Not too long ago I adopted a house dog to keep my wife company when I deploy. Here recently I started getting into shotgunning and small game hunting. He's just a mutt (part husky part something else), but I'd like to take him out with me. Not so much as a working dog, but more of a hunting buddy. However if I let him off of his leash he's gone for good, and he's not good enough on leash to take him through any brush. Can anybody give me some pointers to make this dog somewhat useful ?
