Bullmastiff
Description
The Bullmastiff is a large, muscular dog with a short muzzle and a solid build, weighing between 100 and 130 pounds. Originating in 19th-century England, this breed was developed to quietly track and hold poachers without causing injury, blending about 60% Mastiff and 40% Bulldog traits. Their imposing size is balanced by a calm, stable temperament that makes them excellent family guardians. Despite their bulk, Bullmastiffs are surprisingly low-key indoors and adapt well to apartment living if given sufficient outdoor exercise. They’re naturally protective but rarely bark, preferring to block intruders physically rather than confront aggressively. Their loyalty to family is strong, and they tend to be gentle with children, though they can be stubborn and respond best to patient, positive training methods.
Grooming
Bullmastiffs have a smooth, short coat that sheds lightly to moderately year-round, so weekly brushing with a rubber curry or bristle brush keeps loose hair under control. Bathing every 4 to 8 weeks is enough to maintain cleanliness without drying out their skin. Nail trims should happen every 2 to 4 weeks, and ears need checking and cleaning monthly to prevent buildup. Their coat colors range from fawn to red brindle, often with black masks or markings; these don’t require special stain care but do highlight dirt more easily on lighter fawns. Pro tip: Use a damp cloth to wipe drool and keep facial folds clean, reducing odor and skin irritation. - Weekly brushing with rubber curry or bristle brush - Bath every 4–8 weeks, avoid over-bathing - Nail trims every 2–4 weeks - Ear cleaning monthly - Wipe facial folds regularly to prevent buildup

Walking
Bullmastiffs need about 50 minutes of walking daily, ideally in a single session to suit their moderate stamina and avoid overheating. They’re not built for long, fast runs but enjoy steady, purposeful walks that engage their natural guarding instincts. A consistent routine helps manage their weight and keeps them mentally stimulated without pushing their limits. Example routine: A 10-minute warm-up stroll around the block, followed by 30 minutes of slow-paced exploration in a quiet park, finishing with 10 minutes back home to cool down and relax. This balances physical activity with mental engagement while respecting their lower endurance.
Boarding
When boarding a Bullmastiff, provide a crate at least 48 inches long to accommodate their large frame comfortably. They prefer predictable routines and slow introductions to new people, so staff should approach calmly and avoid sudden movements. Enrichment should include two active play sessions daily combined with scent or brain games to keep their minds sharp and reduce boredom. Their playstyle is steady and deliberate rather than frantic, so activities should focus on controlled interaction rather than high-intensity games. Staff should monitor for signs of overheating and ensure the environment remains cool and quiet. Consistency and gentle handling help Bullmastiffs feel secure away from home.
