I had sent my black lab into a friends yard to chase away a bunch of geese. I would say there had to be 50. Let’s just say he doesn’t like geese anymore. And my neighbor learned to deal with geese in his yard.
It was funny at first, but the geese wouldn’t leave him alone, and I had to go out there and get my dog away from the geese. Those things can be mean when they get in big groups.
