Hartz Mountain Flea & Tick Drops Reviews

I washed my dog with Hartz Oatmeal shampoo. After 2 days applied the Hartz Flea and Tick Drops to the small of my Pit Bull's back. The very next day she was vomiting and lethargic and would not eat. On Saturday My Family Friend died due to the use the Hartz Flea and Tick medication. @ different Veterinarians confirmed this. I do Not recommend any products of HARTZ.

I put the flea and tick on my dog yesterday and when I went to take her our today in the afternoon I seen this terrible bloody mark on her and I was immediately like wtf, so I call the place and they go on abt "Thanks for calling us and I'm so sorry this happened. It's very rare that this happens," and gave me a case number. "Oh and take her to the vet too." I cannot afford a vet and now I have no choice. Me and my husband are very upset and worried bc I seen all the reviews abt pets dying and I feel so bad for applying it to her. So anyways I also noticed her collar has been extremely corroded and the burn is spreading farther down her neck. Getting worse by the hour.

I put this on my 8.5lb cat and she instantly began having a reaction!! It burned my eyes instantly and she acted like it was burning her! She was panting, and meowing strange, running around, and meowed when I tried to touch her. She ran and hid under our bed and when I got her out she kept trying to turn her head to get the product off. I knew I had to get this off of her immediately! I washed her with Dawn and she seems to be ok, as of now, but will continue to watch her. We can only hope there’s no permanent damage done to her neurological or nervous system, skin, or that her hair won’t fall out-which is the least of the worries after reading some of these other reviews on here!! Luckily I only have one cat and only had it on her for less than 10 mins, I would hate to know the outcome if someone doesn’t watch their pet for reactions!!! Definitely need to evaluate this product as it seems to be incorrectly dosed and way too strong for small animals.

So where's the class action law suit for this?! Everyone on here has suffered greatly from this product and after putting this on my 3 cats one has no hair and twitches and the other 2 I've given multiple baths, I can still smell it, it burns my eyes. I can't believe that this is even allowed and there are enough people here to start filing claims. I am willing to help however I can but if anyone here knows more or can help please let everyone know! These people deserve money for pain and suffering. This is unacceptable and animal cruelty!!! My animals are all I have and depend on me to care for them. They are more special to me than anyone and this is a nightmare!! Someone please help!

I put this medication on my 3 cats. Immediately, the started foaming out of the mouth and seizuring. I rushed them to the vet. $600 to wash them down, stabilize them and pump them full of medicine. 2 of the cats are still having neurological symptoms, shaking their hind legs uncontrollably. Horrible. Please please take it off shelves. You should be so ashamed!!!!

Purchased this flea & tick for both of my Jack Russel's and the cat version for my boy cat. Immediately, my cat ran all around the house, all over the furniture, twitched all over, was uncomfortable being touched, hid all night behind things, stopped eating and drinking. It took three days for him to finally feel better. My Jack Russell began violently shaking, her heart was racing, she could not lay down, ran into everything, appeared to not recognize her surroundings, growled, and stopped eating and drinking.

I placed the Hartz drops on my border collie. He became violently Ill... Drooling..unsteady on his feet.. Loss of appetite..nausea...lethargy...itching...blistering skin that bled...excessive nervous..panting and accelerated heart rate.. Fortunately he survived. This product is dangerous and needs to be removed from the markets.

I bought this product labeled for dogs weighing 31-60 pounds. There is A lot of product in the tube. I did not want my dogs exposed to that much poison. Rather than using one full tube for each of my dogs. I modified the dose from one dose per tube to 4.5 doses per tube. It is just as deadly to fleas and ticks and is safe for my dogs.

We put this products on our cat as directed and within 24 hours his fur was gone and the skin was burned and bleeding. We cleaned it off as soon as we noticed it. We will never buy from this company again after reading some of the other reviews similar to our issue.

I put this product on my cat and it does not seem safe to use. There was so much of it. I placed it between the shoulder blades and her eyes were burning and the smell was so strong. I will never use this product again.

I have used the Ultra Guard (purple tubes, not the Pro), in the past and it was inexpensive and it worked as they said it would. Usually lasting 30 days. I have 7 cats. I previously had a problem when the topical medicine was applied and latter added a flea collar maybe 2 weeks later (bad idea). One cat out of 7 got a little sick, removed the flea collar and he recovered. This June I began using the Ultra Guard Pro as the cheaper stuff wasn't available. It didn't work at all. 3 days after application all my cats were infested with fleas, worse than ever. After 5 days it was even worse. After 7 days only a bath worked. On day 10 fleas still infesting. Day 15 another bath. 1 cat later died of flea bites, or over exposure to medicine that didn't work after ripping itself raw. Yes the fleas can infect the animal too or excessive bites cause anemia which can cause the animal's organs to shut down. This product is horrible.

I applied Hartz flea drops to my 62lb red nosed pit bull, which is a very sturdy dog, and she won't move and is breathing very slowly. I have to take her to the vet!! This stuff is poison and my baby better not die! How can they still sell this crap if it's poisoning our pets!?

Hartz Products harm animals! We bought the flea and tick Ultraguard for our cat and a few days later I found her dead. She had had a seizure. This product needs pulled off shelves! If it was killing children, there would be a recall! What do we have to do to get rid of it?!!!

My experience with the company is very very poor. I put this medication on my cat Lilo and within 30 minutes he was disoriented and then less than 20 minutes after he started having seizures I almost lost him. Had to rush him to the doctor and now he is on seizure medication for the rest of his life. His motor skills are messed up. His century is messed up. He is scared of everything now and all he does is sleep. He used to be an active chap. Not scared of anything. My opinion this should be took it off the market. Don't want no other to go through what I've been going through. Thank you.

My cats have been scratching themselves the past couple of days. I checked them and they had fleas. I found Hartz flea treatment at the store since I couldn't afford the top notch medicine. The package was Hartz Ultraguard pro and it stated it killed fleas in 15 minutes. I squeezed the solution on my cat's neck and within minutes, she started to scream and hiss, running all around the house. Hissing at the other cats and I. I figured it was because of the smell and her first time having a flea treatment. A couple hours later, I found her panting, scratching at her neck and hissing all in one. I looked up the medicine and found this medication to be toxic! I immediately gave all the cats a bath in Dawn dish soap. The following day, my cat is being a loner and not Socializing very well. I hope this product doesn't kill my frickin' cat!!

Hartz flea spray killed our 4-year old kitty. My 7 year old daughter is devastated. I am extremely upset that I was unaware of the hazards on using Hartz brand flea products. Hartz uses insecticides/pesticides that are poisonous to humans and animals. Hartz obviously doesn’t care. Victim pictured.

This product is absolutely horrible. I bought it on the 29th of last month and it is now just the 12th of September and she is infested in fleas and has been since the day after we put it on her. She's miserable. She's scratching everywhere. I have flea eggs dirt everything in my bed. This product is horrible. If I had the receipt from Walmart I would request my money back. Anyway I don't recommend putting this on your pet. She was lethargic for a couple of days after we put it on her. We put it on the outside dog and our little min pin and all three dogs acted the same way and all three dogs are covered in fleas I mean covered. I'm enclosing pictures. Bobbie **

I switched to this brand and my cat ended up having a seizure. My baby almost passed away from a flea medication treatment. This product is terrible!! I even have it on video. I would never recommend this product.

Not only does this product not kill or prevent fleas, it made my 4 month old kitten seriously ill. She became lethargic and stopped eating. I tried to save time and money by grabbing this product while grocery shopping but it ended up costing me one giant vet bill. My bill actually says, “1 Exam (General) Hartz Toxicity” $65, and that’s not including the medication needed to counteract the side effects. The vet said she sees it all the time with the Hartz brand and wishes they would take it off the shelves. Please, please please don’t poison your cat and please warn others. I almost lost my sweet Potato.

Applied this to my 2 year old cat who behaves very well. Immediately the smell was so strong and smelt like super glue. He starts hissing and growling and running around which he never does. We immediately tried to get it off and he was not happy, not trusting us anymore. I think if it would have been on any longer it would have seriously hurt him. I dont know if it was the formula or smell that made him go crazy but this product should not be on the shelf.

As soon as we put it on our cats, one of them hid under the table, we offered him his favorite treats, he would not eat them. He jumped out the screen door and went on the hillside. We caught him and gave him a bath with Dawn dish detergent, twice. The other two cats were fairly okay, but they kept scratching their fur where we had put the drops. We gave them baths too. Thank God our three beautiful baby boys are okay. Never use Hartz, you may get a good deal, but is it worth your pet's life? I may update if any other effects happen tomorrow.

This shouldn’t be sold in stores. It needs to be immediately pulled from the shelves!!! I had a vet appointment and dropped 250.00. Being short on cash I passed on the 80 flea and tick, and figured I could do it myself. When my dumb** saw 11 bucks for this product I thought I was getting a steal!!! Little did I know I was giving my cats a death sentence! I put a treatment on both 10 pound cats. My white haired cat immediately looked shocked. I knew something was up. When I saw her neck it was beat red! Not to mention the smell of the treatment was making me nauseous, I could only imagine how she felt. Her skin was burning.

Your company is the worst company in the world. My cat died a month after I put your flea & tick drops on him!!! He became lethargic, anemic, started always hiding, not eating or using the bathroom!!! And I woke up one morning and he was dead in his bed in the living room!! I hope you people burn in Hell!!! Murderers!!!

My dog (Maria) ran around outside and got a tick and Flea issue. At the pet store, this was the only brand that was still available and I was desperate because of her condition so I decided to try it. Maria became very weak and couldn't walk shortly after I used the spray on her. She also refused to eat anything even when I spoon-fed her. She also got really sick and stopped responding when called. The other dogs were whining and crying at me the whole afternoon and wouldn't go near her. They never behave like that so it was cause for concern. I looked up the dangers and reviews of the product and was mortified! I immediately gave her a bath and she slowly started coming around. Why is this product still available? This is detrimental to the health of pets. Recall this product at once. Absolutely horrifying. Shame on you. Never again!!!

My husband sprayed our dog with this spray and our dog immediately dropped down to his knees and went into a seizure. Thank God immediately my husband put our dog in the tub and washed him down. Thank God he was OK. After using it I told my daughter and she told me about all of these reviews and I came on to read the reviews. I wish I would’ve seen this first never would’ve bought it! Not sure how they can still sell this product.

Bought this product for a cat I've only had 7 months as protection for her from fleas & ticks. Within hours she acted like the was spooked like the didn't recognize me. She was so uncomfortable, listless, nauseated. Days later she is still not herself. Eating very little. How dare you continue to sell this product to consumers??? Remove the product from the stores.

