11 Most Muscular Dog Breeds

1. American Pit Bull Terrier

Also called Pitbulls and Bullys, American Pit Bull Terriers are one of the bulkiest yet sweetest dog breeds.

While American Pit Bull Terriers may look ferocious, they are complete sweethearts and super friendly even with strangers, which, admittedly, may not make them the best guard or watchdog. However, most of the time, their sheer presence is enough to keep strangers at bay. Today, these dogs are commonly found participating in legal sports like dock jumping and weight pulling. 

Pitbulls make excellent pets as they are lovely, loyal, friendly, and love to please their owners. They are also exceptionally friendly and kind towards children.

Originally bred in 19th-century Germany as guard dogs, this breed has a strong build and daunting features. There is no accurate information on its ancestry, but it is believed that the breed we know today is a mix of Rottweiler, German Pinscher, and Black and Tan Terrier — all of which are evident in the strong frame of the Doberman.

Rottweilers have a reputation for being aggressive and trying to establish dominance over any dog of similar size and build. It is thus very important to properly socialize and train Rottweilers from an early age.

Renowned for being the fastest dog breed, the Greyhound can reach the speed of a cheetah at 40-45 miles per hour.
