BREED DESCRIPTION & INFORMATION
Note: The breed registries indicated above are the most recognized all-breed registries. The breed may also be recognized by other registries not indicated here. For further details about dog registries, please see the document: Dog Breed Registries in North America.
* The FCI is the World Canine Organization, which includes 84 members and contract partners (one member per country) that each issue their own pedigrees and train their own judges. The FCI recognizes 339 breeds, with each being the "property" of a specific country. The "owner" countries of the breeds write the standards of these breeds in co-operation with the Standards and Scientific Commissions of the FCI, and the translation and updating are carried out by the FCI. The FCI is not a breed registry nor does it issue pedigrees.
Males 25-27 in (63-69 cm) at the highest point of the withers
Females 24-26 in (61-66 cm) at the highest point of the withers
Males 110-130 lbs (50-59 kg)
Females 100-120 lbs (45-55 kg)
Females are feminine in appearance, of somewhat lighter bone structure than the male, but should still convey strength.
The Bullmastiff comes from a cross between the Bulldog and the Mastiff. Developed for the pupose of having a dog who could guard like a Mastiff, have the courage of a Bulldog, and be faster and more agile than the Mastiff. He was mostly used by gamekeepers in Britain to warn them of the presence of poachers and help them in a fight. Known as the "gamekeeper's nightdog", he was a silent, agile dog that could attack on command, knock down a man and hold him without mauling or biting. He has also been used as a police and army dog and as a guard dog by diamond companies in South Africa.
The Bullmastiff has an aristocratic, attentive and intelligent appearance. Powerful, active, alert, fearless and courageous, he is however, docile and laid back with those he knows. The Bullmastiff is extremely devoted, loyal, and affectionate to his family. Today, the breed is primarily a companion dog who is an excellent guard dog. With his natural guarding abilities and a somewhat stubborn nature, the Bullmastiff is not for everyone and early socialization and training is very important for this breed.
The number one killer of Bullmastiffs, along with many other breeds, is cancer. Some of the most common health concerns found in this breed are:
- Joint problems including Hip Dysplasia; Osteochondrosis Dissecans (OCD); and Panosteitis (Pano)
- Immune system dysfunction
- Lazy whelpers & difficulty with breeding
- Cancer and heart conditions
- Eye problems (i.e. entropion, ectropion, PRA)
- Bloat/gastric torsion
If you are considering the adoption of a Bullmastiff puppy, or any breed, it is very important to be selective in choosing a responsible and reputable breeder. Ensure that the prospective puppy's parents have all health clearances. Breeding of any dog should not be done until after they have been proven to be free of evidence of significant hereditary diseases. (For more information on selecting a breeder, see the articles on the main Breed Listing and Breeders page.)