If I could give this negative stars I would! Not even 1 day after putting this on my dog and following instructions exactly my dog became very sick - diarrhea, extreme vomiting. He can’t keep anything down - not even water. His fur is falling out and he’s had 2 seizures. My local vet has had 2 cases where the animal has died in the past month because of this medicine. He is currently being treated by the vet but no results as of yet. God forbid if anything happens to my baby I will be looking for some type of responsibility from this company. Do not use this product. Yes it is cheap but you get what you pay for!! In my opinion it shouldn’t be on the shelves anymore. Please look after your fur babies and don’t use this product!!

We have 2 litter mates that we put flea collars on. One cat kept pulling his off, so we got the Ultra Guard Pro topical. He became very ill, wouldn't eat, hair falling out and listless, hiding in the basement. I came here, read the reviews, and saw that Brittany of Manteca, CA, suggested Dawn and vitamin E. He wasn't crazy about the bath, but it worked! Within a day, he was eating again, and within 2 days, he was back to his old self. The cat with the collar never got sick, but now he's gotten rid of it somewhere. I've learned my lesson and will never use this again. Thank you, Brittany, for saving my cat!

I purchased Hartz Mountain Flea & Tick Drops from Walmart because they were cheap. I was using it as a preventative measure to keep my dog from getting ticks because it's summer time. I followed the directions exactly, and within minutes my dog, Bella, began to run around scratching at the ground. She would roll her head and back against everything and would not stop, almost as if she was burning. I figured she was having some sort of allergic reaction and quickly googled the reviews. When I saw all of the horrible reviews, I decided to immediately wash her. I scrubbed her down twice now. She's sleeping now and seems better after the bath, but if any further symptoms occur I will make sure to have this company pay for hurting her. From the reviews and my own personal experience, I would not recommend this product and I even believe it should be taken off of the market.

This product needs to be taken off the shelf. I used “Hartz UltraGuard topical flea and tick” prevention and it made my cat begin to pant and drool profusely. She began to walk around the house, staggering w/ her mouth hanging open. After about 20 minutes, I put her in the bath and scrubbed her down, got her out and held her for a little bit. Towel dried her and now she is slowly coming around. I will not ever buy any Hartz product again.

I used the Hartz Ultraguard flea & tick prevention for cats on our shop cats last week on Thursday, and almost immediately they both started acting strange like they were "running" from the feeling of the drop on their backs and I worried it was burning them, but I decided to let the product dry and see how they were doing in the morning. They still seemed uncomfortable on Friday, but I didn't think to wash the drops off at that point. It is now Monday and my boys are BALD where I applied the drops. Bald! Clumps of their hair are still falling out every time they scratch or when I wipe them down. I've spent the majority of this morning trying to help them. Hartz info line recommended I wash it off with Dawn dish soap and apply vitamin E oil, but they deny any fault in their product, saying the hair loss is a "normal" reaction. Frankly, this product is not safe for your pets and I regret using it in the first place.

Do not use this product as it can cause imminent death to your cat or dog. This product is a poison, it is clearly on the package. It states what is product is toxic to your animal!! Only wish I had read the reviews, and the packaging clearly prior to putting it on my cat and dog. This company should be put out of business. I am asking everyone to come together and start a petition for a class action suit. This company is harming our pets who are family members. No different than Johnson & Johnson did by not warning women the chance of cancer but I believe that this company will be protected because they clearly states on the package that this product is poisonous and toxic to our animals and also humans.

Wish I had read the reviews before subjecting my cat to this horrible product. I washed it off after 20 minutes and caught him scratching profusely. There was a red irritated spot where I applied the product. He is out of it; a very scary outcome for a product that is supposed to help keep them safe from ticks. I will return the two vials of product and also return the ear mite product I did not use and WILL NEVER use Hartz again! I will tell everyone I know who has a pet of the dangers and never recommend anyone associate Hartz with “pet care." I am one hour into this and hope the outcome goes well for my cat.

My dog has been sick since Thursday night, a couple days prior to this we bought & applied Hartz flea medicine on him. As we have sat here Googling every possible thing we could to find out what was wrong with him with none of it making any sense, as I have literally stayed up all night last night with him watching him throw up violently & repeatedly all night, more than positive knowing he was dying on me a couple times & all I could do was cry & pray that he didn't. This morning we looked up the reviews on this flea medicine we put on him before he got sick, it is mind blowing the things I have read. He is a little better than the rest of the night has gone but not good at all, still a long way to go. He is very sick & I am more than positive it's from Hartz flea medicine we put on him.

Only have 1 star cause have to pick. But I do not even give it 1 star. Two hours after using this product. My dog started throwing up. She won't eat. Been 5 days now. She still hasn't ate. Tried everything. If my dog dies I promise the company will hear from an attorney. Especially with all these bad reviews.

Do NOT use this product I used the Hartz ultraguard pro and instantly my cat started acting a little weird, didn’t want to eat, didn’t want to go outside and just wanted to sleep... He always plays with his laser and didn’t even want to look at it. I felt like something was wrong and then I looked down and he had vomited after 4-6 hours the poison was on him. I immediately took him in my bath and washed him very well with Dawn. The next morning he still was looking pretty weak, didn’t want to eat or even move so I took him to the vet and he was running a super high fever. Thankfully they took him and hospitalized him to get fluids and check his blood work. Blood work came back really good and the fluids will knock down his fever and get this poison out of his body. NEVER USE HARTZ. IT'S POISON!!!

This product does not work and made my dog and cat sick. Total waste of money. Very upsetting. DO NOT BUY THIS PRODUCT!!! My cat got irritable and stopped using her litter box. My dog started throwing up and to top it off it did not even work on the fleas but made my fur babies very sick!

24 hours after putting the flea/tick med on my dog he was lethargic, throwing up, diarrhea and overall sick. He looked like he was there but in his eyes he wasn’t there. I immediately washed the medication off of him and my other dog even though she had no symptoms. I didn’t sleep at all because I wanted to be up with him because he couldn’t sleep at all! I was terrified he was going to just fall out! Thank goodness after a couple of cool baths, and lots of fluids he seems to be coming around. NEVER AGAIN! This product should be banned!

Upon application, my poor cat immediately began blinking and drooling... stumbling and shaking. Eventually he ran off but stopping periodically with convulsions. I feel so relieved he even survived this product after reading the other reviews. This product is far more terrifying than any fleas could ever be- DO NOT BUY OR PUT THIS PRODUCT ON YOUR PET AT ANY COST! It is truly dangerous and should be removed from the market immediately!

I used this product on my amazing CopperPot, only 5 yrs old and other than the ear mites, a very healthy cat. And although he didn’t have an immediate reaction, 2 days later he became lethargic and very irritable, he wouldn’t drink, eat or use the litter box. I gave him water and fed him blended eggs and salmon with a dropper, knowing if he didn’t eat or drink he would die for sure, and he finally went to his litter, I followed him. It was then I noticed blood in his urine. Scared and confused, I took him to the vet. His kidneys has shut down and he was in renal failure and treatment would be upwards of 600.00. The vet refused to let me make payments on his treatment, even as I begged her, she refused. What she did say she would do is take my cat, and treat him, but only if I surrendered him to her.

I have used this, 1/2 of a dose on my sweet 5 years old Mollie cat tonight, within 5 minutes she was running around twitching her legs, crying out, hiding, drooling, panting, my kids & I were scared to death! I called my friend because I had used this one time before 1/2 dose, she said to wash her immediately with Dawn soap. She was about to have a seizure, I frantically got her started washing & washing... 3 hours later she is calm. Has eaten a treat. Praise the Lord! I was so scared she was in bad shape! Don’t use this product!!!

I bought this product for my cats and one of my cats had a severe reaction to it. It burned her skin. And the other the collar did absolutely nothing. It does not kill fleas. I don't know why they can sell this product. It's absolute trash. I'll never buy anything from Hartz again.

Should have consulted my vet first, but I grabbed a box of this Ultra Guard Pro along with some groceries, thinking I would save myself a second trip to a pet supply store. I read the directions carefully and even the pictures showed how the topical solution should be applied. IMMEDIATELY, my cat started twisting, trying to lick it off. I quickly applied a dry towel to the area wiping off all that I could. Well thank God I did! The next morning my poor cat had a bald spot with dried blood on it. I medicated the sore for a few days & although my cat doesn’t appear to be in any pain or discomfort, his bald spot is getting longer & no hair is growing back, in the affected area. So furious & irate, now I find all these complaints, on this site. I called the store manager at the Walmart I purchased the box from, and complained. I found my receipt & returned what was left. Just like the others, I’m shocked this product is still in the market!!!

I just used the drops on my 2 cats and within 15 minutes they were wailing with pain and terrified. I couldn’t get them in the shower but I was able to wash off most of the medicine. Now I’m sitting here watching them try to calm down and get some sleep and not knowing what can happen in the next hours. I now have to lose a day from work to take them to the vet. Why this company is still in business is beyond me.

My cat Kip is a 6 yr old longhaired female. Not her first time using product. She was badly burned between shoulder blades...huge bald spot. Her fur is falling out...big bald streaks above both all the way back to ears. I'm not a happy mommy! Someone needs to be held responsible for our pain and suffering. My cat is traumatized as I am.

I applied the first tube of flea drops to my 2 year old healthy cat and I found him dead 40 minutes later. I never even saw him exhibit any signs that he was ill from the drops and he was acting normally prior to applying it. My vet told me he's seen other pets die but when he contacted the company they had told him there weren't enough reported deaths to warrant pulling their product. I went home and threw every Hartz product in my home into the trash! Pets are like family to my children and me. Losing our Sabo so suddenly like that dealt a blow!

Please do not use this product. I don't even know why they sell it. It's very harmful. As soon as I apply a tube on one of my cats all three of my cats they all immediately started acting like they were trying to get the stuff off of them so soon as I seen that I went to go wash it off and they're better now but I will never use this product again and I suggest no one else uses this product.

I'm sitting here right now watching my dog die because of this HARTZ product! He is only 6 years old! He is my daughter's service dog and she is a mess over this! He is drooling and has diarrhea and is very lethargic. He hasn't eaten in 2 days and he looks like he might be even going into convulsions every now and then. The vet had already told me he'd heard of this happening with Hartz products and have been telling all his patients not to use them! I was told it's too late for my dog so I'm waiting for the office to open so I can bring them in and relieve his pain. But because of the pain this company has given me and my family I will have no forgiveness for them! THIS IS SO HEARTBREAKING FOR A HANDICAP CHILD TO LOST HER SERVICE DOG IN SUCH A WAY SO SOON!

My cat started drooling profusely, meowing and acting very sick. I washed it off as best I could. She is some better now, but will not let me hold her. I think it almost killed her. I will never use this product again. She still is not acting like herself. I applied it as directed. Do not put this on your pet. She seems disoriented.

