wow you found a yorkie puppy in the street!!!! I'm glad you're doing all this to help him, poor thing. I really doubt it would have been dumped (I can't imagine somebody doing that!) but you know, things like that can happen believe it or not. Still, it's good that you posted flyers and all that. But I don't know if I want him to go back the his "owner" if that person was careless enough to loose him. Well, you know we're here to help, so, just ask!
Oh, please post some pics
