As I understand it, 4 pounds is the small end of normal size for a yorkie, and smaller than that is when the concerns start to ramp up. If you are working with a breeder that did health checks on the sire and dam, the risks for problems popping up are somewhat lower. One of the concerns is smaller dogs are more difficult to safely anesthetize for things like tooth cleaning and spaying. You may want to ask your vet about that. |
