Mastiff Breed Information

A gentle giant, the Mastiff has a life expectancy of 8 to 10 years.

The Mastiff or a Mastiff-like breed is believed to have originated in the mountains of Asia around 2500 B.C. The ancient breed was used for hunting and guarding. Eventually, the Mastiff made their way to England where they were bred to be watchdogs. They were found to be very effective guardians of the home, but soon became cherished companions thanks to their gentle and affectionate demeanor.

The Mastiff is an enormous dog that weighs 140 to 220 pounds and measures 27 to 30 inches.

Grooming Needs
The Mastiff has a short coat that is easy to groom, but sheds heavily. The Mastiff needs to be brushed on a weekly basis and bathed occasionally. Many Mastiff owners find it easiest to bathe the large dog outside. Mastiffs should also have the wrinkles on their face cleaned and dried every day, especially after they eat.

Like all dogs, the Mastiff also needs basic grooming. Brush their teeth, clean their ears and trim their nails on a regular basis.  

The Mastiff’s size can be intimidating, but this breed is mild-mannered and respectful.  

The Mastiff is a wonderful family dog. They are not overly demanding of their family’s attention, but like being included in activities. Although they are large, the Mastiff gets along great with children and has a natural instinct to watch over them. Mastiffs are not particularly playful or rambunctious.

Mastiffs are calm and affectionate, but they were bred to be guard dogs and will protect their family if needed. Mastiffs are not aggressive and normally their size is enough to deter an intruder. However, Mastiffs will bark and are cautious of new people. They will place themselves between a stranger and their family member until they feel any threat has passed.

Training Needs
The Mastiff has a desire to please their handler, but is nonetheless stubborn. They are smart and will respond well to short training sessions and positive reinforcement.  The Mastiff is surprisingly sensitive and should be treated with kindness and patience.

The Mastiff also requires early socialization. They need to learn how to manage their size and get along with people and other dogs.

Activity Level  
The Mastiff is not a highly active dog and a short walk is normally enough for them. The Mastiff would rather take a nap than exercise; however they need regular activity for their health.

The Mastiff is particularly sensitive to heat and should not be exercised in hot weather. As puppies, the Mastiff needs to be watched even more closely. Mastiffs grow quickly and their bones and joints can be injured if they slip or fall.
