The English Mastiff is the breed that is most commonly
referred to as simply the Mastiff. The mastiff has a
temperament that is calm and affectionate towards the owner.
Mastiffs are often referred to as gentle giants. They cen be
defensive of their master and family, but rarely attack, and
even then only attack to immobilize the threatening person.
The Mastiff needs activity and daily exercise and is good with
children and other dogs. The average life span for an English
Mastiff is 7-14 years.
A male Mastiff can weigh between 150-250 pounds and the
females weigh between 120 and 200 pounds. The largest Mastiff
ever recorded was in England at 343 pounds. Accepted coat
colors for Mastiffs include fawn, dark fawn brindle, apricot
fawn, and silver fawn. Non-standard colors of English
Mastiffs include black, blue brindle, and chocolate mask.
Brindles seem to be gentically dominant over solid colored
coats. All Mastiffs have a black mask covering their muzzle,
nose, eyes, and ears.
