Mastiff

Breed overview

A mastiff is a large and powerful type of dog. Mastiffs are among the largest dogs, and typically have a short coat, a long low-set tail and large feet; the skull is large and bulky, the muzzle broad and short (brachycephalic) and the ears drooping and pendant-shaped. European and Asian records dating back 3,000 years show dogs of the mastiff type. Mastiffs have historically been guard dogs, protecting homes and property, although throughout history they have been used as hunting dogs, war dogs and for blood sports, such as dog fighting, bull-baiting, bear-baiting, and even lion-baiting.

Breed facts

• The Fédération Cynologique Internationale and some kennel clubs group the two types together as molossoid dogs; some modern livestock guardian breeds, such as the Pyrenean Mastiff, the Spanish Mastiff and the Tibetan Mastiff, and an extinct draught dog called the Belgian Mastiff, have the word "mastiff" in their name, but are not considered true mastiffs.
• Many older English sources refer to mastiffs as bandogs or bandogges, although technically the term "bandog" meant a dog that was tethered by a chain (or "bande") that would be released at night; the terms "mastiff" and "bandog" were often used interchangeably.
• In the twentieth century the term "bandog" was revived to describe some large fighting mastiff type dogs crossed with any bulldog in the United States.

Personality and behavior

Care planning: record what your dog enjoys, how they greet visitors, and how they respond to new places. Add notes after walks and training so you can see their habits over time. Where this profile includes behavior research, use the same named measures when comparing your shortlist.

Exercise and activities

Care planning: build a weekly routine with walks, play and time to explore. Enter the minutes and sessions that work for your dog, then compare the weekly total with your available time. Keep notes about the activities your dog enjoys and adjust the routine together.

Training and enrichment

Care planning: choose one everyday skill to practice and keep a record of each session. Note the cue, the reward your dog enjoys and what went well. Rotate familiar games and new activities, and use your notes to choose the next small step.

Coat and grooming

Care planning: use the coat details above to discuss a grooming routine with your groomer. Record brushing sessions, baths and appointments in the app. Add the tools you use and your preferred schedule so the whole household can follow the same routine.

Breed history

Historical and archaeological evidence suggests that mastiffs have long been distinct in both form and function from the similarly large livestock guardian dogs from which they were most likely developed; they also form separate genetic populations. In the twentieth century the term "bandog" was revived to describe some large fighting mastiff type dogs crossed with any bulldog in the United States.
