It's funny, I used to see a ton of them before getting Vickie. Always by the local shopping center and our old neighbor (we recently moved) had one but I think she was sold as I never saw her in my last months of living on that street.
The only time I saw a yorkie near my home while having Vickie was about a month ago when one got loose and someone found her. Claiming we should take her ebcause we have a Yorkie. Um, no.
Where I live now, I see a lot of maltese, shih tzu, and chihuahua, but no yorkies unless at my vet who is 2 cities over.
