Summary
About Saint Bernard
Large, gentle mountain dog developed by Swiss monks for rescue and companionship. Calm and affectionate, especially with children, but very big, drooly, and heavy shedding. Needs moderate exercise, careful joint and health management, and close inclusion in family life.
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.
