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 Belgian Griffon
Small, sturdy toy dog from Brussels with a humanlike “monkey face” and big eyes. Rough, wiry coat in black or black and tan. Deeply attached, sensitive, and people focused, they are lively, intelligent, alert watchdogs who thrive on gentle training, company, and regular grooming.
