American Mastiff Description
The American Mastiff was developed over twenty years
ago by Fredericka Wagner of Flying W Farms.
In the year 2000, the
Continental Kennel Club (CKC) recognized the breed as "purebred" and since that time
has only been bred American Mastiff to American Mastiff. American Mastiffs were
developed specifically to be loving family companions. They are
large and powerful, yet very gentle in nature.
For a large breed dog, the American Mastiff has a relatively "dry mouth" and
excellent life expectancy (10-12 years average).
The American Mastiff requires little exercise. As puppies, they grow so
quickly and their bones develop so rapidly that they spend a lot of
time sleeping. They will wake up, play for a little while and then they
are asleep again. As they grow older, they can exercise more and
when full grown they will go for long walks with you but jogging is not
their thing. They are calm and quiet in the house; therefore,
though large, they make an ideal house pet. The American Mastiff
does well in a wide range of environments, from an apartment with walks
in the park, to a farm or a home with a big yard.
The American Mastiff is a wonderful family pet and a noble watch dog.
This breed does not bark senselessly, but if a stranger approaches, the
American Mastiff will be there to determine whether he is friend or foe.
With proper socialization, they are accepting and non-aggressive to visitors. However, the American
Mastiff is very positive in his expression of protection; they "read" their owner
and if the owner is uneasy about a visitor, the American Mastiff will not accept the visitor.
In spite of their great size, the American Mastiff is sensitive
and affectionate; they live to please those they love. Nothing beyond your
tone of voice is ever necessary to discipline. They thrive as a member of
the family and are totally devoted companions, especially with children,
being very patient, forgiving, and understanding with them.
The American Mastiff is truly a Gentle Giant.

American Mastiff Physical Standard
||The American Mastiff is a large, massive,
powerful dog with a moderately broad head, drop ear, wide set kindly eyes of brown or amber color, the
darker the better. This dog possesses a powerful neck, wide deep chest, and muscular back. Tail is
wide at the root, tapering to the end, hanging straight in repose, forming a slight curve.
The overall appearance should be of proportions slightly longer in body than in height.
||Height at maturity is typically
32 to 36 inches for males with an average weight of 180 but can exceed 200 pounds. Height at maturity
for females is typically 30 to 34 inches with average weights between 140 and 180 pounds. Larger or
smaller sizes for both males and females are acceptable provided the dog is in good proportion
and structurally balanced.
||Scissors bite preferred, but a moderately
undershot jaw should not be faulted providing the teeth are not visible when the mouth is closed.
||The coat must be short and dense.
As in other mastiff breeds, a puppy may have a longer coat; this is known as a "fluffy" and is
extremely rare but not considered a fault.
Fawn, Apricot, and Brindle. Puppies are all born dark and lighten
as they grow. Some dogs may become very light fawn by age
one year; some retain dark hairs (not a fault). White on foot, chest,
nose and chin is not a fault.
Muzzle must be dark in color, darker the better with same color around the eye
orbits and extending upward between them, referred to as the "Black Mask".
All American Mastiffs must exhibit the black mask.
Strong, set wide apart, heavy boned. Feet are large, round, and compact.
In movement, the gait denotes power and strength; rear legs drive while forelegs
track smoothly with good reach
The American Mastiff is a combination of grandeur, good nature, and gentleness.
These dogs portray dignity rather than gaiety. They are neigher shy nor vicious.
The well trained American Mastiff is calm, controlled, confident, patient, and loving
with their family, especially children. They can be aloof toward strangers. A well-socialized
American Mastiff is friendly yet sensitive and alert to changing situations. They are not
aggressive by nature but will defend their family if necessary. These dogs respond to threats
with judicious warnings and courageous action if needed.

The American Mastiff Breeders Council
The American Masiff Breeders Council (AMBC) was formed in 2002 to help protect
the breeding and proliferation of the Flying W Farm American Mastiff.
was that unscrupulous people would trade on the excellent reputation of the breed
that Fredricka Wagner had developed for their own purposes or greed.
Beware of breeders who are crossing Mastiffs with more aggressive breeds such
as Pit Bulls to create large aggressive dogs. These breeders sometimes advertise under
the name of American Mastiff, but they are not the CKC (Continental Kennel Club)
American Mastiff created by Fredricka Wagner. Also beware of the Mastiff breeds
Carnaris and Filo Brasilerio which tend to be more aggressive in nature.
Be sure that any American Mastiff can trace its lineage back to
Flying W Farms
where the breed was founded by Fredericka Wagner and is registered with the
Continental Kennel Club (CKC). For a listing of breeders approved by the AMBC,
