A friend of mine has a Lab, Pit mix and he is an overall good dog. He was never trained to hunt but as far as general manners he is great. Since he has some Pit in him he is a little more protective of things but with proper training this can be avoided. I dont mean he attacks, but he barks, unless you are a child. If you are a child or under 4ft tall that dog will not only lick you to death but he would probable help you rob the house.
So they can be good dog if trained, jst like any other dog, just be awair of the breed and whatch for any bad habbites that may be coming out. Good luck
