Sid, a 6 week old puppy, seemed to think he should be alpha over all dogs, and most people as well. Alas, when doing this around a 3 year old 45 pound pure muscle pit bull, the result is some time with a beagle on his back learning he may not be in charge.
And just to be clear, Stella was very nice about flipping him. Enough force to do it, not enough to hurt him. She taught him his lesson, with no harm done, except to his puppy pride.
