I have a two year lab named Bailley .Having never trained a hunting dog she still has turned out pretty good.About a week ago I noticed when she hears the birds coming she points in the direction they are coming form.I do not know how common this is ,but since her hearing is so much better than mine I keep a close watch on her.The best one was when I was out changing the decoy spread I was not watching her.She came up and jumped up on me.Before i could correct I saw see was pointing up and a few seconds later I heard the birds.I still have some things I want to try and teach her ,but I think I have a keeper.
