Hi,
I have a 3lb. yorkie who is six months old... I'm hoping he gets bigger because 3 lbs. is TINY. If he ever got sick and needed surgery it would be quite an ordeal. His internal organs must be ridiculously small and would make him very vulnerable. So far he has been very healthy so I can't comment on health. However, regarding his size...It's a lot of work because he is EXTREMELY fragile. I have two other dogs and "teacups" are a whole different ball game. I love Preston and I'm so happy he's mine but at the same time I didn't realize what I was getting myself into with such a small individual. It's definitely something to think long and hard about...
Good Luck
