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 Norfolk Terrier
The Norfolk Terrier is a small, sturdy working terrier with drop ears and a harsh, low‑shedding coat. Friendly, alert, and confident, it suits families and other dogs when well socialised. Adaptable to flats or houses, it needs daily walks, training, and regular grooming.
