Mastiff

The Mastiff is actually one of the oldest types of dog breeds. Their ancestor, the molossus, dates back almost 5,000 years. The molossus was a war dog, but today's Mastiffs are quite benevolent and gentle. Despite its size (the Mastiff can weigh up to 220 pounds or more), they are generally good-natured and docile. They are a self-confident, watchful, and patient breed that is gentle-natured towards their family. One of their signature traits is their drool-filled head shake, and they are also known to snore.
