Bullmastiffs are huge, powerful looking dogs that came about during 1860s England when owners of game reserves and large estates needed protection. From a Mastiff and Bulldog this breed was created to be large, quick, strong and intelligent enough to be able to subdue a burglar without maiming them. Although they are huge dogs, they make excellent apartment or house dogs because they are relatively low energy and don't bark unless the situation requires it. In fact, ideally, Bullmastiffs will always be indoor dogs since they will affectionately desire your presence and will not be as happy (possibly developing bad habits) if left alone for the whole day.
Members of this breed will be loyal and protective dogs to their owner or family and make perfect additions to households with children and other pets. They are not a hunting breed and do not display developed hunting instincts but can be trained to subdue intruders without injuring them. These guys are often described as independent thinkers and even stubborn, but truly they are very intelligent and eager to please you. It is imperative for you to take the time to train this breed and establish yourself as the leader from the beginning, gently but firmly. Besides some light hair cleanup little grooming maintenance is required, however, they are known to drool quite a bit. Besides the typical large dog issues of bloat, hip and elbow dysplasia, they may risk developing heart problems and some cancers. With routine trips to the veterinarian your Bullmastiff should live 8-10 years.
