Hartz Mountain Flea & Tick Drops Reviews

If I could leave zero stars, I would! Do NOT, under ANY circumstance, apply these products to your animal! I used a flea collar on my dog and it gave him what looked like large hives and a skin reaction. Almost like it dried his skin out but it hurt for me to pet him. You could see him flinch when my hand touched him. He started having muscle spasms and was very lethargic. So, I removed the collar. But, after a day the "dry skin" just turned red and if I ran my hand up his back instead of down, wherever the hair was disturbed, the skin would bleed. Two days later, the "hives" have turned out to be huge blisters and are busting open when he moves too fast. I don't know how this company is still in business! I don't know how these products are still on the shelf! Protect your pet! Avoid HARTZ brand! The attached picture is the only one he would let me take. He won't let me mess with the sores for more than a second and that's just to get a look at it.

I am a working woman. That it is all I can do to pay the bills these days and that had a healthy beautiful black Bombay cat named Zara. Unfortunately with the way times are I couldn’t afford to go to the vet like I use to and get flea medicine for my precious 3 year old healthy black Bombay girl. So I picked up Hartz flea drops for her. Unfortunately as I was going to bed I and went to the room she was very weak foaming at the mouth and went into a seizure and had several before I could get her to the hospital. Her eyes I couldn’t even see the green beautiful eyes she had. All I could see was black as she was gasping for air and twitching before she repeatedly keep going into a seizure. I wiped her mouth and her arms and paws from where my baby had been having the seizures me not even knowing.

This killed my son's 5-month-old kitten. I don't recommend this product. The company needs to make this product safer for the animals. Please stop buying this product or you will regret it. It is heartbreaking to watch a loved kitten die from this product.

This product killed my cat. I would post a no-star review if I could. Do not use this product. Hartz was subject to a class action lawsuit over the matter, but it was settled out of court. The issue of their products still exists, but it's hard to get corporations to be accountable, especially after legislation passed by the Trump administration in regards to class action lawsuits against corporations. Remember- Hartz kills pets! Please google this subject before buying their product. My Furby lost her life, she suffered horrible symptoms before she died from the pesticides in their product. To make matters worse, when I called the consumer help line for instructions on how to handle my cat getting sick from their product, they insisted that their product couldn't make her sick.

Please please do not use this on your pets. I bought it from Target because I had run out of the one my vet prescribed and this one looked like the same branding. The first red flag was that the dosage seemed much larger than other brands. When I put it on my cat, she hissed and whined as if it hurt which is something she’d never done before. I assumed she was just being dramatic and let her run around for a few minutes. She kept sprinting around and panting whining through the house. She would run and then lay herself out while hyperventilating and whining. She kept scratching at her neck and coughing.

I poisoned my daughter’s cat in 2001 with Hartz’s flea and tick drops. When I posted about event on a blog there was so many people who did the same and lost their cats. We had 3 people that lost theirs and they were white collar crime lawyers. We formed a civil suit and won. Hartz had to take off shelf but in 2 yrs they were back. They changed name and a few ingredients and it was still killing and harming animals. Why they are allowed to sale this product is beyond me! It is heartbreaking to read these reviews. Brings back horrible memories, so sad and frustrating.

Worst mistake to buy this product due to being “cost-effective” My sweet baby girl Venus only 2.5 years old had to be put down (July 11, 2024) due to toxicity from applying this product. We tried to save her $3000 down the drain. My 11-year-old daughter who already had anxiety issues, her best friend is now gone! She can’t sleep properly and cries endlessly. Our hearts are broken.

Hartz® UltraGuard® Dual Action™ Topical Flea and Tick Prevention for Dogs and Puppies 5-14 lbs caused my pup to get sick and have diarrhea everywhere in the house even on my carpet. I am not happy. Soon as we figured it out, I had to wash it off then her stools became solid and normal once again. Very toxic product! I will never use it ever again. I wrote to the company. Will see if I get a response. Wondering if there is any other ways to report about this issue?

For those looking for a cost-effective way to control fleas and ticks, it's a recommended option. My pet did not react negatively to the application, and it was an easy process overall. I soon observed that there were less fleas and ticks than there had been previously. Consult a veterinarian if any issues emerged, even if the product worked successfully for my purposes. As far as keeping my pet safe from fleas and ticks goes, it was a solid investment with good results.

