Guides for your Mastiff

The story behind the Mastiff

Large mastiff-type dogs have been kept in Britain for a very long time, described by Roman writers and later used through the medieval and early modern periods as estate guardians, hunting dogs for large game, and in the baiting sports that persisted until they were outlawed in the nineteenth century. Country estates maintained their own strains, and the modern breed was consolidated from these during the Victorian era as dog showing developed. Both world wars reduced numbers in Britain to a critical level, and the breed was restored substantially with dogs imported back from North America. Kennel Club and AKC recognition are long established. The Mastiff today is kept as a companion and guardian, with breeders paying attention to the health consequences of extreme size.

Originally bred for: Estate guarding, Big-game hunting, Property protection. You can trace how working roles shaped today’s breeds across our dog guides.

Feeding a Mastiff

Growth control is the central concern, so puppies need a large-breed formula and disciplined portions rather than rapid gain. Adults do well on two moderate meals with rest either side, kept lean because every surplus pound loads joints and shortens comfort in a dog this heavy.

Watch for: No characteristic ingredient allergy is recognised. Giant deep-chested breeds carry a raised risk of bloat, making meal size, feeding pace and rest around meals more important than recipe. Any diet change, and any growth plan for a puppy, is best guided by a veterinarian.

Mealtime extras: training treats worth keeping in your pocket, and a slow feeder bowl if your dog inhales dinner. Everything else lives in our dog nutrition and feeding hub.

Living with a Mastiff

Day to day, the basics matter most: how much exercise your dog needs, how often to get out for a walk, and how much sleep is normal.

For play and enrichment, browse chew toys built for strong jaws and interactive toys for rainy days.

Gear that fits the breed makes life easier: a well-sized dog bed, a properly sized crate.
