Summary
About Great Dane (Grand danois)
The Great Dane (Grand danois) is a giant, elegant dog, among the tallest breeds. Once a boar‑hunting and estate guard dog, it is now a loyal, people‑oriented companion. Calm indoors with moderate exercise needs, it requires space, careful training, health care and close daily companionship.
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.
