1.General Description of the Bullmastiff
The Bullmastiff is a large, powerful breed with an alert and intelligent appearance. The dog has a muscular body covered by short hair. The tight coat is red, brindle, or fawn in color and the chest may have a small white marking. The breed has medium-sized, dark eyes and a broad, square shaped head with moderate stop. The ears are V-shaped and rest against well-built cheeks on either side of a flat forehead. The muzzle is approximately a third the length of the entire head and should be dark in color. Both the nostrils and teeth are comparatively large and the dog’s bite should be either a tad undershot or perfectly level. The topline is straight and level, and the tail is set high.
The Bullmastiff is a brave and stalwart dog, whose quiet and docile demeanor is best suited to a mature and even tempered family. Bullmastiffs are very gentle and kind toward children, but they also tend not to be active or playful; in other words, while the Bullmastiff is content to be a doting guardian, kids are likely to find the dog boring. On the other hand, it is these exact same qualities that have endeared the breed to so many adults who prefer a quiet and devoted companion that does not need constant attention and entertainment. This breed is neither friendly nor aggressive toward strangers and other dogs, and tends to be good with other pets, including cats. The Bullmastiff is aloof and guarded around strangers, potentially aggressive toward strange dogs (particularly between males), and accepting of house pets. The breed is also known to have a stubborn streak that can make training difficult.
3.Caring for a Bullmastiff
The Bullmastiff can be a bit lethargic, so it is important for owners to encourage activity (daily walks at a minimum) and monitor the dog’s meal size. Without proper care, this breed will put on weight very quickly. When purchasing food, make sure it is specifically formulated for larger breeds, as a Bullmastiff does best with a relatively low fat / low protein diet. Because this is a large breed, it is important to keep the dog’s nails short and to check the footpads regularly for cuts and other injuries. The Bullmastiff has a tight, shorthaired coat, so bathing and brushing requirements are nominal. Socialization with strangers and other dogs should begin as early as possible in the dog’s life. Bullmastiffs are susceptible to canine hip and elbow dysplasia, gastric torsion and entropion