I have used this before without any problems. This time she is extremely uncomfortable. I have given her 2 baths and she is still not happy. I will never use this product again. Save your money and your dogs.

2 days after application I came home to find my 8-month-old large, healthy kitten in bathroom violently scratching wound on head. The flea guard I put on Bear to help him caused him to scratch away his own skin. I would never recommend anyone use this on a pet they love. I couldn't afford emergency vet fees. I tried to wash sore with sterile water but he kept running from me. Has been eating and drinking. Not scratching constantly now. Seems some better except for bloody raw sore on back of head and neck.

I just put this flea treatment on my cat, and about 10 minutes later he started shaking really bad and drooling profusely. Then he peed on the floor which he has never ever done before so I grabbed him and put him in the bath, when I was washing the treatment off I noticed he was bleeding and it gave him a chemical burn! Please do not use!

I applied the product to my Maltese & to my Bichon Frise, today. Nine hours later, not one flea has died. Weeks ago, I tried Hartz flea shampoo. It didn't kill one flea, either. I'll never trust this brand again.

DO NOT USE!!! Applied Hartz flea med to my cat between her shoulders, the next day she was lethargic and hiding. She stopped eating and I noticed fur was gone where the Hartz had been applied. Took her to the vet - luckily she is not poisoned. DO NOT USE!!!

I will not mince words. THIS ** STUFF SHOULD BE REMOVED FROM THE MARKET AND A CLASS ACTION LAWSUIT FILED. I applied this product to my 3 cats and within an hour one began running around the house screaming until it collapsed in a series of epileptic seizures. The poor little thing urinated and voided its bowels during one of these fits. The second cat had exactly the same signs and symptoms to a lesser extent but now appears to be STONED and unable to walk without falling over. My third cat... thankfully... showed only minor effects, mostly lethargy and lack of appetite. My sons began crying and looking for me to aid. They do ANYTHING to stop the pain of their "friends". Unfortunately I do not have the $1,200 to $1,800 I was quoted to have all three cats stay at the Vet to receive treatment. Hopefully time will be enough to heal my cats from this ** POISON.

So I learned, the cheap is the most expensive, and the guilt I feel because of trying to save some cash I almost killed my pet doesn’t have any price. If you care about your pet never ever put anything of this brand even close to your house, is pure poison. My dog survived by a miracle I think, after a kind of hell she is recovering and just in case she has got an appointment with her veterinarian. I feel so bad. How is possible this thing is in the market? So if you want to prevent your dog from fleas and save you can kill him? No way again. Check this product in Internet, you will find scary stories left and right, so NEVER USE THIS THING IN YOUR PETS.

After applying to my cat, and not even the whole tube, she started panting and running around the room like she was trying to get away from something. She was breathing very fast. I decided then and there not to use the rest of the tube and set it on my bedside table. The next day, there is a mark on the table where this product ate through the finish on the table. Never again. Thankfully my cat seems to be ok now. Will not use or recommend this product or brand to anyone.

This product made my roommate's cat convulse which we thought was just an allergic reaction because my cat seemed fine after application, but now it's 3 days later and my cat has a chemical burn where it was applied and she's in pain, and I now have to take my cat to the vet for treatment. I DO NOT recommend this product!!!

I used one tube this product on my average, 2-year-old healthy cat a couple weeks ago. He became lethargic shortly after and stopped eating. Now he is at the vet, severely dehydrated and underweight from chemical poisoning. Hartz customer service has not responded. A $10 tube has brought $400 in medical bills, and they have told me he might not make it. If they kill my cat, I'm going to sue. !!!BEWARE!!!

Our cat, Tiger, developed a flea problem during the summer. We bought Hartz UltraGuard Topical Flea and Tick Prevention. It didn't seem to work to speak of, and we noticed that Tiger began to act strangely. He stopped eating, and began to either just lay about or be very restless. He gradually got better, but I would not recommend this product. I have since read that the active ingredient makes cats sick, and in several cases has resulted in death.

I'm going to keep this short and to the point. If you love, I repeat, if you love your pets, don't "ever" use Hartz line of flea products. My beloved cats could've died. One ended up with chemical burn, the other had seizure like symptoms and hyperventilated. I was scared of losing them both but by the grace of god, they survived this toxic poison they call flea drops! Never again! Thinking of a class action against them, this stuff needs to be taken off shelves everywhere!

Our dog is now on her deathbed due to this flea medicine. Do not use. It will severely hurt or kill your pet. Our dog is extremely lethargic and got an infection due to the medicine. We took her to the vet and without thousands of dollars of what we don't have she will die so we are just waiting for her to pass on. We have had her for the past 7 years. Extremely heartbroken and it's all because we decided to use Hartz Flea and Tick drops.

Sadly, I was very disappointed in the product. Bella??? is a long hair and weighs 12 lbs. indoor cat but, I carried a flea from outside. I used a tube nothing. Much dismay I waited, A couple of days itching, licking etc. I dosed her with a little dab more. I won't buy this again. We aren't infested or have had a real issue. It was more precaution.

DO NOT USE HARTZ FLEA AND TICK ON YOUR BELOVED FURRY FRIENDS. I just used Hartz flea and tick droplets on my cats. One of them began immediately meowing in pain, and became extremely lethargic. The other began foaming at the mouth and then meowing in pain. I immediately bathed them both and the symptoms are getting better, however I would NEVER use this brand again. And would have never used it in the first place had I glanced at the online reviews. This is infuriating that Hartz is still even in business considering the plethora of negative reviews and adverse reactions to this medication.

Don't use HARTZ ULTRAGUARD PLUS FLEA and TICK MEDICINE ON YOUR CATS. Jake just wants nothing but lay in my lap mostly and slept for past 2 days. This was his 2nd time with this. I should've known it was the Hartz that did the last time. I washed it off but he's still really lethargic. POOR GUY.

AVOID THIS PRODUCT! Today I applied Hartz Mountain Ultra Guard Plus Flea & Tick Prevention to my cat Sophie, in between her shoulder blades as instructed by the company's directions on the label. Within 10 minutes she was hyperventilating, lethargic, and suffering from what appeared to be a burn all over her back. After a $200 emergency veterinary visit, Sophie was diagnosed with a severe chemical burn from this product. If it is possible I will GLADLY take action against this company for producing and continuing to produce a product that is toxic and life threatening to the customers it claims to serve. Avoid this dangerous product.

Bought this product at Walmart because my dog and cat kept scratching because of the flees. Soon after I applied it on my 6 year old cat she started pacing around the house, super weird. I started reading reviews and realized she was having a bad reaction to it, so I grabbed her to shower her (she don’t mind showering). She started screaming and went bathroom on herself. As soon as I washed that nasty stuff off of her she relaxed. Hopefully that was that and she’s ok now. I washed my Pomeranian right after. I’m not taking any chances! Wish I would have done research like I always do.

I used this product on my cat because he got fleas really bad. I didn't have the money to get the top of the line stuff so I settled for this and figured even if it didn't kill all the fleas, it would at least help some. After treating my cat, he started vomiting and having seizures. He got very sick so I took him to the vet. The vet told me he was surprised my cat was still alive. Kind of ironic. I bought this product to save money and ended up with an $800 vet bill. Do yourself a favor and just spend the extra money on something that won't kill your pet.

Pls don’t use this product. I put it on my cat to prevent ticks and fleas and within 2 days, my cat's fur that was under the collar was completely gone and her skin burnt. Clearly this product is full of nasty chemicals... I’d rather have my cat have fleas than burn her like this collar did. Spend more money on an actually decent product that won’t harm your pet.

About a month ago I put Hartz Ultra Guard drops, nothing happened. I tried again. Well they hated having the medicine put on them, but I got it on them, No difference. Three days later they can’t even sit still, scratching and licking like crazy. I previously had two cats in PA. The medicine worked fine on them. I just don't understand what happened. These two are smaller than the ones I had in Pa. It just didn't work, so now I need to wait to put anything on them. It’s not as expensive but when it don't work, it’s money I don't have wasted.

It is 11 pm. I gave my cat the drops at 2 pm. She is twitching, her skin is rolling, she has been hiding. I noticed her acting different. Not lovable as usual. I called the emergency vet hospital and they said she is having a seizure. She will possibly die. I'm praying so hard that she doesn't because I'm seriously going to take action. DO NOT USE THIS PRODUCT. IT'S CHEAP BUT WILL COST YOUR PET'S LIFE.

I used this product on my dog and it absolutely does not work. I followed all product instructions and it did not work. I do not have a flea infestation yet still I find an abundance of fleas on my pet. I do not recommend this product for anyone. The only recommendation I have is for this product to be taken off the market and I wish I could get my money back. This product is a total snake oil scam.

Bought Hartz flea drops for my cat at Walmart because of price. I figured any product sold at Walmart would be safe for my cat but boy was I wrong about that! Ever since the day I used this flea product on my cat for the first & last time he has been stricken with horrible seizures. The seizures have caused him lots of pain & suffering, and losing use his back legs. Once again our government has failed us, & let some big company dictate their decision-making process.

Wow, I wish I had read these very helpful reviews BEFORE putting Hartz Ultra Guard on my two adult male cats! Within a few minutes after putting this medicine on both of them, the 3 year old started running at top speed throughout the house and was alternately agitated, howling, panting, and sneezing! He has never reacted to flea medicine in this way before! Between his bursts of running, he would collapse on the floor looking completely lethargic. I immediately called the phone number on the package, but the recording said the business was closed for the weekend and directed me to another "Health & Safety" phone number.

DO NOT USE THIS POISON ON YOUR FUR BABIES!!! I used this product on my adult cat. He's approximately 12 lbs. Within twenty minutes he was yowling in pain, refusing to move, not allowing us to touch him. I was certain I had just accidentally killed my fur baby. I quickly looked at the reviews and thankfully bathed him in time to get it off. This all happened within the last hour. He seems much better now, and more like himself. A Little traumatized, but good. DO NOT USE THIS PRODUCT ON ANY ANIMAL!!! IT IS AWFUL!!! Need to be recalled permanently!!! Hartz is evil and unprofessional to continue to allow this product on the shelves. Animal cruelty is a horrendous act!!!

I purchased Hartz flea medication for my 2 adult cats. The medication (Ultraguard Topical Flea & Tick Prevention for cats and kittens) is for 5lbs and up. My 10lb cat fell ill first about 14 hours after application. Her head hung low, her pupils were dilated and she was obviously in physical pain and wouldn't eat or play (she always loves to play). She kept twitching her back hair and shaking her head and ran away when we tried to touch her. I took her to the vet and after I got home I noticed our 17lb cat was beginning to have symptoms.

