Meet “Harley” and “Blue Boy” (lighter/bigger/on left).. They’re brothers, and they love to play.
Sometimes the best tactic to get one’s brother to chill out, is to not take it out on him, but your own foot… note that Blue Boy is biting his own foot with a vengeance. I have several photos of this, he did it for some time.
And there you have it, a bit of a puppy play session. Cute eh?
