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 Brussels Griffon
Brussels Griffons are small, sturdy toy dogs with humanlike, bearded faces and large dark eyes. Deeply attached and “velcro-like,” they thrive on close company, gentle, reward-based training, and moderate daily exercise. Coats may be rough or smooth in rich red, black, or black and tan.
