Great canine family members are trained in the difference between protection and aggression. Dog owners are wise to teach the dog to control overreactions to people who are unfamiliar in the park, on the sidewalk or in the family home. Rushing the fence with teeth bare while growling ferociously is unacceptable behavior for the dog.
An American Pit Bull Terrier, also known as APBT, can be an excellent addition to your home, but like other breeds, proper introductions to other pets you have is crucial. Obviously, an intro with a puppy or young, well-socialized dog is easiest, but if you want to adopt an adult, finding one that will live in harmony with your other pets will not be a problem.
