While spaying or neutering your dog isn't an automatic solution for aggression problems, it can make it easier to manage and train your pet. A dog's hormones are powerful influences on his behavior, and having him "fixed" prevents those hormones from dictating his mood and behavior. Whether your dog is a male or a female, it can make a positive difference.
A dog's surging hormones don't affect just his sex drive. Hormones can make him more territorial, more aggressive and less receptive to training and discipline. While intact males are driven by hormones all the time, females may become more aggressive during their periods of estrus, or "heat." When your get your dog spayed or neutered, you eliminate the compulsion to mate and assuage the feelings of aggression and anxiety that hormones create. When your dog isn't driven to aggressive behavior, he's less likely to bite and more likely to listen to your discipline.