I wish I would have thought to read the reviews before I ended up torturing my cats with this product! This was the only flea drops Walmart had on the shelf. After 10 minutes of applying this to my cats they were panting, drooling, wobbling, scratching, and growling! I am absolutely beside myself knowing that I inflicted this pain upon my babies. I washed them as best as i could. They are both hiding now and highly irritated. I hope they are ok. I will be calling the vet in the morning. This product should be removed from the shelves!

Please NEVER use Hartz Dual Action. I put it on my dog, within 24 hours she was having seizures. We bathed her immediately when we noticed this, it was in her system too long. After 12 hours we noticed she was not the same. She couldnt walk, she wouldnt go potty, she wouldnt eat and she was never her bubbly self. I picked her up to take her outside and she died in my arms! I am devastated, she was in excellent health until I used this product on her. Hartz, you should be ashamed that you have this product on the shelf. BEWARE consumer, if you love your fur baby stay away from Hartz products. I buried my baby yesterday!

Gave Hartz flea medicine to my dog on a Friday afternoon. By Sunday afternoon, my dog was at the vet. My vet did X-rays, blood work, ultrasound. They sent him to emergency vet who then gave him charcoal around the clock, an IV for 2 days and muscle relaxer for his facial twitching. Please do NOT use this product. It is a poisonous toxin that is NOT regulated. The company should be put out of business for harming our pets!!!

I will get straight to the point… This product is absolutely horrendous! Last summer, I treated my cat with this product as the fleas in our area were at an all time high. Within an hour of treating my cat, he was throwing up and having a seizure. It was terrifying! I was almost certain that I had killed him. Like many of the reviewers, I also was advised by my vet to immediately wash him with Dawn dishwashing soap. I will never buy another Hartz product again. It only stands to reason, that if your company specializes in products for pets, that you would test the products thoroughly and immediately removed from the market any products that are harmful; anything less than this is inhumane! Please speak to your vet about a suitable product for your cat and stay away from this over-the-counter nightmare.

My cousin sent her husband to go get flea meds. He bought Hartz flea drops instead of the usual flea medicine. My cousin applied it as directed to both cats. One is fine. That's the older cat. But her 5 or 6 month old kitten maybe a little older developed a scabby rash. Greenish kinda scabs but she itches it a lot. It was chemical burn from the meds. I am very upset about it. It did not really help the fleas at all. Of a scale of 1-100 it's a ZERO. I will never buy Hartz again.

Not everyone can afford the prices at vet offices. I have a rescue dog and cat. We use Hartz (Pro Guard Flea and Tick Treatment) on both. We have never had a problem, and find the product to work quite well, and we live in Florida, so we have a flea problem almost year round. I would recommend this product to anyone. Although, we may have limited means, we love our furry friends, and want to give them the best. Hartz provides that. So, thank you, Hartz, for caring about all animals.

I decided to adopt a dog from Puerto Rico and before being able to take him to New York needed him to pass a vet exam and make sure he was rid of any flea and tick. We applied this and a few days later while at the vet he had a focal facial seizure. The vet then informed me it could be distemper which I knew wasn't the case because he was around other dogs who didn't have it. They told me because of the distemper we might have to put him down. They gave him meds for a bacterial infection and a few days later he was fine and I could take him home. Because of this product, I almost put my dog down. I didn't make the correlation until I spoke to the vet that had informed me that this isn't a one-off case and it happens with this product. I will never use this on my dog again! This shouldn't be legal to sell... I have a video of the seizure in case anyone wants to see a heartbreaking video.

I put the cheap $5 "Dual Action" Flea & Tick drops on my 45 pound Border Collie and I'm pretty sure it made her sick. She's a tough cookie and she was throwing up in my bedroom not too long ago which is really unlike her. She has gotten away eating chicken bones many times. But this stuff seems bad. She's also panting and seems to be overheated. I just gave it to her earlier today and after reading these reviews I don't think I will be risking it. She is foaming a little at the mouth...

We used Hartz Ultra Guard Pro Triple Action flea and tick drop for dogs and puppies on our 9.6 lbs Shih Tzu. About three hours after applying the drops our dog was unable to walk, had a constant head tremor, wouldn’t eat or drink, and wasn’t using the bathroom. The next morning he wasn’t any better so we bathed him with Dawn dishwashing soap. A few minutes after the bath he was walking around and perky again. This Hartz product is dangerous. I don’t recommend using it. Small pets may be more vulnerable to adverse reactions from this product.

On Memorial Day we took our dog a bath with Hartz Flea and Tick Shampoo. 3 hrs later our dog started to shake, throw up and could not walk, would not eat or drink. We took her to the vet and we were told she had been poisoned. Of course we were in such distress we did not recall the bath. However, vet bill was crazy but she made it thru. However, still left us wondering what did it. She is a inside dog so we were very confused. Today I see my cousin post of her dog after bath with Hartz and sounded the same so I agree this should no longer be sold.

Last night I applied Hartz Ultraguard to my 15lb 3yo cat. Within 6 hours he stopped eating, wouldn't drink water and wouldn't play with his toys (my cat is very playful and always wants to eat). He wouldn't let me pet him or hold him. He didn't have any interest in anything and he just hid behind the couch. I did a lot of research and read to give him a bath with Dawn dish soap, within 10 minutes he was eating and playing again. DO NOT use this product on your cat. Many cats have died. Yes it's a cheap product but I'd rather spend more money and have a cat that is alive.

I bought Hartz Flea and Tick Spray for dogs - supposedly kills fleas and tick for up to 7 days. Took the family on an outing and made sure to spray the dog really well. She still got ticks and they did not die. I had to remove ticks burrowing into her! DO NOT BUY THIS SPRAY!

I have used this product for about a year on my dogs and it is effective in the treatment and prevention of fleas and mosquitos. There are a lot of hateful reviews on here, blaming the company for everything. To begin with, you guys ARE aware that this IS a poison. That's why it kills fleas. I wish I didn't have to use any at all because I don't care for toxic chemicals in general but considering the alternative, you do what you gotta do. Of course there are going to be side effects in a number of patients because it's a POISON. That is why there warning labels and precisely measured doses. They even err on the side of less, just to be safe. For the record, I don't work for the company or anything but people, get some perspective!! Personally I am grateful that I can purchase this over the counter for such a cheap price.

I am so upset I didn’t read these reviews before treating my cat with this horrible chemical. My cat became sick and wouldn’t eat for 2 days, I had to go out of town and when I came back her fur was burnt off of the areas I treated. She has scabs and burns from the medicine. Even though it’s been 5 days since I used this crap, I am going to take her a full bath and get her into the vet ASAP. Such a tragedy this product is available to the public. I’m also worried about what I have been exposed to because I applied it with my bare hands. Disgusting this brand is still in business after these stories.

Do not use this Ultra flea and tick on any pets!!! My two precious cats I used it on one losing hair and my baby had such a terrible reaction. I washed it off with Dawn dish detergent and I still have cats. THIS STUFF IS NO GOOD FOR ANY ANIMAL. THEY NEED TO HAVE A CLASS ACTION LAWSUIT AGAINST THE COMPANY. Anyone who wishes to participate in this lawsuit please email **. Let’s take this company out of the market of killing our pets.

I used the Hartz flea shampoo on my lit. girl service dog and the next day she became paralyzed in back legs. She won't eat drink or anything. Took her to vet. They wanted more money than I had so we had to take my baby home to die because of a flea shampoo. Trying to explain this to my 6 yr little girl was so hard. All my little girl keeps doing is praying for her. Please people don't use this shampoo.

My 13 year old loves to go outside and became infested with fleas. I purchased Hartz cat flea drops for adult cats and applied between shoulder blades. For about a week my cat had decreased appetite. Unfortunately my street experienced a tornado that did a lot of damage and I did not wash it off my cat for several days. A week later and my cat is having labored breathing and will not eat or drink. The vet gave him shots and IV fluids but said it will have to wear off now and he may not make it. I am so upset that this could happen to my pet. Please do not buy this product. I never will again!

About 4 days ago I applied Hartz flea powder for cats and kittens to my 5 year old Cat Stephanie... She began losing weight rapidly and had a ton more fleas and she was an indoor cat... it was almost as if the powder attracted more fleas! She had labored breathing and stopped eating and drinking, she could not walk or move in her last 3 days on earth. She was healthy as a horse prior to powder being applied and then boom last night March 20, 2018 she passed on to the rainbow bridge! For the sake of your pets do not buy this horrid product I have been in shock and disbelief. I feel horribly guilty as I put the powder on her. Please don’t buy this product!!!

I bought Hartz flea drops & used it on 2 of my cats. Within a week they both started to lose their fur. Then within 2 weeks my one cat started to lose weight. Yesterday when I woke up - my dear sweet girl had died. This product NEEDS to be taken off of the market. It kills cats. I wonder how many other cats have died from it being put on them.

My cat just had the worst reaction to the flea treatment!! I wish I read these reviews before using this poison! As soon as I applied it he ran so fast completely out of control. I panicked, grabbed a wet cloth and immediately wiped off what I could and while I was cleaning him with water (which cats don’t like) he started purring...thank goodness! I just made him an appointment with the vet and all I can say is he better be ok! To all my other furry friend parents do not use this product. When I called the vet they told me to come in today and that they have seen Hartz kill animals.

I bought the Sergeant's liquid flea medicine for my cat back in November & never noticed a problem. However when I applied it to my cat, between his shoulder blades, he ran after just getting a couple drops on him. I got him & applied the rest but had to really hold him down. I thought it was because he smelled it before I put it on him. He ran away from me again & once he calmed down just a little I noticed he wouldn't sit still no more than a few seconds. I thought it was because he could still smell the medicine. I was told by a Facebook cat group not to use the cheap store brand stuff because it has killed cats. I got a washcloth & put my Dove body wash on it & washed off what I could of it, he laid there like it felt so good me washing it off.

I treated my dog Roxi with Hartz Ultra Guard Dual Action. After treatment she did begin acting differently. After a couple of days from the time of the treatment, I noticed breathing problems, not eating or going poop, lumps swelling more each day and lumps multiplied. She is on her second day of antibiotics and pain meds. And a good bath to get that crap off her. I will report back in a couple of days to let you know how my poor baby is doing. Added pictures of non irritated portion of skin vs red irritation and lumps and the product.

