I've had many dogs over the years but just bought a couple of Great Pyrenees puppies to use as livestock guardian dogs from guardian stock. I've been really shocked at how low-key these dogs are, even as puppies. Easy going and likable but have the goods if needed for protection. I can see why a ewe would allow them around its lamb.

With that said, I would get two of these in that they seem to need the social interaction. They also seem to be a little stubborn with an attitude that they know what's best so seem a little more difficult to train than many dogs.
