Dogs

Molosser is a category of solidly built, large dog breeds that all descend from the same common ancestor. The name derives from Molossia, an area of ancient Epirus, where the large shepherd dog was known as a Molossus. See also: Hunting Dog Breeds, Photos

Molossers typically have heavy bones, pendant ears, a relatively short and well-muscled neck, and a short muzzle.

A Mastiff is a large molosser dog known for size and strength. The terms "the Mastiff group" and "the Mastiff" has been used synonymous with the term "molosser". As such, any molosser, including bulldogs, Great Danes, mountain dogs, pit bulls, and even small dogs such as the Boston terriers may be considered "Mastiff" in this broad sense.

However, the term is most commonly reserved for Dog breeds with the word "Mastiff" in their name including many of the largest of all dogs.