Tonight I will be putting my male cat to sleep. 2 1/2 months ago I used this product on my cats. We have 3 girls and a boy cat. My boy cat changed his personality and eating habits. After about a month he stopped eating most of his fav treats. He started losing weight. Now he won't even eat. He can barely walk or meow. He is a Himalayan so he is very furry. He doesn't like to be held so when I had to pick him up to carry him up to bed because he couldn't climb the steps. I burst out crying. He is so bony. He does this little sound that makes me think he is in pain. I so despise Hartz. How can they sell something knowing they cause so many animals pain? Merry Christmas Hartz! Thanks for harming my cat???

I used this product on my dogs. One of my dogs started having major problems. Her back legs became very stiff and she became very weak and was unable to go up or down the stairs. After $500.00 dollars of veterinary charges we found out using Hartz products was not recommended. We were told to wash our dogs with Dawn to absorb the oily Hartz Dual Action and then wash with their normal shampoo. I threw out all my Hartz products and my dog is back to playing with my other dog and is able to go up and down the stairs. These products are harming our pets.

How they are still in business is beyond me. A few years ago, I lost my healthy 16 year old cat due to renal failure. It all went downhill for her after I tried this product. A friend brought fleas in my home, she got them bad, I tried this and shortly after, all the problems occurred. Don't use this product.

DO NOT USE Ultra Guard Pro for cats. Instantly, my cat began running and hissing, making a distressed sound, and panting uncontrollably. I called Hartz. They agreed she was having a negative reaction. Suggested we wait until she calms down then to give her a bath or wash the area. I thought she was going to die. I did wash the area as soon as she calmed down which was a few hours. She seems better this morning. PLEASE DO NOT USE ON YOUR PETS!!!

I bought three collars for dogs and two for cats. They worked for the first three days and now the fleas are right under the collars. DO NOT WASTE YOUR MONEY ON THESE PRODUCTS. It seems this is just like everything you buy these days. Everything is as con and a joke.

Hartz flea drops doesn't work. Cats still had fleas and bald. Didn't do nothing for the fleas and also making all 3 of my cats go bald. Y'all shouldn't sell crap and steal folks' money when they trying to take care of our fur babies. All the products should be pulled off the shelfs!

I used Hartz UltraGuard Rid flea and tick shampoo on my puppy and two days later her back legs were stiff and could not walk and would not eat or drink. I didn't understand what happened to her so I called a vet and after $200 of x-rays and test the vet did not know what was wrong with her. Put her on anti-inflammatories and pain meds and now it is a week later and she is no better. I have an a appointment for a second opinion at another vet but after I came across reading some of these other reviews my puppy's symptoms are exactly the same as another consumer.

I recently applied the Hartz flea treatment to my 5-month old cat. Not even a week later my cat starting vomiting, two days after got lethargic and in tremendous pain and died. He died in my arms a painful death. Had a moment of convulsions. I will never recommend this product to anyone! My heart is broken Hartz! I wish I would have done my research.

Let me tell you about Hartz Ultraguard! We put it on our baby girl to help with fleas but take my advice. Do not use anything by them. My husband put it down her back and the next morning she was so sick!!! She had it coming out both ends!! I came home and she started throwing up and with diarrhea and I got to thinking about it and throw her in the bathtub and started scrubbing her trying to get it off of her. She was miserable poor thing. She wouldn't play, eat, drink, nothing. Later on I got to researching and they have lawsuits against them!!! And take it from me it did not work. She had more fleas after using it than before!!! Thank God our baby is ok. It could have been worser!!

Because of this product my cat was vomiting for weeks stopped eating and had to stay in the vet's hospital for 2 days. It cost us $500 to save my fur baby and he's still not the same a week after coming home from the vet. If I could afford a lawyer I'd be suing this company for every penny they have. You’re a horrible company and I feel sorry for your unsuspecting customers who don't know what they're getting themselves into. My cat could've died due to liver damage thanks to your product.

I bought this product a few weeks ago for my kitty who was struggling with fleas. I had read some reviews saying their cat reacted badly to it while some others said it worked fine, so I went with the benefit of the doubt that my kitty would be fine, but I was wrong. Minutes after I applied the medicine she started trying to lick and rub it off, also acting very timid and trying to avoid me. I read these signs very quickly and heard they meant no good for my cat so I quickly brought her to the bath and washed the medicine off with kitty shampoo, and afterwards she was totally fine.

I treated my cat on Tuesday night. Wed morning I found him in my laundry room having a seizure. I rushed him to Animal ER. When asked had I treated him I said yes with Hartz product for cat. Then I learned the product is poison. OMG. If you people have kids remember karma. Get this off the shelves. You know Pyrethrin and Pyrethroids are poisonous so why, why, why!!! My cat is home. I'm feeding him every 2 hrs a liquid diet. He's blind now and weak and I pray for you people my cat makes it because this cat is all I have. He dies I will die with him then hope you all can sleep. Shame on you people.

So this past weekend I noticed my cat had some discomfort and itching. I checked him out and found some fleas. Took a drive to Walmart and got some Sergeant's Flea shampoo, some Hartz flea powder and a Hartz flea collar. Back at home I washed my cat dried him then I applied the Hartz powder. 15 mins went by I went down my stairs and I felt a little funny, went to my kitchen started taking the collar out of its packing sitting on a stool. I lost my balance. My heart was racing and I couldn't focus on anything. My vision was blurred. My mind was racing. My heart was pounding. I didn't understand what was happening.

I wish I would have known about this product before-hand. I would have NEVER have bought it or used it. It caused renal failure in my otherwise healthy five year-old female cat, Sugar. She went from a healthy weight to nothing but skin and bones in less than a week. She stopped eating, stopped drinking, and would rarely move on her own. She finally died, in my arms, tonight, not more than 90 minutes ago. I am beyond furious and heartbroken. WHY IS THIS PRODUCT STILL ALLOWED TO BE SOLD?!

I bought the cat Hartz Ultra Guard Plus. Put it on my cat as parents used Hartz products for our dog back in the 1950-60's. This product made my cat sick. She would not eat. Just drank lots of water. I am an old man 71 years old. My gentle loving female cat 3 years old suffered and died because of Hartz poison. Why are they allowed to continue to make it. And sell it. My cat was never sick a day in her life until I put these drops on her neck. Now she is dead. Buried her this morning.

Hartz flea medicine - This stuff is abrasive and dangerous for your pet. Had a bottle spill in a container and got on a electronic cigarette lighter made of a rubberized coating and the medicine ate away at the rubber on it... I strongly do not recommend using this product ever.

Today on 8/24/2017, I lost my sweet cat of 9 years. I bought both of these products and used them as directed on my cat. She ran after I only got 2 sprays on her back, but she let me put the flea collar on. This was a mere 2 weeks ago. Soon after, she started acting different, not as active as usual, and stayed in the same place on my chair for days... It took me a week to notice her food wasn't being eaten... And she wasn't acting normal. I thought maybe it was stress, or the storms we had been having. Until a few days ago, I picked her up and could feel her spine. I hugged her and loved on her, but she didn't act right. Then she hid for a few days, and I found her hiding spot last night... Well... She was skin and bones!

We just got a dog and it brought fleas in the house and gave my 3 house cats fleas. Even though the dog used this product beforehand. Gave it to the cats, same as everyone else. It made them drool, walk funny and in a daze for a couple of days. We have more fleas in the whole house. Do yourself and your pets a favor buy the ones that cost more because I'm spending more money on getting rid of them from here. Hartz, you suck!

Like many on here I'm kicking myself for not checking this product out before using it. My vet recommended it so I didn't think twice. It's now 11 pm and I'm at the emergency vet with my 1 year old cat. I applied the preventative according to directions and my cat immediately began running around and became extremely agitated. When I managed to catch her about 2 hours later her skin was red and bleeding at the application site and she started having diarrhea.

Applied Hartz flea medicine on my 20lb dog. Read the directions and applied starting between the shoulder blades and worked my way down. The next day my dog would not eat or drink. He scratched a lot and his eyes got a glaze look to them. He looked dazed and confused. We let him out to use the restroom and when he came back in he started walking like he had mad cow disease. He was trying to walk but it’s like his limbs weren't doing what they were supposed to. He tried like 6 times then kept falling. His legs got stiff and wouldn't bend.

I put the Hartz flea and tick drops on the back of my 13 year old cat. It burned his skin so badly he was bleeding. He then began to have labored breathing which continued even after I washed it off. I took him to the vet and his lungs had filled up with fluid and he couldn't breath. They tried to get the fluid out but it at the vet but they couldn't get it all out. I then rushed him to the Penn Veterinary center where he was put on oxygen and medication but he did not make it through the night. Hartz Killed my beloved cat. Never buy this product. There should be a lawsuit.

I put the stuff on my 18 week old kitten and she immediately started acting erratic. She started panting and jumping around and later started drooling. I took her to the emergency vet where I spent 10:30 p.m. to 5 in the morning and dinner having to leave her another day. I know that if I had not taken her that she would not have lasted that evening. It cost me $700 in vet bills. These people need a class action suit against them. I am so surprised that with all of these complaints nobody has insisted that they take this crap off the market. I am more than Furious.

Your product killed my dog. I put the powder on him and rubbed it in like it says and he got sick not a day later. He was sick for a couple of days then he died on July 7, 2017. He was fine, energetic and healthy before I used this product. Now he is gone. I lost my baby boy because of this product??? I just wanted to warn anyone planning to use this not to do it. It's too late for me. I will never see my precious dog again but you can keep yours safe not using this product.

Do not use this horrible product on any of your animals. I placed this product on my three cats and within seconds they began to howl in agony. My one cat Leo howled as he peed on the floor. They began to twitch violently and pant like crazy. I had to detox them with milk thistle. They are still experiencing horrible side effects. My daughter has panic and anxiety and having to watch all three cats suffer like this has caused her and I emotional damage. Please I beg of all of you do not use any of the Hartz products on your pets. We need to band together to file a lawsuit somehow against this vile company that is making animals violently ill and in worse cases killing them. This company should be ashamed of themselves. Even after washing the Hartz Guard Ultra Plus off my cats and detoxing them they are still sick. Please help us put an end to this company now before more pets die horribly.

I purchased the Hartz flea and tick medicine for my cats. I applied it Thursday evening, I got up Friday and went to work early, came home around 430pm Fri... My Buddy Cat, was meowing and on the floor in his spot where he lays down. He was lethargic and not standing up. I knew the medicine must have poisoned him because he was fine and healthy the day before. I rushed him to the bathroom and washed off the back of his neck where the medicine had been applied with blue Dawn dish soap... I then called my friends for the number of the vet. I called the vet and the girl at the desk said to bring him right in. They put a catheter IV in, and administered ** and IV solution. I arrived the next morning to pick Buddy up. He was a little worse. I laid him on my chest from 930am Sat until he passed in my arms at 253pm Sat...

