Pyrenean Mastiff Animal Pictures

Canis lupus

Like its Great Pyrenees cousin, these dogs originated as livestock guardians, charged with protecting their flocks from predators and theft.

As a good-natured guardian and gentle giant, the Pyrenean mastiff is often aware of its superior strength, though it hardly needs to use it.
