If he can't control his dog at my favorite fishing hole I'll ask him to leave and if he doesn't leave there's Treaspass Laws therefore he can explain his actions to the Local Sheriff's Deputy maybe even getting a Free Ride in a Patrol Car to the nearest Crow Bar Hotel.

I've found the 99.9% of the fisherman and the Game Warden at my Fishiing Hole will back me up in this matter as I own the Fishing Hole in SW Washington.
