Training at a young age is a must, and I mean starting at 3 months or less with obedience. They are all good dogs for your started purpose, but in my opinion GSDs are the ones tyat want to please their master most and most protective. But I still love my Rottie, very protective but doesn't care as much what you want. They take a much stronger hand to train.
