22. Terrier the Bull

Although you would recognize this appearance as the Target dog, the history of these little dogs goes back before the firm. When necessary, bull terriers are strong dogs that can deliver a punch. Keep a watch on them when playing with children or other animals because of their strength and high prey drive. The bull terrier has a history of aggression because it was raised to be a terrific dogfighter. However, if properly trained, these hounds can become loving pets that like to play. The owners of these dogs must exercise caution and vigilance around strangers, even when their canines are well-behaved inside their homes.
