History
The Bullmastiff was originally called the 'Gamekeeper’s Night Dog' as they were used to catch poachers. The base stock of the Bullmastiff was 60% English Mastiff and 40% Bulldog. They were created in the late 1800’s. When the need for gamekeepers and the Bullmastiff declined they were used in sport. Someone would run off into the undergrowth and after a short time a muzzled Bullmastiff would be released to see if the person could be found. They were not trained to maul or kill, but to overpower their target. All the records state the dog never lost. The Kennel Club in Britain first recognised the breed in 1925, and the American Kennel Club gave them recognition in 1933. 
Intelligence
The Bullmastiff can be stubborn and firm handling is required from puppyhood. They can also be quite headstrong and boisterous, especially during adolescence.<

Overall Exercise
40 - 60 minutes per day.
This dog should not have long walks or be allowed a lot of free exercise until it is at least 12 months old. It has to be remembered that even when this dog is 6 months old, and is relatively large, it is still a puppy. Too much exercise too young can lead to bone and joint related health problems in later life. They have an average demand for exercise, only requiring a few walks per day. They do enjoy exercise and games with the family.
