on flea medicine on my cat, thought the package was for her because it had a cat on it. I have bad eye sight and the other package had nothing on it so I thought that was for the dog. Gave her the wrong medicine. She went into tremoring/twitching. Took her to the vet where she was given emergency care and that cost me $1150.00 for poAVor packaging. They should package the products saying dog and cat cents, it is poison and giving the wrong one to a beloved pet can kill. It should be packaged better. This happened on 7/27/2013 to 7/28/2013 at Coral Springs Animal Hospital 2160 University Drive Coral Springs, Fla 33071 (954)753-1800.

I used the Sentry Pro on my female St. Bernard and within 30 minutes she had become very agitated, heavy breathing, can't lay still, chewing at herself and crying. I gave her a bath with Dawn dish liquid but didn't seem to help. It has been 12 hours and my poor baby is still having these issues. This product needs to be taken off the market and for these stores selling the product knowing it is poison, they are just as guilty. I am so upset over this, I can't sleep either. I guess I will be up all night too trying to comfort my baby. This company should be sued. I bet they don't use it on their own pets.

Used Sentry All Natural Defense for cats and kittens - she started becoming lethargic, wouldn't eat, became anemic, rushed to vet. They took blood, her kidney levels were toxic. Spent over 2000 trying to save her. We lost her. I called Sentry number after Googling hundreds and hundreds of similar complaints against this product… complained to the department on phone. They then transferred me to the "medical review" department where the woman hung up on me.

Sentry Fiproguard - This is a prime example of getting what you pay for... Will never buy this product again trying to save a little money. My poor dogs are miserable. This crap is just that - crap... My dogs have never had fleas till we bought this product and now they're loaded with fleas. Don't waste your money and put your poor animals through this!!!

We started using Sentry Natural Defense on our 3 1/2 year old mid-size dog 4 months ago because she had been very listless and not eating well the first 2 days after her prescription drug treatment each month before Sentry. We tried several different brands, without success, since we got her as a puppy. Last year was our worst flea year ever and we started trying other natural products along with the monthly treatment to help her.

My family and I are on a budget like most people and trying to save a little money. We decided we would try Sentry instead of Frontline. That was the biggest mistake of my life. It made my dogs itch 10 times more. At first it was just one of them itching more and I thought, "Well, he's allergic to it or it's just dry skin." But now they're both miserable and making me a nervous wreck. DO NOT WASTE YOUR MONEY OR TIME ON THIS.

Miserable dog was jumpy and nervous, licking and scratching himself with dry heaves after I innocently applied the pesticide Sentry offers to "help" Cocker Spaniel avoid flea and tick problem. I tortured my dog unknowingly. How can this stuff be available when it is so harmful to pets? Beware!

I bought Sentry's Fiproguard Max for Cats in April. It was expensive at about $55.00. I used it on my two (2) cats for two (2) months, and it NEVER worked. My cats ended up with a very bad case of fleas, and I had a flea infestation that I am still trying to fight in my house. I have never had this issue with other brands. It was just that I was in PetSmart and saw this product. I still have two (2) vials which I have not used and won't. This product should be taken off the market as we, the consumers, are being taken for a ride! And it's a costly one, at that.

I used the 60-lb. dosage of Sentry Pro XFT on my 80-lb. Boxer/Pit mix, a BIG MISTAKE! He is scratching, fighting, shaking and can't get comfortable. After reading ALL the reviews online, I realized this is a NORMAL Side effect and could be FATAL?!! DO NOT USE THIS PRODUCT!!! I am absolutely amazed this is legal. It is definitely not moral to sell! This company's CEO should be in jail!

Frank the cat started to foam at the mouth and became very inactive after spraying him today! Let's hope he snaps out of it! I will let you know.

Sentry Fiproguard - I used this product on my small dog. He has never had a flea problem with other products, but this product does not seem to work at all. In fact, I cannot tell a difference between NO treatment and the treatment effects. I ensured he was bathed and absolutely flea-free prior to application. However, within two days of treatment, he has fleas! Do they ATTRACT fleas? I am sorry I attempted to save a few dollars. Never again.

