English Mastiff Dog Breed Information

The English Mastiff, which originated in England (obviously), is one of the world’s largest dog breeds. This giant dog has a noble, gentle, and devoted behavior and is large-boned and beefy. Mastiffs are gentle companions and family defenders who do not exhibit hostility, making them ideal family pets. These brave but well-mannered canines can fit well with most households.

English Mastiff


The mastiff is a breed that has been bred in England for over 2000 years. The Mastiff (or its progenitors) may, however, be traced back to ancient times, with images on Egyptian monuments and comments by Caesar during his invasion of Britain. Though historically regarded as a laborer and watchdog, this exquisite species was formerly used for fighting, especially gladiatorial combat.

They were later seen in dogfights at Westminster in London. Today’s mastiff is a lover, not a warrior, and dogfighting was outlawed in the United Kingdom in 1835. Mastiffs’ current lineages date back to the nineteenth century, when they were no longer bred for aggression. Mastiffs may have arrived in the United States more than 200 years ago, but they were not formally recognized by the American Kennel Club (AKC) until the late 1800s.

The breed is known as an old English mastiff, an English mastiff, or simply a mastiff. According to the 1989 “Guinness Book of Records,” the heaviest dog in the world was an English mastiff named Aicama Zorba of La Susa, who weighed 343 pounds and stood 37 inches tall at the shoulder. This record will stand because the organization stopped recognizing pet record sizes in 2000.



These dogs have remained remarkably pure throughout the ages, which is perhaps why the traditional light-brown tones, along with the black mask, has become such a familiar attribute of dogs throughout the years. The English Mastiff, with its short coat and generally predictable color, is unquestionably a low-maintenance breed. Male English Mastiffs can weigh 150-250 pounds, while females can weigh 120-200 pounds.

The large size of the dog breed has also been a favorite of many noblemen and leaders, who have had their photos made with their dogs at their sides, providing proof that the English Mastiffs alluded to in past times correspond to what we know about their history today.

English Mastiffs are instinctual guardians, and will usually position themselves between their owners and other people out of instinct. Despite this propensity, the Mastiff is popular because it can be a friendly and devoted guardian of the home on other occasions, making it an easy “big” dog to get along with.

Regular exercise is necessary for Mastiffs, as it is for any dog, but it is crucial not to overwork these enormous dogs due to probable hip and joint problems. Some people find the Mastiff’s size daunting, but if size doesn’t concern you, you can find both a great friend and an instinctive guard dog for your house, making the Mastiff’s disposition incredibly flexible.

Health Treatment

Responsible breeders have strived to maintain the highest quality breed standards as set by kennel clubs such as AKC. Dogs bred according to these standards tend to inherit genetic diseases. Among the diseases that need to be considered include:

  • Hip dysplasia: An abnormality in the hip socket, which can cause pain and arthritis
  • Elbow dysplasia: An ocular condition that causes the eyelids to roll inward.
  • Gastric dilation-volvulus: Bloat
  • Weight Gain: Feed measured meals twice a day as more-active Tosas need more food; less-active need less
  • Diabetes
