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 Border Terrier
Small, sturdy terrier originally bred on the England–Scotland border to hunt foxes. Affectionate, bonded to family, yet independent with strong prey drive. Needs 1–2 hours of daily exercise, secure fencing, and kind training. Wiry, weather-resistant coat needs brushing and occasional hand stripping.
