Calm, devoted, courageous, naturally protective.
30–45 minutes daily.
Short coat, weekly brush. Drool requires towels.
Hip dysplasia. Bloat / GDV. Cardiomyopathy. Cancer (over-represented). Lifespan tragically short — 7–9 years.
Full Bullmastiff profile →Confident, calm, courageous. Rotties are famously affectionate with their own people (and lean — the "Rottie lean" is iconic) but reserved or aloof with strangers. Early, ongoing socialisation is non-negotiable. Not naturally aggressive — but they will defend if they feel they need to.
60–90 minutes of structured exercise daily, plus mental work. They excel at obedience, tracking and weight-pulling. Heavy bones and slow growth mean puppies under 18 months should avoid impact (jumping, jogging, long runs).
Short, dense double coat — moderate shedding year-round, heavier twice yearly. Weekly brush, more during moults. Bath every 6–8 weeks.
Hip and elbow dysplasia. Osteosarcoma (bone cancer) is sadly common — early neutering may worsen risk; many vets recommend waiting until 18–24 months. Aortic stenosis. Bloat / GDV. Lifespan is short for the breed (8–10 years).
