Flea drops

This Hartz junk has been going on for over 30 years. I had gotten some to put on my 3 dogs at the time and not 5 minutes later they all started throwing up. Had to get the people next door help me wash them all down to get it off of them but they still were sick. Hartz was no help at all…I sent them an email about what happened and they said take my dogs to the pound…when I am able to get to a store and see this junk…I want to throw everything off the counters. This stuff is a killer. Anything with Hartz name on it needs to go in the trash. Please don’t buy there chew bones or toys…

Poodle Mix patchy hair loss

I used Hartz Flea Shampoo on my poodle mix now has hair loss and red sores. This product is poison!!!! I’m overwhelmed with guilt that I used this product on my dog.

Bald spots

We have used this on our Pug and he has a bald spot on his side since we have been used it. It just irratted his skin so bad that he scratched the fir off his side.

Scooter the Pug

The beginning of December 2020 I applied the Hartz flea medicine on my senior dog Scooter, a few days later I noticed he wasn’t himself. When I found this post it was too late and he had already passed and the whole time I thought it was just the old age. I’ve noticed the symptoms to be similar like everyone who has posted here.

Stop Hartz from Killing Pets

On January 31st our puppy Jack died about an hour after a bath with Hartz flea shampoo. He was a playful, loving, healthy 9 month old puppy. Jack brought us so much joy and love but due to Hartz poisonous products he wont be here for his 1st birthday. The chemicals in Hartz product caused him to lose his life before we could even get him to the vet. We have created Justice for Jack to spread awareness and help other victims. You can visit our instagram (Justice4Jack) or sign the petition to remove Hartz products from stores.

Fluffanutters the Cat

I used the flea medicine by the brand Hartz on my 7 year old cat, a week later she started to hide around my house and I could smell her Oder. She finally came out of her hiding spot and she looked so ill and skinny and she started meowing non stop, I knew she was passing and she wanted to let me know as well. I spent her last few moments holding her and telling her that I’m sorry.

Delusional puppy

My 4.5 month old puppy had flea problems. I followed the flea and tick treatment as directed for his age and weight. Almost immediately he started to whine. I watched him for 10 minutes and checked his skin, no redness, but he was clearly unhappy. I decided to wash him. As I was getting things ready, not even 2 minutes later, he started losing his balance while walking, played on his side and his eyes rolled back. I freaked out and immediately got him cleaned and awake. Gave him water and food. Right now we are 2 hours later and he is still dizzy but is up and moving around again. I just realized the shampoo is a Hartz product as well so we will be giving him another bath shortly with Dawn Dish soap as recommended by the vet. I’m scared for my puppy… the 24 hour hotline provided on the packaging says no one is in office…


Bought the flea and tick reflective collar made sure they weren’t too tight and about 3 to 4 days later he looks like this but I have a female cat that is fine wearing hers

Chemical burn?

I adopted an 8 year old cat. He has stayed indoors. He just turned 10. One day, he decided to dart out the door. It took a couple minutes but I caught him and took him inside. A couple days later, I noticed fleas. I purchased the Hartz flea collar. The following day, I checked to see if it was working. I noticed his skin was a little red. Thinking it was too tight (even though I could fit 2 fingers under it comfortably), I loosened it. Two days after that, I noticed missing fur and what appears to be a burn. I took it off and got a closer look. It is the beginning of a chemical burn. And some of his fur has fallen out. Never using Hartz again.
