Hartz Mountain Flea & Tick Drops Reviews

We bought Hartz flea and tick tubes to apply to back of the neck and right away "Fergie" (our 1 yr old cat) let out a screeching meow... and ran off. She's been lethargic for 2 days almost 3!! My wife called the vet and before she finished even telling her what was happening, she said, "Omg! Was it Hartz brand?" We said "yes". Vet said they see it a lot and animals die because of it!! Said to stay as far away from Hartz as possible!! Traumatic as hell for all of us and of course Ferg! I'm going to attach a pic if it lets me...

On Monday, August 3, I had to rush my 5 year old cat to the vet due to her distress within fifteen minutes of applying this dangerous product!! She started to pant, tremble, and had the most heart wrenching vocalization of extreme distress. She has Pyrethrin Poisoning, flea and tick pesticide. As of today, Thursday the 6th, she remains in the hospital being treated for tremors and twitching.

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!
