Summary
About Bullmastiff
Large, powerful guardian originally bred to catch poachers, the Bullmastiff is calm, confident and deeply loyal, often bonding closely with one person. It has a short, low‑maintenance coat, needs space, consistent early training and socialisation to guide its natural protectiveness.
About Bernese Mountain Dog
Large Swiss farm-bred dog with a strong, balanced build and a thick tricolour coat. Affectionate, people focused, and usually gentle with children. Needs moderate daily exercise, cool climates, regular grooming, and kind training. Health screening is crucial due to joint issues and cancers.