My cat started acting weird a short time after using this medication. Itching and pulling her own hair out. I looked up how to get it off of her. Thank God it was only a few hours. I put some dish soap in the sink and washed the spot off. She's not itching anymore but her back is still twitching a bit. I hope to God I got it in time. She does look to be far more comfortable now. I will be contacting Amazon and telling them that they should remove any product from this company.

This company has to be one of the most irresponsible companies on the planet. Their products are poison and dangerous!! They need to be closed down. Before I knew how toxic their products were I used a flea & tick product (as labeled) and it almost killed my pet. Please don't purchase from this company!!

My family dog is poisoned by HARTZ flea drops. Having seizures, peeing on himself. I'm not sure he will live. All because HARTZ! Review after review and the company knows their product kills. Never buy Hartz.

I had one cat die, a day after using this flea treatment. She literally suffocated. My other cat lost her hair and had a hard bulge on her stomach that burst and exposed her inside. If you ever listened to anyone, please believe me. This product is poison. If I had the money, I would have Hartz in court. I'm certain, this company will go bankrupt someday. Please spend more money on a quality product. I so regret my choice to use Hartz. I love my cats, I can't stress that enough. Hartz flea is not a option. I pray to God whomever continues to produce this product, has what's coming to them. Enjoy your life. Your product kills animals, and you know this. What comes around, goes around. You'll get yours.

I bought Hartz ear mite drops for dogs. And I followed the directions to the T. Within 3 days, my HEALTHY boy, became sick and I took him to the vet on an emergency, which cost us $180.00 for my vet to do a full blood work on him. He had TOXICITY POISONING, and the vet rinsed his ears out as best as she could and gave him some medication to help him. and told us he was doing better, so we got to bring him home. This happened on September 22, 2923. On September 22, 2023, our boy Boston, still wasn't getting any better, he was wobbly, in pain, and wouldn't eat, drank very little water. My husband and I took turns sitting and sleeping on the floor next to Boston, next to our bed, keeping him company and keeping him calm, and giving him water. Needless to say, it was a very long day and night.

I’m pet sitting 2 cats for my son. One male and his female companion both 3 years old. The female is an indoor/outdoor cat. So out of safety concerns our family agreed that both cats should wear flea collars or at least a treatment should be applied. The female cat has on the flea collar and had the same treatment on her neck as the boy cat. She’s fine so far but the boy cat suffered a severe burn on his neck and hair singed Within several hours of the application. He’s extremely attached to his comfort pets and very very upset that these ultraguard products harmed his pets and could’ve killed his 2 cats. THESE PRODUCTS MUST BE BANNED FROM BEING SOLD IN AMERICAN STORES.

An hour before that I called the an ER vet, her response after I told her WHAT BRAND I used was ohhh, and a long pause. Adding, this brand has been KNOWN to kill dogs.

I got these flea drops for my cat and dog based on their weight and had them set aside in case we'd need them. Lately, my dog started itching a lot and biting her thigh. Thinking it was likely to be fleas, I went to get the Hartz Flea Drops and read the instructions thoroughly. Opened the tube, started between the shoulders, dragged down until the tail. There was A LOT of product, half the bottle was left and I have a 110lbs dog - so went for another stripe. Immediately, my dog started acting strange. Circling around and seeming restless. My dog is an old girl, 10 years old, and she's quick to show when something isn't right.

Well like many other reviews I just read my situation is pretty much the same. After using the Hartz ProGuard Flea & Tick treatment my dog within minutes starting acting strange and crying! He even broke my heart whenever he started crying and pawing at me to help him... Being his mama I felt like ** not being able to help my baby boy, well not knowing what to do! Anyways he eventually calmed down a bit but now he doesn't wanna. Get up or do anything and still every couple of hours he'll starting breathing super hard and pawing at me and my skin is also starting to break out from this awful awful Poison drops.. Well now going on day 3 and he's still not himself. I can tell he's hurting cause he doesn't wanna leave my side but definitely dawn dish soap baths are helping (Thank God for Dawn) but I'm worried about irritating his skin do to the dawn baths on top of this torturous application, a dog's skin is sensitive and his skin seems to be fine right now.

Shortly after feeding my cat delectables, ER visit w/ 104.7 & FOUO. Meds didn't work. Next vet w/ 104.3 & after mult tests FOUO. He wasn't eating even after tube, couldn't breathe, temp spiked & died.

