My dog (puppy) is eight months old. He has lost the hair in between his paws and now seems to be losing the hair on top of them also. He also seems to have lost some hair on his muzzle or face. At first we thought that was from him putting his nose to the ground when he sniffs. I looked it up online and am going to try out a new/better/different food in case of a food allergy. Does anyone know of any other possibilities?
