Bailey has always been quick to learn. I believe this to be a Yorkie trait... of course
So far we have taught him to: sit, lay down, stay, come, roll over, spin, dance, play dead and jump. For each of these tricks I have also used a hand motion, so that I don't even have to speak in order for him to do a particular trick. How about your Yorkie... what tricks have you taught him/her to perform?
