American Bulldog

American bulldogs are highly energetic and more dangerous than many other dogs. These dogs can grow to be just around 30 inches tall and weigh over 100 pounds. They're big, powerful dogs who can be deadly when they attack.

During the 13-year investigation, 15 people were killed by American bulldogs, accounting for around 3.5 percent of all fatal assaults. Although this is a small amount, it is important when considering that this breed is rarely cited in conjunction with other deadly dogs. If you are raising an American Bulldog, be careful because this breed has a strong bite and can jump high and hard enough to knock an adult flat on their back. This dog is very loyal and dependent, but it can be dangerous and violent at times if it is not properly trained and socialized from an early age.
