I just finished the first season with my year and a half old chocolate lab. This being my first dog to train myself, I did what I could preseason and took a lot of notes for off season training this year. His biggest flaw and my biggest obstacle is how bored he get hunting. Not long after the decoys are set he’s trying to chew on every stick he can reach (including the tree behind him) and whining a lot. What do I need to do to break him out of this? He hasn’t flared any ducks yet but he’s also not been around a ton either.
