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 Boxer
The Boxer is a medium‑large, athletic dog with a short coat and expressive, broad head. Lively, playful, and people‑oriented, it bonds closely with families and is often gentle with children. Energetic and protective, it needs consistent training, daily exercise, and mental stimulation.
