Appearance

The AKC Standard for Bullmastiffs states this breed is, “a symmetrical animal, showing great strength, endurance, and alertness; powerfully built but active.” They are large and powerful dogs, but are not overly heavy or lumbering. They have broad, wrinkled heads with short, dark muzzles and a slight underbite. Bullmastiffs ears are dark in color and pendant shaped. Their tales are set high on the body, taper slightly and should reach to the dog's hocks. The coat is dense, short and comes in fawn, red or brindle. Most dogs will sport a handsome black mask.

Size and Weight

These large dogs stand from 25 to 27 inches at the withers for males and 24 to 26 inches for females. Males weigh in at a hearty 110 to 130 pounds and females weigh slightly less – between 100 and 120 pounds. Show dogs should always be squarely proportioned.

Coat and Color

The coat of the Bullmastiff is dense and short and sheds moderately throughout the year. They come in three colors, fawn, red or brindle and they have dark muzzles and ears. Sometimes they sport small white marks on the chest.

Grooming Needs

Bullmastiffs make up for their food bills in what they save their owners by way of grooming. Regular brushing will keep their average-shedding coat under control. Their wrinkles should be kept clean and dry, and they only require bathing as-needed. Dry shampoos can be used to keep them smelling fresh between baths. The ears should be monitored weekly to ensure that they are not red or irritated, and a veterinarian-approved cleansing solution can be used to prevent infection. Bullmastiffs are prone to bad breath, so weekly brushing of the teeth is often necessary to keep bacteria from building up. Active Mastiffs will wear down t heir toenails naturally, but if nails click on hard floors, it is time for a trim.
