Last week, we bought Hartz products. We used them on our west highland terrier. She then started to lose her hair on her hind legs and was not acting like herself. We took her to the vet they said they think she had a reaction to the Shampoo and spray. which we only used on her once and used the spray a little on her bed. When we left they called us to tell us that from her blood work she is having kidney failure. She is at the animal hospital now on IV’s and being monitored closely. We will get her in the morning and take her to our regular vet. They will do more blood work to see if she has showed any signs of improvement. We need to spread the word!!