I used the SentryPro topical flea and tick treatment on my small breed dogs. One of my Shih Tzus had a toxic reaction. She stopped eating and drinking and was unable to walk or sit. I took her to the vet and her temperature had dropped to 99.8 deg. By this time, she wasn't even able to hold her head up. They gave her warm fluid treatments to combat the temperature drop and dehydration and IV meds to reduce the neurological effects she was having. We're waiting on the results of her blood work to see what damage has been done to her organs. I have to give her daily subcutaneous fluid treatments and to syringe feed her. At least, she's drinking and urinating now, but she's still unable to hold herself up. So far, the others haven't had a reaction, but I've washed it off of all of them anyway.

I spent right at $30 for flea and tick collars, but none of them work. I have had the collars on the animals for two weeks now, and they are not working at all. I would like a refund.

I am horrified at the reviews I have read about this product. I was advised to purchase it since I am on a limited income and I used a tube on my cat (1 year old) and one on my older cat (9 years old). I applied the medicine on Friday night and put them in the large bathroom so I could treat the rest of the house. They both got a little sick, but when I let them out, they seem fine. They are running around and playing and eating as normal and I can't locate a single flea. So for my money, I would say the product worked. My older cat is still scratching, but I can't find any fleas, so the vet said she may have some residual reaction from the bites and they may just be itching. Today is Monday and my son said she is not scratching as much as Saturday and Sunday, so she appears fine. I will be watching her as I cannot discount the previous reviews about what happened to the other pets that were treated with this product.

I have three dogs and two cats. I put Sentry flea medication on all five pets using the correct formula for each of the pets. My three year old Shitz Zhu was agitated all night and kept me awake because she could not stay in one place for more than ten seconds. One of my cats developed a sore where the medication was put on him. My dog recovered the next day but it took a full 24 hours. My cat still has the sore. It has been three days since I used the product. I threw out the packing so I can't say exactly which Sentry product it was, but it was for fleas and ticks.

I am furious with Sentry Purrscriptions. My husband and I decided to get it to save some money and used it on our indoor cat. Almost immediately after putting it on her, she began to shake really bad and acted as if it hurt for us to touch her. She could barely walk and she also started foaming at the mouth. I did some research and found that many cats have died because of this. I washed her immediately. She is eating a little, but she is still hot to the touch. If she dies, I will be suing the company and the store that we got the product from (PetCo).

I'm so mad that PetSmart is selling such bad and dangerous products for our dogs, especially for owners like me who do not research products that I believe are safe because PetSmart has them on their shelves. I gave my dog a flea and tick treatment. I never had any problem with Frontline. Soon after the application, my dog started to shake, itch all over his body and had difficulty breathing. It was scary. Of course, that happens during the evening when my vet is no longer reachable.

I can't believe that a product that can kill your beloved pet through its regular use is sold so readily, especially by trusted stores such as PetSmart! These people need to be sued. This past Saturday evening, I applied Sergeant's Sentry Purrscriptions Flea & Tick medicine to my 12-yr-old cat as instructed. A few hours later, I noticed that he did not come down for dinner. I found him in a crouching position, breathing very heavily and with widely dilated pupils. I used a wet washcloth to remove the medicine from his neck area and tried to give him water, which he would not take. When I was doing this, he was not reacting or responding to me calling his name and trying to catch his attention. His pupils were so wide and he looked like he was in shock.

I purchased Sentry PurrScriptions Plus for cats 5 lbs. and over and after two days of putting it on my two cats, one started losing fur really bad and is now bald on the spot and I know it is bothering him. He keeps trying to lick it. I will never buy this product again; it is not safe at all.

On Saturday, 05/18/2013, we purchased the above product (23-44 lbs) for our 9-year-old beagle. Within an hour, he suffered severe complications. He had a seizure (never had one before) and was crying. My husband called the vet. They told him to give him a bath as soon as possible; that gave no relief. We rushed him to the vet. Now, $158.74 later, the vet tells us this was a severe reaction to this product. He may have permanent neurological damage. They shaved the area where the product was placed. Now, our poor Snoopy has an antibiotic cream for the shaved area, an oral antibiotic, and steroids. Please be aware of these possible complications. They need to take this off the market!