You should look at all Hartz products carefully. How can something cost so little that normally cost so much? Questionable ingredients. I bought a pack of flea medicine (drops) for my 2 cats, my one cat was fine, although the fleas persisted, only a few remained. My second cat got very ill for 24 hours after taking the medicine. 3 months later he died of a blood clot. He was 3 years old... Blood clots have to build and don't get clogged in the arteries right away. He was paralyzed in his back legs and there was no vet open that have the equipment to find the clot and fix it, so he was put down. THAT's Hartz medicine.

I only even bought this stuff because is was all I could afford and now I have to come up with $3,000 to pay to get surgery on my cat. I bought a flea collar for her and within weeks she stopped eating or drinking anything, took her to the vet to find out she has Hepatic Lipidosis (liver failure). She is going to need very intensive treatment because of it. This company's product SHOULD NOT be on the shelves at stores. Please do not use on your animals!!

I purchased this collar for my Bearded Collie (45 lbs). Within a week she became lethargic, wouldn't eat or drink and her gums were pale. I took her to my vet who immediately removed the collar and said "it was very dangerous and should not be on the market". She did blood work and kept my dog that day. The next day my dog seemed better so we took her home and each day she improved. The blood work didn't show anything conclusive that would have caused her condition. The vet had not given her any medications so the only variable was the Hartz collar. I wish I had been warned before losing $850.00 on vet bills.

I don't understand how this company is still in business. My cat almost died and spent the night in the hospital. I didn't know all of this until after my vet told me. Right after I put the drops on him he went NUTS. He started having severe spasms, he was TERRIFIED, screaming, crying, sprinting around and hiding. It was the most traumatic experience I've ever seen an animal go through. Thank GOD I brought him to the ER vet (an hour away saturday night) RIGHT AWAY where he was hospitalized for 36 hours. They told me if I waited an hour he would have died. I cannot wrap my head around this. PLEASE spread the word and NEVER use this greedy, sick company's products. My heart goes out to all who lost their pets.

I have two dogs and we have tried out a few different products when it comes to flea and tick. We have never had an issue until we used Hartz. Our experience with Hartz was the absolute worst. We contacted them regarding the fact that since applying their product we had still found multiple ticks attached to our dogs that we needed to pull out of them. One night we ended up taking our dog to the emergency vet because there was a tick burrowed well into him and the entire area was swollen. They removed this tick and found another one burrowed right next to it.

I have a 50lb male All American Pitbull. This was the first time and of time I have ever used this product on him. I urge any person who has experience their pet having an adverse reaction to this medication to report their experience to the EPA as they are the ones who monitor topical flea medications. File your report through the EPA website, which can be found under the pesticide for pets and animals. The more reports they get the more they will investigate this product.

I bought this product earlier this week from Walmart and thought I was simply getting a great deal compared to what the vet offers. I was so wrong! As soon as I applied the drops on my 14-week old kitten, she was very distressed and acting very off. I was going to leave her be but my gut instinct was telling me that there was something wrong with these drops. After a quick search, I found that this kills cats and dogs! For goodness sake, people's adults' cats are dead, what would this do to my kitten?!!! I right away gave her a bath and I am so glad I did that! It's been a week since I applied this, and everyone in the house can still tell that something is still off. It's horrifying to read that people's cats suddenly died 3 months after using this product. To everyone who has applied this product, go give your cat/dog/etc. a bath right away!!!

Just like many other people in these reviews of Hartz, my dog too has been a victim of this "medication". We needed something to help with the flea issues she was having, but didn't have much money, so we thought we could trust Hartz. Before using the product, my youngest dog, who was 5 almost 6 at the time, had a clean bill of health and was not prone to seizures. After application about 3 or so days later, she started to convulse. My mother and I quickly drove her to the vet and after explaining to the vet tech, she told us to not use the product because of the danger it could cause to animals.

I bought my 5 almost 6 month old cat who weighs around 11lbs Hartz flea and tick prevention ultra guard pro because she obviously has some fleas. After putting this product on my cat where directed less than 5 minutes later she started to foam at the mouth and became lethargic!! I called our vet right away and told them what was going on and the product being used. I was told to immediately drive her to an emergency center because the product placed on her is highly toxic!!! After hours at the emergency center and hundreds of dollars later we were finally able to bring her home! I will NEVER use Hartz products again and I will NEVER recommend using anything from them not even food products!! I can not believe that we almost lost our baby girl to some pet medication that we thought we could trust! My kids were devastated and said they will never forget that moment.

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.
