Anybody else's dog ever pull this trick? Vito, our Jack Russell, goes outside to the bathroom, comes back in, gets a treat, runs back to the door and goes around in circles like he has to go to the bathroom again, goes back outside but doesn't use the bathroom, runs back to the door, comes into the kitchen, sits down and looks up at the cabinet where the doggy treats are kept, thinking he's going to get another one. Does he think we're stupid?
