be sure he knows about YT.
I got to mention this...the last time I saw him trying to work with yorkies you could tell it was edited and pieced together. I truely think the 2 yorkies got the best of him. I think he is more used to working with big dogs and then to work with 2 hyper, quick moving, typical yorkies was a challenge for him.
that would be a good question... "are smaller, less timid dogs , (such as a yorkie) harder to work with?"
Oh and did I mention to make sure you advertize YT? wouldn't that be nice if he was to do a live YT chat session?
