You really need to get on top of that kind of behavior early on. If it showing that kind of behavior give it a clip round the ear, as for chasing stock it just comes down to training if you dont trust it leave it at home and dont wreck the rest of your dogs, your mates dogs or the farmers trust. I hunt bull cross's and hunt them with other people who run the same type of dog we dont have fights well not often because we dont put them in the situation that would lead to a fight. I dont beat my dogs but I treat my bulls different than my others.
