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 Mastiff
The Mastiff is a giant, heavily built guardian dog, calm and dignified yet deeply devoted to its family. It is watchful rather than aggressive, needs gentle, consistent training, moderate exercise, and space. Its short coat is easy to maintain, but drool, health care, and costs are significant.
