"The bullmastiff was bred to be a gamekeeper's guard dog who could track quitely, cover short distances quickly, and pin and hold poachers. He is now primarily a family companion with a calm, dependable disposition. A mature adult male will average 26 inches and 120 pounds. Maintaining such traits as alertness, wariness of strangers, strength, and agility, the bullmatiff needs a firm loving home and is not a dog for the fragile or timid."
