The 38 Most Dangerous Dog Breeds In The World You Should Know About

24. Bullmastiff

As the name suggests, the Bullmastiff is a cross between a Bulldog and a Mastiff. This hound can reach a height of 27 inches from shoulder to ground and a maximum weight of 100 pounds. In the 19th century, these dogs were deployed to deter poachers. Although these dogs have been educated as defenders, they can still form close bonds with their owners. They did this by developing and displaying an aggressive and authoritative look. However, if this breed is not properly socialized or trained, it can revert to its original state and become dangerous even to its family.
