Well, with 1 being anybody's lap puppy, and 10 being an attack dog, I'd say Bailey's a three. She's very friendly and just about willing to meet any one or any dog. She really surprises me when she acts aggressive (barking) or scared (barking, backing up, pulling me away), but since she is so very friendly, I tend to trust that something is wrong with the people she's negative towards. Having said that, she's misjudged a few that I knew were scoundrels and new acquaintances where my spidey sense is tingling, but hers isn't. Some of her overt friendliness is because she's a puppy, she hasn't had enough life experience to tell her what's up.
She doesn't bark at kids or neighbours when she's looking out the front window, but if you come to the door, she goes off like a five alarm fire. Once I've greeted the person she's fine. She'll sniff and take pets, and if the person really loves dogs, she'll settle in for a major love fest.
I expect that because I'm friendly and out going, she is. I think the owner has more to do with the tone than the breed, though in what I've read and seen, the breed tends toward calmness, non-biting, and curious watchfulness. My dog stares people down. She studies them. Given a little maturity, she'll probably become more aloof and more of a guardian.
