My female rescue Rat Terrier (or maybe she's a Feist like Callie) Tinkerbelle can do all that stuff standing on one foot.  Heck, she could probably do it with one paw tied behind her back.

Not really.

Still, maybe she is a Feist.  Some people call her that.  And she is very interested in squirrels.

Also, like Callie, she loves to sit up straight against me and get her chest and belly rubbed.  On that part, they could be twins separated at birth, except that Tinkerbelle is about 50% white.  But she's faster than Callie and a much sloppier kisser.  It's not easy to be careful enough around her.

Does it actually help to know the mechanics of all this?!
