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 Bull Terrier
Muscular, egg‑headed Bull Terrier comes in standard and miniature forms with a short, easy‑care coat. A lively, people‑focused, clownish companion, it needs daily exercise, mental stimulation, clear boundaries, and attentive care for skin, joints, and hearing.
