The Mastiff is an easy going, good natured family dog. He is very good, obedient student, loves company and is especially good with children and the elderly.
He was used as a watchdog on large estates in his native England. That's why his nature is sort of "wait & see", dignified and observant.
The keep of such a "gentle giant" is a lot easier than you might think. However their sensitive spirit does need a lot of love, affection and attention to fully develop.
