Summary
About Landseer
The Landseer is a giant, black‑and‑white water rescue and companion dog, calmer and more athletic than a Newfoundland. Gentle, people‑oriented and usually excellent with children, it needs space, regular grooming, steady training, and active owners willing to handle drool, mud and shedding.
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.
