Some yorkies have a genetic or hormonal problem that keeps their hair from growing. It is brittle (breaks off easily) and thin. So no amount of premium dog food or shampoo is going to fix the problem. You may be able to help it with vitamins (specifically which ones i don't know) or medication. It may be something that you will have to take up with the vet. Also, it may require blood tests in order to determine the exact cause of the heredity problem. |
