Bully Breeds: Myths, Facts, and the Truth About These Loyal Dogs

Bully breeds often get an unfair reputation. For decades, these strong, athletic dogs have been labeled as “dangerous,” even though most are gentle, affectionate, and deeply loyal to their families. This guide breaks down what bully breeds really are, why they’ve been misunderstood, and what makes them such devoted companions for the right pet parents.

What Is a Bully Breed?

Bully breeds are a group of dog breeds that trace their roots back to ancient Molosser dogs—large, muscular working dogs bred for protection, hunting, and companionship. Over generations, selective breeding led to the modern bully breeds we know today, including:

American Pit Bull Terrier

One of the most recognized bully breeds, the American Pit Bull Terrier is known for its strength, intelligence, and devotion.

They’re protective of their loved ones but rarely aggressive, preferring playtime and companionship over conflict.

Why Are They Called Bully Breeds?

The term “bully” comes from the bull-baiting sport popular in historical England, where dogs were bred for strength and courage and competed against bulls in fights. After bull-baiting was outlawed in the early 19^th century, these dogs were bred for companionship and work, not fighting². Today, the “bully” name reflects heritage, not behavior.
