Sorry to hear about your dog's aggressive behavior. This breed, among others, has a tendency to be protective and territorial aggressive towards people. The causes can be related to the blood line or as a result of environment. Best bet here is to consult with your local veterinarian on a plan to help alleviate the problem through behavioral modification and medical management through neutering. There are also specific medicines available to help deal with certain behavior problems. You might ask your veterinarian for a referral to a veterinary behavioralist in your area, who specializes in these kinds of problems. Together, I hope they can lend you some solid answers to this difficult but serious problem with your dog. Please feel free to reach out for a consult with me if you have further questions. All the best, Steve Popish, DVM.
