Summary
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.
About German Shepherd Dog
The German Shepherd Dog is a medium‑large, athletic working breed, highly intelligent and trainable. Loyal and naturally protective, it needs extensive daily mental and physical exercise. It has a double coat with notable shedding and is widely used in police, military, and search and rescue roles.
