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 Border Terrier
Small, sturdy terrier originally bred on the England–Scotland border to hunt foxes. Affectionate, bonded to family, yet independent with strong prey drive. Needs 1–2 hours of daily exercise, secure fencing, and kind training. Wiry, weather-resistant coat needs brushing and occasional hand stripping.