I purchased this product today at Walmart and put it on my cat. Immediately she started meowing and running around the house like she was hurting. We finally caught her and managed to wipe the medicine off, using damp paper towels and even a little Dawn on a paper towel. She appears to have settled down. Sure hope it doesn't kill her. They should have taken this product off the shelves.

I wish I had never bought this trash. I bought and applied it yesterday to my perfectly healthy 1 year old cat. Today she is sick. I am PRAYING that she doesn't get worse after reading other reviews about this garbage. I should have known better than to buy this; I always say you get what you pay for. This crap is nothing but poison disguised as a helpful product. If you are reading this I beg you DO NOT BUY THIS PRODUCT.

I had purchased Hartz Ultraguard Pro for my grandmother's cats. Immediately after application one cat, Ginger started blinking his eyes and you could see the tears running out of his eyes. So obviously it burns. The littler and younger cat, Kitten started salivating terribly. Both of them are miserable. I read on here to wash with Dawn and push fluids. Ginger is not eating a few treats and drinking water. Kitten, however isn't moving much. Every time you get close she growls. However, on both of them when washing their necks with a cool rag with Dawn they seemed to love it. They didn't fight back which is unusual.

My daughter in law purchased this product at a local Walmart. She put it on her cat's neck as described. A few days later the hair where she put the drops fell out. Then the cat began acting abnormally. She finally had to take him to a vet. The vet said the cat had been poisoned by this product. Two days later she brought him back to the vet and was told the cat will not survive and had to put him down. How can this product still be sold with all the complaints being brought forward? I will be going to this Walmart to give them a piece of my mind.

If I could give zero stars I would. I am beyond mad with Hartz. I have used this product before so I thought nothing of it. My dog had fleas so I ran out and picked up some Hartz flea and tick topical drops for puppies. The day I applied the drops she turned red. Again I didn't think much of it until the next morning when my baby was covered in nasty red bumps from nose to tail. I decided to call their customer care line to see what they would say. The lady I spoke with told me it was NOT their product that did it, that my dog already had the issues before I put their drops on her. I know for sure there was nothing wrong with my dog before the drops were applied. Needless to say if you are new or even older pet parent I would stay as far away from these products.

Bought Hartz Flea medicine for cats (which the internet said was safe for my house rabbit). After putting it on her back 2 days later she stopped eating, drinking and when she went to use her litter box there was blood in her urine. To say the least I rushed her to the vet and found out that it was the Hartz Flea Drops that poisoned her. The vet told me not to use it anymore not even on my dogs. So now we are using Advantage. Cost more but cost less than a vet bill. I don't understand how they can still sell the stuff if it does your animals so bad. Should be taken off the shelves.

Wish I would have read these reviews before buying... I have a large black cat and a smaller orange tabby female.... Luckily I actually spilled some before putting on my female but she still ended up with a small burn between her shoulder blades - my black male had no issues... After reading all of the comments WHY is this still being sold. NEVER again... Only reason I used it was because I moved to a new place and they have been scratching - and I found a tick in the apartment...

I purchased and bathed my dog with your Hartz UltraGuard Pro. After her bath her eyes had a green discharge and when I looked at her eyes they looked glazed over. I rushed her to the veterinarian and he said it was the shampoo. My dog is a 23 pound shih tzu. He prescribed eyedrops and pain medication. Her eyes looked glazed over and it seems to have a problem seeing. It is hard to give her drops because she is in pain. I am very concerned she is going to lose her sight.

We sprayed our male cat three days ago. Within two minutes he was uncontrollably scratching and knocking things over. This let up a bit and he went outside. He then eventually became lethargic and just sat under a tree for a long time. When he finally tried to walk it was like his back end was hard to manage. We brought him into the house and from then on he became worse and couldn't move. Our daughter went online to read about the spray used. She immediately bathed Chippey to get it off. He yowled in pain.

April 22nd I picked up my 6 1/2 week bichon puppy. On April 28th at 9:30 we watched him take his last breath. 1 day after picking him up, we noticed fleas on him. After giving him a bath in Dawn detergent, we decided to go to Walmart and get a flea collar. 2 days later he was very lethargic, vomiting, staring off in space, not eating & scratching. We immediately took him to 24 hour emergency. When we walked through the door and told the nurse his symptoms, she instantly instructed me to remove the collar. She take courage in the back to get vitals. After giving him anti nausea med and fluids, 4 1/2 hours and $160 later we were sent home. Two days later back to emergency room with worsen symptoms. It was recommended to have him hospitalized ($784.00 for one night) because the toxins from the flea collar had started to shut down his organs.

I have used this Ultra Guard Flea and Tick for cats in the past. I figured this time it would be okay. I was wrong!! Applied to my 3 cats and within 48 hours my 10-year-old Siamese had to be put to sleep due to suffering caused an from their product! I received a letter today stating that it wasn't the cat formula that would cause this but a topical dog preventive. They have all my packaging including from my dogs!! There is no way my cat got in contact with the dog formula! All I asked for was them to cover my vet bill and they are denying my claim by saying it was from another product for dogs. I would like all of us who have experienced this to please somehow band together and let's not allow them to get away with this!! PLEASE LET'S ALL FILE SOMETHING AGAINST THEM!! TOO MANY OF US HAVE LOST OUR BELOVED PETS DUE TO THEIR PRODUCT!!

This bothered my cat to the point where she was running around, terrified. Also it got in our eyes because of her being around and my eyes started to have a burning feeling. My cat still doesn't seem normal after a few hours of putting on the product. DON'T USE.

I put this product ULTRA GUARD PRO on both my 2 yr old cats 3 days ago and right away they started running around and scratching their hair at the back of the skull/bottom of neck where I put the drops as told by directions. The smell was so bad from drops I had to open my windows. Now my one cat has been throwing up since yesterday, laying around not eating or drinking. I'm trying to keep fluids in her so she doesn't die! I bought this product from Wal-Mart and I still have my receipt and if my cat dies or I have to take her to the vet I will be sue Hartz! Take Off Shelf!! Is this from China!!!

Ok are the fleas here in Texas different than any other state 'cause these ultraguard flea & tick shampoo and spray did not work at all. Was still having live fleas on my fur babies and still scratching. Big failure. Not good at all. A waste of a lot of money. Crap not cheap.

DANGEROUS! POISON! Worst product in stores! Please do not put this on your animal! I have 5 cats; one of which is an indoor/outdoor cat. She has been on Revolution (a prescription flea med) for 5 months since she came to us as a stray, mainly because she had ear mites too. Our vet recommended keeping her on this if she would continue going outside.

This stuff is POISON and it killed my baby!! I bought this product 2 months ago for our beloved kitty Dip. He was 12 lbs and fine. He had FIV but was in good health and had no problems. Happy, fat, and enjoying a quality of life any pet parent could wish for their fur baby! Within a day he started losing fur around the application site. He then developed sores that were chemical burns. The sores and hair loss spread and he lost weight rapidly. We spent over $500 desperately trying to save him. Today the vet told us his anemia was worse and his organs were shutting down. He was 8 lbs. She said that his condition would continue to deteriorate and he would suffer. We made the heartbreaking decision to allow him to fall asleep in my arms one last time with him purring.

I have a cat and so my hubby and I bought the drops and the collar and it didn't do any good. We gave him a bath and followed the instructions and the next day bam fleas, looked worse than before...The product sucks. I would not buy that garbage again...

So I recently got a kitten that had been outdoors previously. So I bathed her and put this collar on her and I noticed large irritation spots on her neck, and she kept scratching at them. I took it off and looked up side effects of this product. I wish I would have saved the box. Will never use again.

My cat, Ginger, got out of the house. When she came back, she has fleas. I bought Hartz flea drops for cats. Didn't effect the fleas at all. My daughter bought a Hartz Ultra Guard Plus for fleas on cats. Nothing. Fleas thrived. I bought another flea collar thinking maybe the first was old. My cat still has fleas. I complained to Hartz and was told about the flea cycle. Bah! I told them and I tell anyone thinking about buying Hartz, DON'T. Complete waste of money. Bath your cat with Dawn. Much better treatment.

I wish it was possible to give a product zero stars because this product is absolutely terrible. I usually get my 3 cats flea and tick treatment from the vet, but I ran out and panicked when I saw a flea on one of them. Anyway, I knew something wasn't right almost immediately because the smell was way too strong. Then I could tell my sweet babies were not okay. I really think it was burning them. Anyway I rushed to wash it off of them and they seem to be doing fine now. But never again! HEY ANIMAL LOVERS, PLEASE DO NOT BUY THIS PRODUCT!!!

I used Hartz tick and flea drop on my 4 year old cat. She immediately started acting strange. She began to pant heavily and her breathing was labored. She was agitated and hissing and then ran under our bed and wouldn't come out. I called my vet and she told me to wash the product off as much as possible with Dawn dish detergent. When she finally came out I washed as much off as possible but unfortunately I don't know how much seeped into the skin. Vet says to carefully watch her and if breathing gets worse get her to the emergency room. Praying that she is ok and hoping no long term neurological problems. I strongly urge you not to use this product.

I put this Hartz ultraguard plus cat collar on both by 6 month old kittens. My boy kitten seemed okay but my girl kitten was going crazy itching her self and biting her self all over. I checked for fleas thinking she was getting bit up but she did not have any fleas on her (Dawn dish soap kills fleas instantly). I got the collars to prevent reoccurrence in case there were any fleas in my house. I looked up the reviews and realized how terrible this product was so took them off both cats right away. It has only been one day but she seems a little better but not by too much as of yet.

Hartz Flea and Tic was applied on this cat which caused severe burns. NEVER use this horrible product. Its use should be banned. This cat was one of the lucky ones. He survived and without neurological damage.

I wish I would have read all of these reviews prior to buying this horrible, horrible product. I put this CRAP on my 9-year-old cat on Friday November 11th. My cat sleeps with me every single night; that night he did not. The following morning, I woke-up because I heard him making very odd breathing noises; he was having a seizure and a hard time breathing. I immediately bathed him to get these toxins off of his body but it had already gone through his skin.

I used Hartz Ultraguard flea and tick shampoo on my 2-year old European boxer. He is now broke out all over his body and can nearly keep his eye open. I recommend that you never use this. It is animal cruelty and this business should be shut down or stop making stuff like this!

Please, do not use this product on your pet. I have just come from my vet's. Last evening Hartz UltraGuard plus spray was applied to our dog, as directed. This morning, upon awaking, I heard our dog vomiting. I ran to his room, and, found large amounts of vomit all over his floor. He was also, drooling badly. The vomiting ceased in about an hour, it was followed by more drooling and clear fluid, followed by more and more drooling and dry heaves. This drooling was only a precursor to seizures, which, surely would have occurred had I not gotten him to his vets. His vet has seen many cases such as this, from this product being reported to her, as being used on their animals.

