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 Scottish Terrier
Scottish Terriers are small, sturdy, low‑slung dogs originally bred in Scotland to hunt vermin. Recognizable by their long head, prick ears, and wiry double coat, they are loyal, independent, and reserved with strangers. They need regular grooming, moderate exercise, and patient, positive training.
