3 years ago I was jogging and Porsche went off into a pond area, all of a sudden I hear Canadian Geese going crazy, I look over to the right and there was about 50 of them going after Porsche as she entered their nesting area.
I remember my first dobe swimming way out onto a lake to go after a flock of geese. He swam and swam til he got quite close, and then he suddenly seemed to realize that his head in the water was lower than the geese' bodies were, floating along on top. And he was out-numbered.
He looked at the geese; they looked at him. You could sense some heavy duty thinking going on.
Then all came to a decision--the dog turned around and headed back to shore; the geese swam off in the opposite direction.