I purchased it twice. Every time I use it, my cat loses her hair where I apply it! It takes about a month for it to grow back, and then I start all over again with the same results. I will not purchase it again!

I bought Sentry as a good alternative to chemical-based flea and tick control for 2-year-old male cat. I figured if these big chain stores sold this product, they would have done their research before carrying a death sentence in a box! I applied the solution as directed onto my cat; immediately he foamed at the mouth. He eventually stopped as my concern was growing. However he began to walk weird, lifting his paws almost like a clown on stilts. The solution was starting to spread further down his fur making it easier for him to lick at. After witnessing all this (about a one-hour period), I got on Google and researched the product and reviews. One review after another... my cat died using this product. My heart sank!

I washed my dogs with the flea shampoo and then put Sentry on my pets. I have gone through this round three times and my dogs still have fleas. What a waste of money! Sentry does not work! How many times do I need to bathe my dogs and put the medication on them for it to work? Sentry sucks!

I would not recommend this product to my worst enemy. I used flea and tick product on my 10-year-old male cat and 2-yearold male Siamese cat this weekend. Within hours they were not able to walk. They were shaking constantly, hallucinating, and my younger cat started having seizures and foaming at the mouth. This product needs to be taken off the shelf. If you do use this product by mistake, please quickly wash it off your pet with a mild dish soap and water. It seemed to have saved my babies. I continuously washed the area until it was gone. It took a good 72 hrs to where they were able to eat and walk again. It was an extremely scary situation. Once again, do not use this product. It's deadly.

Not only does it kills fleas and ticks, but also dogs. My dog is constantly scratching itself, and he did not sleep the whole night. He keeps crying and running around.

I put it on my indoor cat Bubbles just to be safe. Her hair started falling off where it was applied and she was bleeding because it burned her skin. Do not use this product! If you use this, your pet will suffer, you will have huge pet bills, and you could end up losing your pet. This should not be allowed to be sold.

This product should not be on the market. It made all three of my pets sick. Sentry made all three of my cats sick and sent one to the vet (where she still is currently). I applied it to all three of them on Saturday night. The fleas where we live have apparently developed an immunity to Frontline, and it no longer kills them all completely. We decided to try Sentry than the more expensive Frontline for the 5th month in a row. I noticed one of the male cats acting odd when I went to bed on Saturday night, but thought that he was just irritated about having the Sentry on his back.

Sentry Purrscriptions Plus made my cat's skin turn bright red, get irritated and hurt my cat. He keeps scratching at it and his fur comes out in clumps. I'm extremely dissatisfied and pretty worried about him.

My dog had a little white bug infestation and the product I was sold on by the store employees was Sentry Fiproguard Max. My cat had the bugs on him too, so I got the proper treatments for both. I applied the product to both and everything should be fine. I quarantined my cat for the 24+ hours in my room. On account, I have two cats and the other I was planning to treat when she came in. Luckily, I put it off. After a couple of days, my treated male cat seemed to have a stomach condition, has foam on the carpet, a little feces around the cat dish. He totally quit eating. A couple days more and he died suddenly.

This product does not work. I applied it to my dog two weeks ago (and made sure to rub it in to his skin and paws). He is still covered in ticks and he is itching more than normal. Normally if you apply Frontline, the ticks at least fall off and you find them on the floor. These ticks are still grasped on to him. I feel like I simply bought the dog an expensive deodorant. Aside from that, I am a little startled to find that the product was available for me to purchase at all. The customer complaints of pets dying, getting sick and this product not working go back four years and still this product remains on store shelves. There are not even any good comments to weigh out the bad, so again I have to wonder why was this product still on the shelves available for me to buy in October of 2012 anyway.

