I have yorkies and I use the best human shampoo and conditioner I can find for them. I would never consider putting any kind of dish soap on a dog. Dish soap is for removing oil and grease. Your dog needs some of its oils or its skin will dry out. Then it WILL itch and scratch. Have you taken the poor thing to the vet? if so, did you ask about using dish soap on your dog? I KNOW what the vets answer would be, and I suspect YOU know it too.
