Callie can pick up a trick in less then 15 minutes. Right now she know sit, stay, down, beg, roll over, jump through the hoop, spin, leave it, shake with both front paws, and high five with both front paws, go to bed, and then she knows a lots of commands to keep her out of trouble like leave it, no, don't go off the carpet and others. I think Yorkies are very smart! This is what Callie did for a talent show