Please, if any of you have animals, this is a warning. Do not use Sentry products on your pets. My wife and I are on a limited income, and we tried to save money and talked with the people at our local pet store to see if there was a less expensive Top-Spot application than Frontline. The employee told us that Sentry products were safe, so we bought the Sentry Purrscription Plus (green box) for our cats. One cat became aggravated and nasty - wouldn't even let us pick her up to see what was wrong and the other developed UTI, became anemic almost immediately (you could tell by the white gums) and he would bite off pieces of his fur. By the time we got him to the vet, it was too late. They tried to reverse what the Top Spot application had done, but he died the next day. I feel horrible about this as I was the one that made the decision to go less expensive. Please do use these Sentry aka Sergeant's products on your pets. There are many sites online that have horror stories like mine regarding their pets.

I purchased and applied Sentry Fiproguard on my cat as directed. Within 24 hours, I noticed that she has lost her hair at point of application. I am in horror reading the stories of the other pet owners. Please do everything possible to get this product off the market.

The minute Sentry Pro XFT was put on my Cocker Spaniel-Bichon mix, she started going crazy and cried all night due to the pain. We washed her 3 times to no avail and had to take her to the vet. But the product continued to irritate her and cause extreme itching. Approximately one week later, she broke skin on the area and ended up with a huge open wound on her neck/back area that is approximately 2 in x 4 in. The wound got infected, and we had to take her to the vet again yesterday. As you can imagine, my dog is in extreme pain and has been suffering too long because of this dangerous product. I submitted a post regarding this on Pet Health Central's Facebook page (sponsored by Sergeant's), and they immediately deleted it. It appears from the numerous complaints that Sergeant's is fully aware of all of these issues and risks, yet they continue to market the product as safe and effective because they value profits more than the well-being of our pets.

I have two outdoor cats that need flea plus tick protection. I thought I did my homework and checked the active ingredient in Frontline with the new Sentry Fiproguard Max, since it was about half the price. I purchased it at Pet Supplies Plus for $74.98 per 6-pack. My cat has been treated with it for almost two weeks and still has live fleas daily. What a complete waste of money! I can't treat again for another two weeks. I'm calling for a refund. It's ridiculous. We went through all this years ago with Hartz and then Bio Spot. What a shame our pets have to suffer like this.

Last Thursday, we went out to get some flea medication for my two cats. He is on Social Security Disability and my job is ending in a few weeks. So, we asked an employee at PetSmart what she would recommend. She recommended the Sentry PurrScrtiption Plus saying that it worked as well as Frontline, which is at $62.00 a box. Sentry was $19.00 a box. I put the medication on the two of them that evening. The girl cat was dead that next morning by 7:30 AM and the other cat started getting sick a day later. By the time we got him to the vet, it was too late. They tried an antibiotic to reverse what the Sentry was doing to his skin, but it was too late. He died the next day in my husband’s arms. Please, please, do not use this product on any of your animals.

I own 13 cats and I found two fleas on one of the cats, but I ordered flea meds for all 13 to make sure that no one else got them. I treated them three weeks ago and I just noticed that there were red spots behind the toilet seat which is a telltale sign of flea eggs. I did a combing of all thirteen cats and they all but one has fleas; they are infested! The one who doesn't have them got the last tube of Frontline that we had from last time.

Do not use this product. After using this product on my cat, she began foaming at the mouth! I quickly washed off the formula and her symptoms improved. This product is harmful to animals and a waste of money.

Like many others, I saw this product was compared to the name brand flea/tick products. I went from three dogs and a cat with no fleas to a house and animals infested. My Wheaten chewed a chunk of hair off. I am waiting to hear back from my vet to see if I can retreat with Frontline or Advantage, products that actually work. I had to cancel grooming appointments because I was too ashamed to bring my dogs in. I will also have to bomb the house. Awful product.

I had purchased this product from Tractor Supply. I had put it on my poor cat and one day later, she started acting funny. Then by day 3, she was not moving much. I took her to the vet and she died. The vet told me that it was this flea medicine I put on her. I felt so bad as a pet owner, I thought I was doing a good thing but I did not. The end result for my cat was death. I adopted this cat from the SPCA. She was a healthy cat. I feel so bad. I wish I could have done research first, but I definitely won't put any more flea medication on any animals. My cat was part of my family and when I had to say goodbye was like ripping my heart out. So please don't use this product. I ended up with a dead cat, a vet bill and a cremation bill. RIP Bubbles. Sorry, I was stupid using this product. Baby girl loves you so much, but I am so sorry.

