Bernese Mountain Dog

Part of the Bernese Mountain Dog’s appeal is just their sheer size – this pup can get up to 115 pounds. They love their family deeply and are generally a gentle giant, although they take a while to warm to strangers and they often alarm bark to warn them away.

This may make them a better watchdog than a guard dog, unless they’re specifically trained for what to do in the event of an intruder.
