I got a wierd one here. I've been training my lab for waterfowl hunting for almost 10 months now. He's does single, double and blind retrieves no problem, is steady when shooting until i release him but i have one problem. He goes absolutely nuts when i get him to heal beside me and call. The wierd part is that he is fine when i use a mallard call, its when i use a goose call that he goes crazy. He barks and runs around in circles for some reason. Any advice??
