Overview
The Bullmastiff was bred in nineteenth-century Britain by gamekeepers who crossed Mastiffs with Bulldogs to produce a dog fast enough to catch a poacher and strong enough to hold him without biting. It is a big, square dog with a short fawn, red or brindle coat and a dark mask, and the Kennel Club lists it in the Working group.
Modern Bullmastiffs are family dogs with a guardian's instincts: calm, affectionate and quiet at home, watchful of strangers, slow to anger and very hard to stop once committed. They are not high-energy, but they are not pushovers either.
Exercise and walking needs
An hour a day split into two steady walks is plenty for most adults. The breed is not built for stamina or speed and gets no benefit from long hikes or fetch.
Keep puppies and adolescents to short, gentle outings; they grow fast and carry a lot of weight on soft joints. Avoid stairs and jumping until the owner confirms the vet is happy.
On the walk
- Strength: Walk on a well-fitted harness or headcollar with a fixed lead. If the dog decides to go somewhere, you need leverage, not just a grip.
- Strangers: The breed watches people and may plant itself between you and someone it does not like. Stay calm, keep moving and do not let strangers hurry up to it.
- Other dogs: Usually tolerant, but some are dominant with large dogs of the same sex. Keep introductions slow and controlled.
- Heat: Heavy body, short muzzle. Warm days are a hazard. Early or late walks, shade and water.
Tips for professional walkers
- Plan a slow route with few surprises and places to rest.
- Carry a towel; most Bullmastiffs drool, especially after drinking.
- Watch for stiffness after walks and report it; joint problems are common in heavy breeds.
- Avoid walking straight after a meal and give a rest period either side of feeding.
What to ask the owner
- Has the dog had any hip, elbow, cruciate or heart problems?
- How does it react to strangers approaching you, and what command settles it?
- Does the owner want a rest around mealtimes to reduce the risk of bloat?