I had no ideal that a product that has been around for many years such as this one is still in business. With all the laws out there for animal cruelty and abuse how can this corporation be in operation. We bought this product to treat fleas on our 16 year old male cat and after applying according to the directions on the package, we now have a cat without the use of his hind legs. We put baking soda to absorb the oily substance off his fur and skin and gave him a nice warm bath with dish soap to help remove the poison. Hopefully in the morning he will be much better. If not I want to know what steps can be taken to shut this business down? Very upset consumer in Richardson, TX.

My dog recently got fleas and I decided to get the hartz shampoo, flea collar, and flea drops. A few hours after my dog started to lay around, not eat or drink. So the next day she stopped responding to her name and still was laying around. Barely walking or moving so I took her to vet. The vet said that this product was not great and to wash it all off with dawn soap. So I did washed. My dog started to drink some but was still not keeping nothing down and so today I checked on her while she was sleep with my son. And at 713 am I get a call that she was having a seizure and then stopped breathing. Hartz killed my shih tzu... my sasha, my baby!

I have 6 indoor cats, of which one goes in and out. On 2 Oct 2016 I put Hartz flea drops on all of them I had bought. Plus that same week I bought (4) Hartz UltraGuard Plus flea collars and (2) Hartz UltraGuard flea collars all that was on the shelf at Walmart. I am very disappointed after spending over $26.76 on the collars not to mention the flea drops. My cats still have some fleas on them. I don't have fleas in my home just the cats. As I said they don't go out except for 1 and I have been keeping him in after I applied drops and collars. This is very frustrating not to mention the money I have spent for the stuff not to do any good.

These people are cruel animal killers!!! I purchased Hartz Ultra Guard for my daughter's 4 month old kitten. He is now bleeding from skin, and swaying back and forth. You people are sick just trying to make a dollar. We will open lawsuit.

REVIEW OF HARTZ MOUNTAIN FLEA & TICK SPRAY - I had a Persian cat which had fleas. I spray my cat and gave her one tablet of dog & cat quick tabs. She went to sleep in a closet without a door. I found her dead when I got up about three hours later.

I sprayed my 4 year old yorkie chihuahua and my 5 year old Jack Russell lightly with Hartz Ultra Guard. Approx 7 hours later my chihuahua broke out in rashes and was scratching intently. Approx 18-22 hours later both dogs vomiting. Today approx a day later my jack Russell had a seizure. Short but still could have killed him! These are indoor dogs that only go outside to poop and pee! Unbelievable and I know we are not only ones to watch this destroy our animals!

I used Hartz UltraGuard Flea and Tick ointment on my 5 year old cat. Everything seemed okay. No reactions until about 3 weeks later. I noticed a large white scab at the application site. It started to brush off, but mainly stayed on for another week or so. The scab disappeared and now my cat is losing his fur at the application site. There's a small bald patch and it looks like new fur is starting to grow. I will not be using the other 2 applications.

I put the drops on my cat just as the directions said. Within 20 seconds my cat started to gasped for breath and acting like she was having seizures, and the smell of the drops were so strong you could smell it in the whole house. I grab up my cat and started washing it off her. There was no way of getting it off her. I just started blowing in her face and putting cold water on her then she started having diarrhea. She is doing ok now but getting that off her took at least 3 shampoos and still it has been a week and the smell is still there.

About 36 hours after applying Hartz UltraGuard Topical Flea and Tick prevention to my pug, he had a grand mal seizure, his first ever. 22 hours later, a 2nd one. Now, we're just waiting and watching. His vet said that when he worked in an ER he saw many adverse reactions to Hartz Flea and Tick products. The consumer line "medical department" for Hartz (actually, a 3rd-party veterinarian contractor answering the phones) suggested we bathe him with dishwashing detergent, which has been done. But the woman there refused to provide any information on the number or nature of adverse reactions to this product. The Internet is littered with adverse reaction anecdotes on Hartz flea and tick products. I shall do my best to spread the word: Hartz = poison, and not just to fleas and ticks.

I've used Hartz Ultra Guard on my dog after returning from holidays where tics and fleas are rampant with great success. We were in Waterton Lakes National Park Canada where Bison, bears, elk and deer are everywhere and unfortunately, my dog did get fleas while rolling around in the scrub and sagebrush. This product worked immediately on his itchy infested skin with absolutely no adverse side effects. I have read many negative reports on this product and was quite apprehensive about applying it on my boy, but his great discomfort and several sleepless nights was the deciding factor. Almost immediately, his scratching stopped and was asleep at my feet within five minutes. I would use this product again and would most definitely recommend it to my friends with large dog breeds.

On Friday, Sept, 2, 2016, I treated my Boxer/mix for fleas with Hartz Ultra Guard flea & tick prevention for dogs & puppies (use only on dogs and puppies 12 weeks and older weighing 1 to 150 lbs.) I followed directions to the letter. Saturday, the 3rd, she was ok. Sunday, the 4th, she only ate 1/2 her normal food. Monday, she did not eat at all. Tuesday, the 6th, she was paralyzed in her hind quarters. I used the medication as directed, applying between shoulder blades. down her back to the base of her tail.

I put this on my cat and my cat got very sick and now has a big sore on his neck. It looks like a burn. I will never buy this again. I am writing this to let everyone know this med is very bad for your pets!!!

I put Hartz flea and tick drops for small dogs on my 3-year-old dog. I followed the directions on the package and applied accordingly. Her hair from her neck all the way down her spine to her tail started falling out, and burn marks appeared. I gave her a bath but the damage was already done. Now her hair is falling out on her sides and underbelly. DO NOT put this product on any of your animals!! Plus the company doesn't care at all.

Our poor baby, Julio, a 55-pound boxer-lab mix has been itching like crazy! The fleas seem very bad this year. We have tried numerous remedies, spent lots of money on products that do not work. I picked up a Hartz ultra guard flea & tick collar at our local grocery outlet for $3.96. Put it on last night. This morning, no itching!!! It's a miracle! It smells good, easy to put on, it actually works. Who knew? I highly recommend this product and if Julio could talk, he would too! Thanks, Hartz. They ought to call this Hartz doggie butt saver 'cause he doesn't bit his poor butt anymore, either lol.

On 8/26/16 gave one dose as directed on 8 year old female feline named Clover. Following morning Clover awoke drooling, no appetite for 24 hours, slept entire day in a few different places - this morning on 8/28 she was back to her perky self with appetite and activity. I will pursue returning for credit to Hartz and/or discard this product and NEVER USE AGAIN! Will also let our Vet doc know. We are one of the lucky ones!

After reading other reviews I too am so far lucky, we put that poison on our cat and she now has severe chemical burn and fur loss. Will never buy a hartz product again.

Both of my small dogs had reactions the next day to the use of the flea and tick ampules that are applied from the shoulders down. They both had RED eyes, the smaller of the two could not open her eye and was lethargic. I saved all the vet bills which amounted to about 700 dollars. I was not expecting full compensation but I would expect a large company to be a bit more compassionate.

You think when you go to the store and you purchase a product from a company that's been around for years that it is perfectly safe for your animals. I am really pissed off right now. I just put this product on my adult female cat and immediately she started convulsing and foaming at the mouth and getting sick and started running around and hiding and crying in pain. I wish I would have read these reviews first before I applied it and I pray to God that I haven't killed my cat. I was going to apply it on two of her kittens that are 12 weeks old but she had this immediate reaction. I've done the best I can to wash it off in warm water and Dawn and I pray that I got most of it off.

I purchased at Walmart on Aug 6, 2016 and when I got home applied to my 9-year-old cat. The next morning 01:30 am I awoke to her having a grand mal seizure. I took to vet 7 am with her stitching and drooling. The vet gave her ** to calm her. This did not work and then they gave my cat ** to no avail. They had to put the cat down. I do not want any money back but for the love take this off the market... It is too late for my cat but it may save others.

My cats needed a flea treatment due to a kitten we had adopted a few months back that had fleas. So my boyfriend bought this product at Wal-Mart mostly due to the cheap price. HA well there's a good reason it's so much cheaper than all the other brands. 10:30 am I applied this Hartz product to two of my cats. My oldest 9 yr. old male cat, and my 1 year old female cat. 10:45 am by this time, Stevie (female) is howling in agony, running around, hissing, and panting like a dog. She is flying through the house and she can't sit still and when she does she's trying to roll on her back. I'm guessing to rub this poison off.

When I applied this ointment to my 5 year old male cat he was running around meowing like he was in extreme pain, within a day he has been scratching violently and losing hair at the site of application. My cat has become very paranoid of everything including me. I had 2 doses left, these were immediately thrown in the trash. Some of the reviews I read, I consider my cat lucky by not having some of the more major problems other pets have had. The reason for this review is so other pets will not be exposed to this lethal flea ointment. Please Hartz Mountain, take this dangerous stuff off your shelves and see what the problem is.

To all pet owner's and veterinarian's: On Mon., Jul 18, I applied Hartz Tick & Flea oil on the back of my dog per directions. A few hours passed and all of sudden my dog could not walk. Took him to the vet. Did blood work and urine. Blood work came in as very high diabetes and blood in the urine. So the veterinarian said "Bring him in the next morning and we will check the blood work again." This time it was normal. So the veterinarian concluded that it was from the Tick & Flea application. Today is day 4 and showed a slight improvement, but still falls over and has scratching spells.

WARNING: This product is HORRIBLE! Do NOT put this on your cat!!! My cat started twitching severely, drooling uncontrollably, panting like crazy, was meowing in agony, dry heaving and having seizure-like symptoms. I had to wash it off to give him some relief. I thought he was dying!!! This needs to be recalled and taken off of the shelf immediately!!!

I applied the prevention just like it said to and it did nothing, did not kill the fleas and my dogs are still scratching and biting themselves. I can still see fleas on them. I don't have a lot of money so I got this due to the price hoping it would work. I guess I should save my money to get the more expensive to make sure it works.

This was my second time using this product for my two cats and the same reactions occurred. I was already hesitant to try it again because of the reactions they both had the first time. Immediately after application they darted off and were running frantically. I noticed saliva coming from my cats mouth and she then began to foam out of her mouth. (Same exact reaction the first time) I quickly grabbed dawn soap and water and began to scrub off the medicine the best I could.

I applied to all 3 of my cats (who have had diff types of Hartz in the past), all adults, over 9+ lbs. Within 10 min they were crying in pain and running around the house very agitated. One started drooling and panting. The other just kept running into things. I read these comments and immediately washed all three. They are immediately more relaxed but now almost exhausted, won't stand or sit. Only lie down. Maybe a prev commenter was right that it is dog strength. Maybe it was an error on their end but hasn't been recalled. I purchased from Walmart and will be returning tomorrow. I hope we are truly in the clear and washing did the trick???

