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 Miniature Bull Terrier
Compact, muscular terrier with an egg-shaped head and triangular eyes. Bold, clownish and affectionate, with a strong will that needs consistent, positive training and early socialisation. Low-maintenance short coat, but demands daily exercise, mental stimulation and attentive health care.
