My puppy is biting his hair off of the back of his lower body and now he has started biting his hair off of his tail. What could be the problem. He was on revolution medicine and when he was at the shelter for a week they lost his medicine and I gave him some medicine form bio spot. We send him to the groomer and we also give him a bath once a week. He is a house dog, name Brownie. He only goes outside to use the restroom. Can you help us.
Thank you inadvance for your help.
This could be a flea allergy dermatitis. I recommend that you have your pet checked for fleas. vetcare
