My puppy is about 9 months old and he has all of the sudden started shedding. It is really driving us crazy. My vet told me that he could be loosing his puppy hair or he could not be getting enough fatty acid oils in his diet, so my vet gave me the fatty oil pills so maybe that will help. I know that yorkies are not supose to shed so has anyone ever had a problem like this? Any advice would be greatly appreciated.
