My good friend has one. That dog may as well be their fourth child...Has full run of the house privileges and sleeps on the bed with them too
That being said. People pay hundreds of dollars for my buddy to bring him on hunts with them. He's even traveled far out of state for it. I've never seen him in action, but I hear when he gets out of the truck in the field, he's all business.
Oh, he said he's the best security dog he's ever had and is great with the kids too.
