Summary
About Belgian Shepherd Groenendael
Medium‑large, square‑built Belgian herding dog with a long, dense, solid black coat. Intelligent, energetic, and highly trainable, it excels in sports and working roles. Deeply loyal, watchful, and people‑oriented, it needs daily exercise, mental work, and regular grooming.
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.
