Breeds of dogs that have a problem with biting include pit bulls, Rottweilers, German shepherds, huskies and wolf hybrids, according to Livescience. Others include malamutes, Doberman pinschers, chow-chows, Saint Bernards and Great Danes.
The pit bull is not one breed of dog; pit bulls include American pit bull terriers, Staffordshire bull terriers and American Staffordshire terriers, according to Livescience. These dogs were bred for herding, hunting dangerous prey and fighting.
The chow-chow, which originated in China, is a notoriously strong-willed dog that needs a firm hand when it comes to socialization, explains the American Kennel Club. Wolf hybrids, or wolfdogs, can be unpredictable and even aggressive toward their human owners, states the International Wolf Center.
