I had taken my yorkie boy Dexter to the Vet Saturday afternoon (in Petsmart) and another lady was there with her yorkie male. The first and ONLY question she asked me was how much he weighed. I told her 4 lbs. and was a little taken aback as to why she would want to know! He's a little less than that, but I don't think that his weight matters all that much. In fact, my little girl Lily is 10 lbs! She's my little 'chunky monkey.'
Totally different weights yet both yorkies...