Sentry Fiproguard for cats - Following all directions, I applied the Sentry product to 3 cats. I was hardly done with the third cat when the first cat started foaming at the mouth. Foam poured onto the carpet! All 3 cats foamed at the mouth in the same order as I applied the medication. In a panic, I rushed each in turn to the kitchen sink and used paper towels to soak up as much of the insecticide from their fur as possible. I then poured water over the back and used more towels to dry them. No further symptoms were observed.

We have been having a major flea problem and financial problems. We bought Sentry Purrscriptions flea killer and I am seriously wondering if my cat died because of it. My 19 year old oriental short-hair died within a week of putting it on her. She was the one with the worst flea problems. She ended up having seizures. Eventually she was lethargic and couldn't eat or drink unless I fed her with a syringe. She is gone and now I wonder if I killed her. My other cat, my Maine Coon George, is sick now too. I can't take him to the doctor until we get paid on Friday. I bathed him a couple days ago, but my husband has been spraying it around to get rid of fleas on the couch, etc. If my other cat dies, I will die inside myself.

I have used Sentry Pro Toy Flea and Tick spray every day for a week and had the same result as if I had sprayed water on my dog. I paid good money for this product and it was money thrown away. I can't believe your company actually sells this product! It is a ripoff. After I finish this e-mail, I am going to Facebook and Twitter and let as many people as possible know what a scam and ripoff your company is. I can't believe that you are allowed to sell this product in the United States. It should be against the law!

I've used Frontline for years on my pets and I decided to go more natural. I purchased Sentry Natural Defense. The odor was so strong it gave me a headache, nausea and sinus problems within the 1st hour. If I were feeling like this, God knows how my dogs were feeling, considering their noses are a lot more sensitive. I left it on overnight. The next day, one of my dogs was very sensitive to my touch on the back, so I washed both of them thoroughly. I could still smell it, so I didn't apply anything else on them. Then my other dog started scratching (both of them really but one much more than the other) and hasn't stopped since then (22 days ago). I've bathed him quite a bit to get that smell off but to no avail.

I purchased your product to save a little money. I have in the past been a committed Frontline user. Times are tough financially so I unfortunately decided to save some money and go with your product (Sentry). I applied the proper dosage to all my Chihuahuas, ranging from 3 1/2lbs to 11lbs. Within a day, Jax, my 11-lb boy started chewing himself until he had raw and bleeding spots all over his back side. By the next day, I noticed his lips were raw and swollen, and in the night, he had scratched his right eye until it was raw and swollen. I started giving him Benadryl and things, he slowly stopped the all consuming scratching and biting. I took him to the pet supply store where I purchased your product and upon looking at him and me explaining what was happening, they immediately exchanged the unused portion for what I should have originally bought, which was Frontline.

I recently had two of my family pet cats die from Sergeants Sentry Purrscriptions Plus flea treatment for cats. They were both poisoned by the product, in which I followed all of the directions. The product killed our family pets and I reported it to Tractor Supply where I purchased the products and to Sergeants. Both told me that if I had the original purchase receipt, they would consider reimbursing me for the product. Both were not interested in the loss of the animals. There is no recourse for the consumer who is basically their test facility and R&D department for these pet products. They sell the product, which is basically not regulated because it is for animals and not humans (the FDA told me they were not interested either) and to contact the EPA because it is a pesticide.

My cat is dying after using your treatment. I used the Sentry flea meds on my cat and a couple of days afterwards, her ears were all raw, she started foaming at the mouth and throwing up, and having diarrhea. I am a student on a fixed income and trusted your company. Now, my cat could possibly die and I cannot afford to get her treated. I will be joining the class action lawsuit against your company for my cat’s illness or death.

