Why do people regret getting an American Bully?

Although the American Bully is very friendly to its owner, tolerant and gentle with children, quiet without being dull, and excellent at guarding and daily companionship, it is fairly combative and its obedience weakens after adulthood. If not trained well before age one, it may later ignore the owner, and with its solid muscles and great strength, situations it can’t be controlled may arise. In addition, while the Bully is good with its owner, it is fierce toward other people and other dogs, so when out you must always guard against it biting someone.
