Mastiff

The Mastiff is an extremely large dog in both height and girth, broad and deep in body, full of substance and with large strong bones. He combines grandeur with good nature. A very intelligent dog, he is not excitable, but is affectionate towards his owner. He requires plenty of human contact and good food and is best suited to a home where there are opportunities for exercise.