I am a senior citizen on a limited budget. However, my dogs needed something good and strong, for this is a bad flea year. So I sacrificed and bought your product (Fiproguard Max). I bought two boxes from Petco. I have two dogs. But when I opened the box, one tube was bone dry and the other had only two drops in it. I had to use two more vials and I am not sure if there is any left in them. Could you please help me out?

I have been using the Fiproguard for Cats and Dogs, going on three months! The cats are covered in fleas; the dog, not so bad but has fleas also! I have never had a flea issue with seven cats and two dogs. They are treated the first of every month!

I put Sentry FiproGuard Max for Cats on 4 adult cats and all four lost their fur and have burn marks on their skin where I applied.

Sentry Home and Carpet Spray/Shampoo - I went out of town for Easter and had to put my dog outside for 4 days. When I came home and brought him in, he was covered in fleas, and my house became contaminated. I went to the store and bought Sentry Shampoo and a competitor's carpet and upholstery spray. I used the spray, and it did wonders. I could see the fleas instantly dying on the carpet and entryway as I sprayed. I then bathed my dog with the Sentry shampoo. Not one flea died on him. I went back to the store and bought another bottle of carpet spray, but this time, bought the Sentry one because it was $1 cheaper and I figured the other one worked so well, might as well save a penny. Wrong! Like the shampoo, it didn't do a ** thing.

I used Sentry Flea & Tick Squeeze-on on my dog on 3/18/12. I watched him continue to get ate up by fleas until I could not stand it anymore and contacted this number, 1-800-244-7387. I was told that it would be okay to apply a second dose to my dog, which I did on 4-2-12. Today's the 6th and he still has live fleas on him. This product does not work and you should be ashamed to sell it to the public!

I applied Fiproguard to my dog who reacted bad, hives, itching, vomiting, no eating. It was treated with steroids and fluids by my vet. Sentry told me on the phone no other reported cases and to wash her with Dawn dish soap and vitamin E. I looked into ingredients which is over 90% Diethylene Glycol Monoethyl Ether and turns out according to EPA website when it was registered, no further studies were done because of the unlikely humans would come in contact and it was used as an additive to jet fuels and as a deicer.

I put Sentry flea medicine on my female cat today at 12:30PM. By 1:00PM, 3/22/12, she was panting, eyes were dilated so I immediately washed the area and called the vet. They told me to bring her in right away. They gave her a shot around 4:30 and at 7:48PM, she is still acting strange. I gave her another dawn bath and I am waiting to see if I need to take her to ER. This flea product should not be sold. After reading all the cats that have died from this products, it should be off the market. Shame on you Hartz!

I applied Sentry PurrScriptions Plus as per the directions on the box to my 9-year-old male cat Cosmo at 10am today. Immediately, he did not like it on his neck, constantly trying to lick at it. About an hour later, he was acting very grumpy, I assumed because he didn't like that I put a foreign substance on him. I checked the application site, and there wasn't any redness or indication of irritation.

I bought FiproGuard for dogs and my dog had a reaction of itching and red spots. I bought it and thought it is the same as the expensive brand for fleas, etc. I am very disappointed in this product and will tell friends not to use it. It’s a waste of hard-earned money to protect my pet. Thank you.

I purchased this product, and used it once or twice as directed, without a problem on my kitten and adult cat. On the 2nd or 3rd use, I applied it in the afternoon, and by midnight, my kitten (7 months old) was scratching wildly at her back. We saw that her fur had burned (2nd degree burns to red flesh). We rinsed it with temperate water for several minutes, and she continued to scratch, and act as if she was being tortured for days.

On December 14, 2011 I gave my cat, Angel Baby, a bath with Sentry Natural Defense flea shampoo for cats. Angel was a healthy approximately four-year-old cat who I love endlessly. As per the instructions I left the stuff on her for 5 minutes and then rinsed and dried her off. As I rinsed the tub, I heard her cry and then she cried again. I looked out into the bedroom and there she lay limp and dying.

I purchased a Powzer Flash-N-Dash Ball that is supposed to flash on impact. However, the ball does not flash so I returned the product.

