If he looks that well taken care of I'm sure his parents are scouring the town looking for him! Hopefully they will check with the animal shelters!!!
Thanks for keeping us up to date!!! Sorry it didn't work out for you........but as hard as it is to believe there are people out there that give up their yorkies....for whatever reasons....I've heard of quite a few in animal shelters!
When I was looking into shelters on the internet...I scoured a couple hundred miles away from me...and we ended up driving over 2 hours to get our dakota..........which is one of the most wonderful dogs ever...even tho she's not a yorkie! lol (can't hold that against her)
Good luck and hope you find that little precious you're looking for!!!
