Hive account@captainamazing I know what you mean about these small dogs barking at big dogs. It can get pretty frightening. One way I discovered to make sure you're alpha to your dog is to play tug of war and make sure to win. If you lose, the dog thinks he's alpha and then gets more aggressive until you start winning again. At least, that's how it was with my dog. He's not a Yorkie, though.
