Madison sure is a cutie! I fell in love with Yorkies by a male Yorkie who is now in LA. He hadn't been taught anything because he was so spoiled
He had one ear up and one ear down and was obsessed with tennis balls.
I would find out what Madison knows and if there is a favorite toy.... does he know how to fetch and dig?
Pssst! Between you and me, most fosters end up adopting their furkids!
