I think it depends on how small you're talking...we have 2 boys that are right at 3 pounds and they are both very healthy at 5 and 11 months. They didn't have any blood sugar issues and the vet says they're both healthy and strong. We had a little bit larger Yorkie for 12 years that, we later found out, was from a puppy mill and he had nothing but health problems all of his life, he weighed about 5 to 5 1/2 pounds. |
