well the breed standard is not to exceed 7lbs, but if your not plannning to breed or show its fine if its just for a pet any dog will do as long as you love your yorkie
well mines is 7 months and barely weighs 2 lbs but she was very sensitive when she was smaller if she got too excited she would just get weak and start shaking i would give her karo syrup and keep her warm and it went away it happened 3 timES And i thought i was going to loose her everytime and i havent spayed her b/c i wanted her to have pups so if she has more than 1 one since ill give oe to my mom i wanted to keep the rest and get her fixed but if she doesnt get anny bigger and heavier i dont want her to go through a c-section and i dont want to risk her life and i guess shell never have pups
so i guess as long as shes healthy its okay my next yorkie i will make sure wont be too tiny
