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 Bullmastiff
Large, powerful guardian originally bred to catch poachers, the Bullmastiff is calm, confident and deeply loyal, often bonding closely with one person. It has a short, low‑maintenance coat, needs space, consistent early training and socialisation to guide its natural protectiveness.
