"Bully dog" is an informal term used to describe a number of dog breeds and mixes thereof that share a range of physical and personality traits. The term “bully” isn’t a reference to their personality, it’s a reference to them being used for bull baiting in the 19th century.

Bully breeds descended from a now a extinct breed called the molosser. The molosser was a large, powerful dog used for protection and guarding in ancient Greece. The various bully breeds we know and love today all display physical and character similarities to this breed, to varying degrees depending on the other breeds in their ancestry.

If you’ve ever met a bulldog, pit bull terrier or boxer, you’ll be familiar with their loving, playful and fun personalities. Typically, bull breeds show remarkable tolerance to children and won’t flinch or become grouchy at the presence of an overenthusiastic playmate. That's a very good reason why bully breeds are popular pets. However, there are some important differences to note: For example, a pit bull is watchful and reserved, preferring to treat strangers with caution until he is confident they don’t pose a threat to his family. Bulldogs are more curious and are more likely to embrace a stranger. Boxers are alert and active, bullmastiffs much more sedate.
