Hartz flea and tick products are commonly known to cause damage to the liver, heart, nerve system, and even death to dogs and cats. These stories are not rare cases and many have been shared on www.hartzvictims.org. The other day I saw a very graphic picture on Facebook of the damage done to a dog by the Hartz flea and tick products. I work at a Petstore and was horrified. I’ve never heard anything like that happening with any other flea and tick products. I am not a victim, nor have I ever used this brand, but have a dog and cat. I can’t imagine what the victims have gone through emotionally. I emailed Hartz and they replied saying that it was either the pet parents fault for misusing the product or an allergic reaction. Which is obviously not true because I’ve never heard anything like happening to any of my customers.

Example stories from the site:
"When our precious kitty “Sparky” was 3 years old, we purchased Hartz Flea & Tick and applied it to the nape of her neck. Within a few minutes she began falling over, not able to stand. To this day, she still wobbles when she stands and walks. I would like to see about filing or joining a lawsuit about this horrible product. Our pets are our babies and it is hard when you know you gave them something that you thought you could trust and would be safe but intead it cripples them." Story shared by Jenny Kearns

"Last night, my parents decided to give our family dog, Teddy Bear, a bath before they left on vacation this weekend. After giving him the bath with Hartz shampoo, he was unable to walk. My mom thought he was just slipping on the tile floor, so she didn’t think a lot of it. He started acting normally, and then they went to bed. Early this morning, my mom woke up to have Teddy acting strangely. He acted distressed, but he’s a funny little guy, so she wasn’t sure if something was actually wrong. Later that morning, Teddy lost his ability to walk completely. My parents immediately rushed him to the vet’s office, and her first response was that it was the Hartz shampoo. Teddy is a 10 pound yorkie-poo, but it still took two valium shots and three baths to keep him from having a seizure. He seems to be better now, but he is still unable to walk and is lethargic. The fact that this website even exists is proof that Hartz needs to be taken off the market. How is it that a company claiming to help animals is actually killing them and getting away with it? I will do everything possible to make sure something is done. I’m very lucky that Teddy Bear is still here, but I never want anyone else to have to deal with this issue or worse."
