Thanks everyone!
He certainly does love tricks and training, and he'll do almost anything!
The reverse Peek-a-Boo is the one right after the ball trick. (he turns and backs between my legs) Dont ask me why but he seems to prefer doing things backwards. I have taught him to back around my legs, and do backwards figure eights between my legs, but he has yet to figure out them in forward. And his reverse crawl came before the forwards crawl... Silly guy.
He talks to me constantly, so i've put some sounds on cue. He snaps his teeth if I ask "Do you want it?" and says "Momma" if I ask "are you viscious?" he growls, and snaps and snarls... it's funny!
