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 Bull Terrier
Muscular, egg‑headed Bull Terrier comes in standard and miniature forms with a short, easy‑care coat. A lively, people‑focused, clownish companion, it needs daily exercise, mental stimulation, clear boundaries, and attentive care for skin, joints, and hearing.
