These massive dogs were bred to protect everything from temples to flocks, and they’re not cheap.
A small bark won’t do much when you’re guarding a Himalayan caravan or a South African farm. That’s where mastiffs come in. They’ve been bred for centuries to stand between danger and whatever they’ve been told to protect. But these dogs aren’t just big—they’re sharp, loyal, and often surprisingly affectionate with the people they trust.
You’ll find mastiffs in almost every corner of the world, each one adapted to its own climate, terrain, and threat level. Some were made to face down wolves. Others were trusted to protect entire estates. And the price tag? Let’s just say these dogs earn every dollar.