I moved into a small house with my significant other at the time. We had talked about getting a pair of cats, and after short period of moving in, we adopted 2 kittens. The house had a few problems with poor floor trim, resulting in minor ant infestations. Ants were a small problem that wound up getting resolved, but within a few months the cats developed fleas. Instantly, I reacted and bought Sentry Flea Formula at a local store. I did not read reviews and assumed this product was decent because it was a major brand; I was horribly wrong. I applied the liquid formula as instructed to the back of both cats’ necks. Both cats were obviously aggravated by their matted fur, but I assumed it was temporary and went to bed, albeit slightly anxious.

I have treated my home 4 times and working on number 5 tomorrow. I have used Frontline on both my dog and cat for the past 6 months and still have a flea infestation in my home. I've used Talstar and capstar and everything else I can think of to get rid of these fleas and still have them. I even doubled the product Talstar last time and still have fleas oh and I also used Borax on my floors and have treated every square inch of my home and guess what, I still have fleas! Is there and address for Frontline? Cause I sure would like it to send them an itemized list of what it has cost me so far to use their product that doesn't work! I'm really getting tired of these fleas and think maybe I should send them some with their boxes of Frontline that doesn't work. Sure think they would still be alive when they received them.

Sentry flea treatment for cats. Application of one tube every thirty days. Unfortunately, I cannot afford the higher costing flea treatments and I can't afford to take my cats to the vet (each visit is usually over 100.00 a whack.) My work has been affected by the recession and I virtually have no money. Both cats have different reactions, including irritated skin, fur loss and discharge from their mouths. It is extremely toxic and we can't seem to get rid of the fleas. It has caused a type of dermatitis to them both. Their eyes water and they are hiding. Worst of all, this product doesn't work.

Sixteen hours after applying one dose of Sentry Purrscriptions, according to the manufacturer's directions, to my 11 lb. 1 1/2 year old cat she began trembling, seizing, pupils were dilated, she was biting multiple clumps of fur out, lethargic eye movement, vomiting and diarrhea. After speaking with my vet, I was advised to bring her in immediately.

I applied Sentry PurrScriptions to both of my adult cats. The one is fine with 1 star rating. The other one is having major problems. He's showing signs of Neurological trauma, hallucinations, agitation, bloody stool, and aggression. The emergency clinic advised us to wash him which we did but has not helped. He continuously bites/scratches himself, bloody eyes darting all over the place and he's biting at the air. We are advised to watch him over 24 hours for signs of convulsions or seizures which means system failure.

For the first time ever, I saw a flea on my dear, sweet little Cockapoo, Ella Mae. I went to Pet Smart to look for a flea shampoo to use. The sales clerk highly recommended the Sentry Flea and Tick Oatmeal Shampoo. I used it as directed and Ella Mae went crazy. She started itching, scratching, and biting herself worse than before. I knew it had to be that poisonous shampoo.

I found a few fleas on my female cat and went to pet supplies here in Michigan. I picked up the spray, thinking it would be easier than bathing my kittens and also with the prescriptions squeeze on. I used the spray, and instantly, both my cats started acting strange. They both started foaming at the mouth and their eyes rolled in the heads.

After using this product on my three cats to treat a minor flea problem (ages 8 months, 1, and 2), one of them, the one-year old, received a bad chemical burn to the back of the neck. It caused his skin to flake and a lot of the hair to pull out very easily. I didn't use it very much, but only applied it to his neck, as the flea bath the week before seemed to work for the rest of the body (of course I didn't want to wash their face with it, so the fleas seem to flock there). He had the most fleas and I barely used it on the others who seem to be fine. After seeing the effectiveness of this product versus the potential risk, it definitely isn't worth buying. The essential oils in the product are toxic to cats and really should be avoided.

Our dog got a bad toxic burn due to use of their oatmeal flea and tick shampoo. The dog was in severe pain and their product caused serious illness to it.

I purchased two, three-pack of Fiproguard for cats. This product claims it contains similar ingredients as that of Frontline. However, after 12 days my flea problem became much worse. I'm not sure if Sentry doesn't use the correct dosage of Fipronil. In addition, I worked at a veterinary hospital for two years and I never had one customer complain that Frontline did not work for them. My cats are indoor, they have zero exposure to the outside. My environment was free of fleas, that is to say, the fleas were restricted to the pets.

