The Bullmastiff isn’t quite as large as his close cousin the Mastiff. Still, standing as high as 27 inches at the shoulder and weighing between 100 and 130 pounds, this is still a whole lot of dog.

The American Mastiff is a large, powerful dog with a wide, heavy, rectangular-shaped head and a powerfully muscular build. The breed has a deep, rounded chest and well-sprung ribs. Their limbs are well-built, straight, and well-muscled, and their burly necks are thick and slightly arched

The Great Dane is one of the best known dog breeds in the world, in addition to being one of the tallest.  Despite the breed’s name, it was developed in Germany, not Denmark.  Originally bred to hunt boar and wolves, the Great Dane is now much better known as a loving family companion.
