Well the yorkie standard is n ot to exceed 7 lbs, so I guess that's what most would want. but 3-5 varies from the small end to the normal end. Uni is 6 lbs and gets lots of comments she's "too big" t o be a yorkie.
and any smaller you get "are they teacups?" comments, oh well.
WTF is up with m y tyoing, there it goes again! OMG Ugh you know what I mean.
