The Bullmastiff breed is also known as the “silent watchdog” as they remain very calm and quiet, and that makes them a perfect family pet. Being loyal and affectionate, these dogs possess high protective instincts that make them protect their family against any kind of threats. However, they do not attack in defence as their nature is to pin down the invader to tackle them rather than to hurt them.

Bullmastiff Breed Information

The breeding of Bullmastiffs was performed around the 1860s in England, when the gamekeepers needed a canine which had an impeccable tracking ability, run short distances in no time and pin down the trespassers or poachers without attacking them. They loved to have a dog which was much more aggressive and agile than a Mastiff, yet not very ferocious or bigger than a bull dog, to keep their game preserves and estate free from intruders. They are also known as the ‘Gamekeeper’s Dog’ as they were bred by crossing 60% of Mastiff with 40% of Bulldog. AKC (American Kennel Club) officially recognized it in 1934.
Bullmastiffs are good natured dogs that are highly affectionate and gentle with their family. They do not attack the intruder, but rather knock them and hold them down. Their calm nature makes them a best play mate for kids. They allow their owners to walk in front as a mark of respect.

Health and Care
The Bullmastiffs are huge dogs that have a lifespan of 8 to 10 years. They are generally healthy, but can develop some major complications like cardiac disease, hip dysplasia and elbow dysplasia. They are prone to cancer, eyelid issues and tumors. To identify the major health conditions, the vet will have to examine your dog’s eye, hip or elbow regularly. These big dogs tend to gain weight easily and hence you must avoid overfeeding them. Instead, give them smaller meals at regular intervals. They demand minimal coat care and regular walks on a leash. These dogs require ample space with soft bedding to stretch and rest. They tend to drool and snore. Keep your bullmastiff indoors during hot weathers and protect him from roads and traffic as he loves to roam about.
