  1. Working
  2. Bullmastiff
The Bullmastiff is a purebred dog that falls within the larger Working dog breed group.
Working group: Working dogs encompass a wide range of different breeds- but they all were bred to assist people, so they are used to working hard. It is important for them to feel they have a "job" as their roles traditionally have varied from rescuing people to pulling sleds. Because of their large size and intensity, they may be a handful for first time dog owners. On the other side, they can be trained well, so any owner who can exercise and dedicate to training their working dog, will be well rewarded. A common misconception may be that the working dog's jobs are only in physically challenging jobs; actually working dogs can also make excellent service dogs, since they are also kind and attentive to their owners.
