There's afew of us here that have them. They're a gaurdian of many types of flocks. They should be raised up with the animals they're to protect so a bond is started early. There's also the debate of can they be a pet and a working dog.Some say it's one or the other,which I can see. For a long time they were just a working dog with little human interaction,so they would bond with the flock. They will gaurd your home while your gone,I don't see anyone comming in with one of these in the yard. Boys get up to 120+lbs.,girls usually around 95+lbs & they don't eat as much as you'd think.They do take afew years to mature in size and coat.They can be stuborn and the barking can be a problem. I'd like to cart train ours for rides in the snow and a job is good for the mind.
