I have a lab/hound mix, and it is a great dog. He is 5 months old and listens better than most 5 year old dogs. I taught him how to shake in literally two seconds, just had to grab his hand once and say "shake." I don't hunt with him, but I know if I wanted to I could because he is so easily trained. I don't ever use a leash and he does not wander any farther than I let him.
Another thing, he has a nose that would put any labs nose to shame. My room-mate has a 6 month old lab, and my dog will find any tiny scrap of food well before the lab even gets a whiff of it. This could come in really handy if you are talking pheasant hunting!
