For a long time we used hartz shampoo on my dog buddy. He started having cognitive issues a month before his death and we didn’t know what was causing it. A week before his death he had a mini seizure that we took him to the vet for. The vet couldn’t find anything wrong. A week later at age 6 Buddy suffered multiple seizures and died in my arms. Hartz is an evil company, they allow thousand of animals to die due to their products and do nothing about it.
