The American Bulldog is an athletic, versatile working dog that is prized by farmers for their intelligence, working abilities, stamina, and protective nature. They are string and swift, capable of jumping heights of six feet or more. They typically measure between twenty and twenty-eight centimetres in height and can be white, brindle, brown, red, or tan in color. A powerful dog that needs intensive socialization and obedience training, this breed is best suited to an experienced dog owner. The American Bulldog responds best to firmness, fairness, patience, and consistency in training and will excel at tracking, hunting, schutzhund, weight pulling, and guarding.