Hartz Ultra Guard Pro for cats - We put this stuff on our full grown cat about one year old this morning and went to work. Got back and she is running all over irritated and cannot sit still. She is breathing pretty fast as well. I have seen this before when someone out a dog flea med on a cat by accident and that cat acted the same way. All our vets are closed and we have no emergency clinic near us so we will have to wait and hopefully she will make it through the night. If she dies or I have to pay any vet bills I WILL be getting Morgan & Morgan law firm here in Central Florida to look into getting reimbursed plus pain and suffering.

Ok so I got a new kitten and she is now almost 4 months. So I got flea medicine before she gets them too bad. So I shopped different brands. Well my other cat I had I put Sergeant flea and tick on him and by morning he was lying in the floor in my dinning room seizuring and foaming at the mouth. Well long story short that crap was ** and killed him and this stuff hasn't made her act any different. So I guess we will know in the AM.

Within 15 minutes of application my cat began running and darting around frantically, slight drooling, heavy panting, tongue out and curled, agitated, charged at me like she didn't know me, ran to the litter box and defecated. I called the 800 number on the box and reported the side effects. Washed the area with soap and water as instructed. Offered treats/food. After another 30 minutes she showed some improvement. I am watching her closely. Very scary experience. I thought my cat was going to die. As a precaution I washed it off my other two cats. This should be off the market. I hope there are no long term effects. My cat is hiding under the desk at present.

I applied this product on my 4 year old American pit bull. After I applied the drops, he started running around and scratching himself against the wall. He looked like he was posed. I immediately went online to look at the reviews, and I was faced with endless heartbreaking stories about many dogs and cats dying because of this product. I have him a shower about right after, but it seems like he is still itchy because he's still scratching himself like crazy. I am so scared that he might not make it. This dog means everything to me. I don't understand how this company still sells its products after so many complains. HOW MANY CATS/DOGS have to die before this product is banned from the market?

Terrible!!! Made MORE fleas on BOTH cats!!! Obviously it doesn't work Hartz!!! Or don't you already know that IF you read the reviews? Shame on you!! Not working & some cats DYING!!! Isn't that illegal in America any more, or does ANYTHING GO as long as your company is making millions?? Wake up politicians, this ain't RIGHT, no matter how you cut it!!! Bring Hartz forward to answer charges of "where shall I start?" The list is so long. Hartz, how do you sleep at night? Probably fine, with all that illegal money. You make me SICK. Karma, watch out.

This stuff smells worse than nail polish remover. All three of my cats started having bad reactions to it within 10 minutes of application. They appeared to be anxious, itch and be in discomfort at the site of application. Also, between the shoulder blades/neck or not, my cats are like owls and can turn and lick just about any part of their back, including shoulder blades. I've never been so worried. I will never buy this poison again. I'd rather keep my cats indoors than risk giving them something like this. I washed it right off them as soon as they started reacting badly. I don't know why this poison is even legal for stores to sell.

This poison does terrible things to your cat. I'm surprised with so many complaints, it's still allowed in the market. My cat couldn't sleep, had anxiety, pacing, and hair fell out at the application site. Unfortunately, like most other people, I didn't read the reviews until after she had symptoms. I would definitely not recommend this product.

My poor cat is drooling and sick 4 hours after using this. I didn't know this could possibly kill my cat! I am so worried even though I washed it off his fur this poison is in his system! He likes to go outside and I was only using this keep him free of ticks and flees. It's Thursday 11pm and I have to wait until morning to call his vet.

I put the collar on my 12-year-old terrier/chihuahua cross on Monday to take her for a walk. Tuesday morning, she would not eat or drink and was very lethargic. We took her to the vet at noon and they did a lot of blood work and sent it to the lab. The first thing the vet did was take off the flea and tick collar. By that afternoon, our dog was extremely sick and was vomiting, she couldn't even keep water down. At 3:00 A.M. we were woken up to her crying in pain. She was convulsing, drooling and was having trouble breathing. Her eyes were tearing and glazing over, her legs spastic and then rigid with pain. By 6:30 A.M. she was dead. She died a horrible painful death. The blood tests results came back that she had basically been poisoned. She was in severe pulmonary distress.

I just applied Hartz UltraGuard Pro to Bubbles (our cat). She had an immediate adverse reaction. She started running around panicky and then plopped down on the bed hyperventilating. I feel horrible for putting this poison on my cat. After bathing her to get this junk off my asthma kicked up. I almost vomited. This stuff is horrible. I've never had problems with this stuff before then again the smell has never been this strong. BEWARE OF HARTZ FLEA topical for cats and dogs.

PLEASE DO NOT BUY THIS! A picture is worth a thousand words. See for yourself what happened to my daughters cat after we applied the drops.

My dog was poisoned by this flea collar. They simply don't care. I had a perfectly healthy 14-year old dog on Thanksgiving 2015, and 2 months later my dog is dead. Sent an email to Hartz and they don't even acknowledge the email. FDA approved.

My cat is 10 years old and I gave her these drops as a preventive measure. The next morning when I woke up, the cat had thrown up all over the house. I have tried to wash her with Dawn dish soap but with some cats, that's not the easiest thing to do. We went to the vet yesterday as that was the 5th day that she was still vomiting. The vet had informed us that many cats have died after using this product. There are so many horrible side effects! I'm really upset that I gave this to my cat and I feel it should not be on the shelf!!

WARNING TO CONSUMERS: DO NOT GIVE YOUR DOG "HARTZ CHEW 'N CLEAN". THIS PRODUCT IS VERY DANGEROUS! Hartz "chew 'n clean" needs to be taken off the market. These are not safe. I purchased a large size, for 50+ lbs dogs on Wednesday evening for my 55lb, 2-year-old dog. She only had it for 10-15 mins and had chewed off the end of it. So I took it away from her. Didn't think much of it but was surprised how quickly and easily it came apart. Saturday morning she vomited up yellow stomach acid. Then a few minutes ago (now Sunday morning), she vomited up a clump of blue plastic from your product. This is awful and is going to cost vet bills to have her checked, plus it has made her ill. This is not right and these need to be recalled asap. I will be contacting a law office for advice. This is not okay in any way. This plastic sat in her stomach for over 3 days! DO NOT GIVE THIS PRODUCT TO YOUR PET!!!

This product can kill your pet and cause neurological injury. After I applied it, within seconds, my cat lept off my lap and landed with a wobble. This is weird because she is an apex hunter and always moves with precision. She stared at me blankly for about a whole minute and then turned in another direction and stared for another three minutes motionlessly. Then she darted away from me as if I were a threat to her. When I got her out from underneath the furniture, she was completely flaccid, like a cold noodle. I knew I had to wash it off of her thoroughly. I used dishwashing liquid and some pet shampoo (sentry) and lathered her neck real good. Then I toweled dried her real good. She still looked despondent. I fed her some of her favorite tuna, mostly because I know she loves it and it was my way of expressing apology. She ate it and curled into a furball on a pillow. We'll see tomorrow how she is. I'm so sorry Essie!

I used this medication on my cat on Saturday, November 28th 2015. Followed all of the instructions on the box as I have the last 9 years using other products since I adopted my cat Aurora. She was in perfect health until a couple of hours after I applied this medication. For starters she lost all of her fur at the site of application. Then she started twitching and getting very aggressive. We called a vet friend who immediately knew about this and advised me to bath her with mild soap (We used Dawn dish washing soap as recommended).

I just put the Hartz Flea and Tick on all my animals all 4. Now my one cat is acting real strange. Won't sit still, twitching in her arms. I looked up reviews. After I read them I bathed her hoping it would get it off her. As I sit here and watch her every move my heart skips a beat knowing I may have just killed her. How is this still being sold after so many bad reviews. I have 3 other animals I am now worried sick about. I pray they all come out of this fine. Never again will I use this product again.

I bought this product yesterday, after one use of this product my cat started to develop seizure. Upon my research on this product, found out other people having the same issues put this product. I don't understand why it's on store shelves and it supposed to be recalled.

My 3 dogs have hair loss, red skin, itchy.

Bought 5 boxes, as I have 6 animals all weighing different weights. Used this product and instead of being flea free, fleas had gotten worse. As everyone knows the product is not cheap. I spent right around $80 and nothing! No relief, and fleas!!! My income is on the low side and I demand to be reimbursed. I trusted this product would work and it definitely did not. I should have read up on this product before spending the money, but this is the first time in 5 yrs we were not in the financial means of having a preventive from our vet. Our girls and two boys have never seen a flea. This saddens me terribly.

I am sitting here right now with my dog so sick from this flea drop that I am wondering and praying is my Snow White, five pound Chihuahua going to make it. I bought the drops at the local Walgreens store. Little did I know what I was doing. I put the drop on her last night and within minutes she was acting like a drunk person. She could not get comfortable. It’s been miserable for Her and for me to watch her be so sick. It wasn't until I Googled these flea drops that I saw just how bad this could be. This product should not be sold, its poison. I plan to raise hell with the company tomorrow. Shame on you Hartz. Still don't know if she will make it or not.

I gave my cat Hartz topical flea treatment. Within a few hours she was having seizures, was disoriented and very sick. Nothing like waking your three small children at 11 pm to run your cat the vet. When I talked to the vet he said this is a common reaction to this product. I was appalled to find this out. My cat got IV blood work and the treatment. She had seizures for over 12 hours. I'm pissed the product is even sold and am going to do everything in my power to make sure no one else has to suffer watching their animal that sick.

I have purchased two Hartz UltraGuard flea and tick collars for large dogs and my pet still has hundreds of fleas. This is a 26" collar that I cut to size after a flea bath, and since then have bathed him seven times and applied a new collar with no results. I am going to spray the area where he stays and give him another flea dip and rinse but I am having trouble with this seven month collar. What should I do? Can you help?

We have a pit bull that was healthy until we put the flea drops on him. We couldn't figure out what had happened to him. He started not wanting to eat, walking sideways, lethargic. The only thing he wanted was water. We were trying to figure out what we may have done that was different and my husband remembered the tick drops we bought. I looked up this product and was horrified to see all of the bad reviews and what others said happened to their pets. This product should be removed and something should be done to all of the people who have suffered heartache because of these drops. We have just given him a bath and praying he will start doing better.

I bought this product hoping this over the counter medicine would help my cats from suffering with fleas. Instead they were suffering from this product. Their skin turned red and bumpy. They were crying with pain and discomfort. This product was burning them. I love my cats and to have seen them in this much pain really upset me. I wish the ingredients would get changed so no more animals have to suffer.
