What Is the Difference Between the Old English Mastiff and a Bullmastiff?

I have looked at both breeds but can’t see a lot of difference between them. Why are they not considered the same breed?
Ah so a bullmastiff is 60% mastiff! No wonder they look so much alike. Thank you

Bullmastiff=IWas originally s a cross between the English Bulldog and Mastiff, hence the name. It is now a reconsised breed and is reconsided by AKC and is now consider an seperate Purebred!

Height: Dogs 25-27 inches (63-69cm) Bitches 24-26 inches (61-66cm)
Weight: Dogs 110-133 pounds (50-60kg) Bitches 100-120 pounds (45-54kg)

The Bullmastiff was obtained by crossing 60% Mastiffs with 40% Bulldogs in the country of England. Mastiff Bulldog types can be found in records as early back as 1795. In 1924 Bullmastiffs began to be judged. Three generations of breeding of Bullmastiffs was required for Bullmastiffs to be registered as purebreds. The Bullmastiff was used as a gamekeeper’s dog to track down, tackle and hold poachers. The dogs were fierce and threatening, but were trained not to bite the intruders. When the need for gamekeeper’s dogs decreased, the dark brindle dogs so good for night camouflage gave way in popularity to the lighter fawn coloration. It has been prized as a hunting guard, as an aid in army and police work, and is used as a watchdog by the Diamond Society of South Africa. Today’s Bullmastiff is a reliable family companion and guardian. It enjoys living with the family, with whom it comforts itself well.

English Mastiff=
Height: Dogs from 30 inches (76cm)
Bitches from 27 inches (69cm)
Weight: Dogs about 160 pounds (72kg)
Bitches about 150 pounds (68kg)

Found in Britain as early as the Roman invasion, the Noble Old English Mastiff was probably brought to that island by Phoenician traders as early as the 6th century BC. Since then, the Mastiff has been used as an arena gladiator by the Romans, in the bloody sport of bull, bear and dog combat, and as a sheep guardian, bodyguard, protector, and companion. A Mastiff came to America on the Mayflower and subsequently other dogs were imported. By the end of World War II, Mastiffs were almost extinct in England. However, with fresh imports from the United States and Canada, the breed is once again well established in today’s England. Some of the Mastiff’s talents include: watchdog, guarding, police work, military work, search & rescue, and weight pulling.

  1. Angel Barbie says:

    Bull mastiff came first! They then bred that with the bull terrier and came up with the bullmastiff.

    BULLMASTIFF – Intro: Bred to protect gamekeepers from the dangers of poachers, the Bullmastiff has developed into a useful working dog in a variety of organisations due to the manner in which they will calmly subdue and hold their target rather than attacking viciously.

    Size: Dogs should measure 64-69cm and bitches 61-66cm, with weights of 50-59kg and 41-50kg respectively.Looks: A large, powerfully built dog with a square, wrinkled head and muzzle. The Breed Standard specifies a short and straight back with powerful, straight forelegs leading to a purposeful, even gait.
    Health: Another large breed that is prone to Hip Dysplasia and Bloat.

    Cost: Minimum £600.

    Character: Protective and loyal to their family, the Bullmastiff’s inherent power makes them somewhat of a handful to manage although they should never exhibit unnecessary aggression. Excellent guard and watch dogs due to their suspicion of strangers and protective nature.

    Grooming: With their short coat little grooming is required beyond a daily combing to remove any debris and dead hair.

    Special care: With their size care should be taken to properly socialize them as otherwise they can cause all kinds of chaos!

    Exercise: Considering their size, relatively little exercise is needed. Two good length walks a day and any time running free will keep the Bullmastiff content.

    From the owner: "Wonderful guard dogs who simply love to share your home. We’ve had to be incredibly firm in training but I have noticed that scolding does not work as it would with other breeds. The Bullmastiff retains a strong sense of being, aware of its place and duties within the family. If you don’t like the idea of a slobbery dog then Bullmastiffs are probably not for you." Esme R, Ipswich

    MASTIFF
    Intro: A genuinely massive breed, the Mastiff (sometimes refered to as the English Mastiff) is descended from the Roman Molossians and has a long history as a guard, companion and fighter. The Mastiff is renowned for its intelligence and ability to identify a threatening situation.

    Health: As a large breed they are prone to Hip Dysplasia and Bloat although with care both of these can be avoided. They are also susceptible to certain eye and heart problems although buying from a reputable breeder should lessen the risk of inherited diseases.

    Size: Dogs should measure around 75-82cm, bitches at least 66cm and weighing between 70-90kg.Looks: The initial impression is one of power. A strong hindquarters and a broad, well-sprung body, visibly muscular chest. Their head is square and broad with distinctive wrinkles across the face. Colours are fawn, apricot, silvery fawn or fawn-brindle, all with a black mask across their ears, eyes and noses.
    Cost: Expect to pay around £800-1400 for a puppy. Feeding costs may also be quite high with this breed.

    Character: They are gentle and peaceable with their family, affectionate toward children and clearly courageous. The Mastiff has historically been bred as a guard-dog and these instincts are still strong, they will be wary and maybe even aggressive toward those strangers they feel threatened by.

    Grooming: Nice and straightforward, they simply require a quick brush once or twice a week to remove any loose hair and debris.

    Special care: Owning a Mastiff is a massive responsibility as they can pose a real threat to people if they haven’t been properly trained and socialized.

    Exercise: As a large breed they need lots of exercise but care should be taken to gradually increase the amount as they grow so as to avoid any increased risk of Hip Dysplasia.

    From the owner: "Your Mastiff will want to stay with you wherever you go, they are such loyal creatures. One thing you may have to watch out for is their propensity for knocking things over but with their size this can’t really be helped. They will slobber and drool all over your house and are far more likely to lick a burglar than bite them! Phil D, Southampton

    I hope it’s clear that when you buy one of those cute puppies in the pet shop window, you buy more than the puppy. You buy the budding physical and behavioral problems created by the bad genes passed on by untested parents whom you never get to see and evaluate.
    Worse than that, you buy into a profit-hungry industry that is hurting innocent animals. Simply out of good conscience, a pet shop should not be anyone’s choice as a source for a puppy

    There is a lot of difference in the size of them, and the look. The bullmastiff has originally been created by crossing with the mastiff.

    They are both fairly laid back but I would say the english mastiff would be the most laid back. Horizontal is the word usually.

    Love both these breeds and if you do get either then please go to a very reputable breeder as both breeds can have major joint problems when badly bred. Also make sure you do not ever overexercise one of these giant breeds in their growing period, building to about 18 months old before on full exercise.

    Lovely choice of breeds — just get a slobber towel ready.

  6. JenVT says:

    A mastiff (aka English Mastiff) is larger. It is taller and heavier. The bullmastiff is more compact. They both come in fawn and brindle but the main difference is size. Mastiffs are not mutts, the breed is recognized by breed clubs around the world, so disregard the answer that says otherwise. It is not technically called the "English Mastiff" but that is what most people refer to it as.
