Well to me anything under 7 lbs is tiny!!!! And I'll admit I went looking for just that!! However I would never have paid the ridiculous fees many breeders were charging for their yorkies...
I went to a couple breeders I was already familiar with and one had a small little girl...as soon as I laid eyes on her...I Bought her on the spot!! For me it was not just about size but it had everything to do with the face!!! I had looked at ALOT of yorkies before I chose Tulip... The fact that she is small (2lbs 4 oz at 6 mo.) doesn't bother me...she's been the picture of health since I got her at 12 weeks.. She is as hardy as Daizy..and seems to play rougher..lol Alot of times I have to pull her off of Daizy..
However...I do NOT in any way think she's better than 10 pounders...but she's my baby..and I love her! And we are pretty sure she'll make it to 3 lbs.
To the OP:
Maybe it's the Public's perception that you are thinking about...not the individuals!!
