I washed my dog and hartz oatmeal shampoo and he began having seizures and passed away the next morning. I had no clue that this shampoo is what could have made him pass away. I called my vet after reading about hartz shampoo and he says it very well could be what have caused the death of my beloved dog:-( We will no longer be using hartz products at all and I will make sure to tell everybody I can the same.
