In the past, big size and strength were often desirable factors to breed into dogs, making them feared protectors and efficient hunters. Consequently, there have been many giant dog breeds created in the world over the centuries. There is no universal height or weight at which a breed is officially classified as a giant dog breed but some groups define giant breeds as those heavier than 100 pounds (45 kg). Their height and weight can vary greatly though, some breeds are stout and heavy while others are tall and lean. The heaviest dog ever recorded was a St. Bernard named Benedictine who weighed an incredible 366 pounds (166 kg).
