As much as I hate to admit it, I'd have to agree with Kay here.

I don't think loyalty is defined to any one breed, and I don't think a single dog has it as a set standard. Every breed is loyal to some degree, some just might be more affectionate than others.....which obviously makes their "loyalty" easier to notice. Ask any dog owner you know, I can guarantee you that they would tell you in a second that their dog is loyal.