My cat became ill after using Fiproguard for cats. He would not move and would just lie on the couch all night. There is an obvious problem with this medicine, and it should only be dispensed by a veterinarian and reviewed much closer by the government.

In reference to my previous review, I meant to state that I had my cat, Buttons, since he was four weeks old, not just since four weeks ago. This is why I am so heartbroken about him being murdered by this product.

I've had my cat since 4 weeks ago, who was 13 years old and in a pretty decent condition. He just had a physical exam a few months ago and the doctor said he was in good condition considering his age. Our three cats had a minor flea problem. They are inside cats, they had not had fleas since they were tiny. They did have flea collars, but they had expired without us knowing. We called PetSmart to see what else we could do aside from cat collars to deal with the problem. PetSmart told us to bathe them and de-flea them. We had de-flead a homeless cat before with Frontline. We went to the store to look for Frontline, had none, so they said the other stuff would be fine. So we picked up the Sentry Purrscription Flea for Cats and Kittens. We came home and applied it to our three cats, who are 13, 7 and 4. These are well-cared cats, who regularly get their immunizations, and who are all neutered and spayed. We applied it to the 13-year old first and decided to watch him closely because he was older, and it said on the box that older cats can sometimes have a slight adverse reaction.

I noticed my cat had picked up fleas from a hotel we were staying at. I went to the nearest PetSmart to get some flea medicine, and Sentry PurrsScriptions Plus was all they had left for adult cats. As soon as the liquid flea formula touched her skin, she seemed to be uncomfortable. After a few hours go by, she began hissing at the air, chasing after nothing, and itching worse than she did before. It was obvious that she was being irritated where the Sentry was put on her. I found this website and saw other people having the same horrible results, and that people said to wash the cat in Dawn dish soap. I did that as well as possible, and it immediately seemed to help.

Three of our five cats developed severe chemical burns. I told PetSmart, and they said that no one else has complained about this product. After reading some of your reviews, I find that impossible.

I had decided to use this product on my Bengal cat after he had minor reactions to chemical-based flea medications. That night, he started acting very strange, freaking out at nothing and running around. I didn't think about the flea meds, since it was also the 4th of July and I figured he was freaking out at all the loud noises.

I bought a Sentry "natural" flea and tick product to treat my dog. After the recommended dosage was applied, my dog began to have a negative reaction to this product. Over the next day or so, she began scratching uncontrollably and appeared very agitated (something she was not doing before the application). I bathed her in dish soap to remove the product and the scratching stopped. In addition to my dog's discomfort, this product did not kill or repel any fleas – the bath in dish soap removed the fleas.

I bought some "Sentry Purrscription Plus" flea and tick medication for cats and kittens, and proceeded to apply it to my 6 year old long haired cat as per the directions. My cat immediately reacted as if it were causing serious discomfort. He has started to act really strange and goes from sketchy to dispondent and lethargic. He started chewing on himself even more as if the fleas got worse. He has lost hair in little spots around where I applied the product on the back of his neck. He has had continuous diareha, although he is eating and seems to be drinking a lot of water which is good. It has been over a week now and he still isn't right.

We used SENTRY PurrScriptions Plus Flea & Tick Squeeze-On on our 4-year-old cat in April 2011. She was lethargic and "spacey" for a few days, and was obviously bothered by the medication on her back, itching, etc. We forgot the next month, but applied again June 30, 2011 (yesterday). Within minutes she was acting very strangely, spacey, hissing at toys, afraid of us. For a cat that is usually all over you for attention, being scared and jumpy with us is a sure sign something was wrong.

I purchased this at PETCO for my cat and applied it as directed on the packaging. Everything was fine, although, his fur had the product on it for five days. On the fifth day, it seemed gone. Yay! Until a few hours later, his skin became red and irritated. Now, he is missing some fur and he appears lethargic. I have washed the area, but I am scared that he will get sicker.
