Big at 4 1/2 lbs??? Wow,some people are just naive
 
I honestly think that those who think that a 4lb dog is big should sit and do some reading

 4 1/2 lbīs is very very small,even for a yorkie and those that ask you "whats the matter with her?" SHOULD be corrected because these are the kind of people that want a yorkie for all the wrong reasons.
I know when someone LOVES this breed because they show interest in them,they WANT to learn,they ask questions and accept advice..those who are looking for a 2lb pet (and think THATS the standard) just because its super cool,it fits in a bag and will get them attention DONT love yorkies at all,they just want a fashion accesory..these are the ones that cant be educated unfortunately
