There are at least five broad categories of Mastiff dogs. These include the Bullmastiff as well as the English, Spanish, Neapolitan and Tibetan Mastiff. The Bullmastiff is very similar to a British bulldog and was first recognized as a separate breed in 1924.
The English Mastiff is part of a separate breed and is a very powerful and large dog. Its lifespan, however, tends to be a little shorter than other dogs and usually ranges from 9 to 11 years.
The Spanish Mastiff is one of the oldest of breeds and historically was most popular as a guard and sheep dog. Like the English Mastiff, the Spanish variant is also very large and can be up to 140lb in weight.
The Neapolitan Mastiff has its origins in ancient Rome, at around 100 BC, and tends to be somewhat thinner than other Mastiff dogs, and has more loose skin, although they are usually just as large. Neapolitan Mastiffs can weigh up to 150lb.
The Tibetan Mastiff is a much rarer breed than other Mastiffs and may weigh up to 160lb. They also live longer than other Mastiffs. It is not uncommon for these to live until 14 years of age.
