Today's Role: Companion Dog, Guard Dog

History and Facts: It is believed that the Mastiff originated in Asia and was brought to the Mediterranean and the rest of Europe via ancient Phoenician traders. In Great Britain, breeders perfected the dog and began exporting it as a military and fighting dog around 2,000 years ago. Today the Mastiff is a good mix of a gentle companion and a protective guard dog.

Temperament / Behavior
The Mastiff is good-natured, self confident and gentle. Once a fierce guard dog, over time breeders have been able to adapt the Mastiff to family life. This breed is extremely intelligent and responds well to patient, consistent training. Guard training isn't necessary because the Mastiff is naturally protective and will know what to do in the case of an intruder or disturbance. The Mastiff rarely barks. When it does bark, you know its trying to tell you something. The Mastiff does not interact well with other pets, but can get used to other dogs if raised with them from a young age.
