| DescriptionThe American Mastiff has a much dryer mouthed than other mastiffs. The
dryer mouth is due outcrossing the English Mastiff with Anatolian
Mastiff, which occurred early in the development of the breed. The
American Mastiff is a large, massive, and powerful dog. The head is
wide, heavy and rectangular in shape. The eyes are amber in color.
Darker the better. The ears are rounded and set high on head. The
muzzle is medium size and well proportioned to head and has black mask.
The nose is black; It has a scissor bite: . The neck is powerful, and
slightly arched. The chest is deep, broad and well-rounded, descending
to the level of elbows. The ribs are well-sprung and extend well back.
The back is straight, muscular and powerful, with well muscled and
slightly arched loins. The forelegs are strong, straight and set well
apart. The hind legs are wide and parallel. The feet are large, well
shaped and compact, with arched toes .The tail is long, reaching the
hocks. Puppies are usually born dark, and lighten as they grow older,
some becoming very light fawn by age one year; some retain dark hairs.
Colors are fawn, apricot and brindle. White markings acceptable on
OriginDeveloped by Fredericka Wagner of Piketon, OH at Flying W Farms by
crossing the English Mastiff with an Anatolian Mastiff. The resulting
puppies had a firmer, tighter lower lip line and did not drool as much
as the average Mastiff; selective breeding thereafter kept the dryer
mouth.
Temperamentquiet, calm, loving and loyal. Protective, but not aggressive.
Temperament
The American Mastiff love children and are totally devoted to their
families. Dignity rather than gaiety; quiet, calm, loving and loyal.
Protective, but not aggressive; they are non-aggressive except in those
instances when their family, especially the children, are threatened.
In those instances they become courageous defenders. They are wise,
kind and gentle, patient and understanding, very loving with their own
people, neither shy nor vicious, they are loyal, and devoted. Since
these dogs are of the Mastiff type and grow to be very large, this
breed needs an owner who knows how to display strong leadership.

Known Health ProblemsAmerican Mastiffs tend to be healthy happy dogs with fewer reported
incidents of many of the health problems you see in other large breeds.
Conditions for LivingAmerican Mastiffs do just fine in an apartment with daily exercise, a
walk will do, or a run in a fenced in yard. As they grow older they
tend to become a little lazy. They are relatively inactive indoors
("couch potatoes") and a small yard will do.
Exercise RequirmentsMastiffs are inclined to be lazy but they will keep fitter and happier
if given regular exercise. Like all dogs, the American Mastiff should
physical energy. It's in a dogs nature to walk. They should always be
leashed in public.
