Bear started kicking his hind legs when we started giving him a treat after he does his business to help pee pad train him. Now he does it to make sure we know he's gone potty and since we are now trying to phase out the treats he will do it and we will tell him good job and he will look at us like "where's my treat??" if we don't give him one he'll walk back over by the pad and kick his hind legs again!
