If y'all will allow me a moment to brag, Minty taught herself the most adorable trick. As a puppy I thought I would teach her shake and so I started by holding out my hand palm up, just to see what she'd do.
She looked at my hand, thinking, glanced at me, thinking, gears turning and turning in her tiny furry head, staring at my hand... then suddenly a lightbulb! She laid her head in my hand, looked up at me expectantly and wagged her little tail.
Well, was I supposed to tell her that, no, that was wrong? That that wasn't adorable and definitely deserving of praise and pets? Her chin was right there for the scritching!
I have since taught her to first bump as a variant of shake, and she's a champ at wait, but that one is still my favourite.
