I only used the Hartz oatmeal shampoo once on my chihuahu Rosie and She broke up on this nasty rash that turned into an horrible skin infection. She couldn’t stop itching, crying, my poor aby was so uncomfortable. She just finished a 2 week course antibiotics. Im glad nothing worst happened. But seeing so many horror stories is absolutely heartbreaking. Something needs to be done to make this company to stop selling poison!
