I ahte to bring u my Rudy again, but....he's a Border Collie/Australian Shepherd/Great Pyrenees mix (mother is a border collie/pyrenees mix, father was am aussie/pyrenees mix. He's got the intelligence of the Border Collie (and the stubborness) but the size of the Pyrenees. He's gorgeous, but damn! I'm so glad I researched all 3 breeds before I got him!
