Clint, I think, you are comparing your dog with another dogs. Let me tell you, each & every dog have different personality. I have a female rott pup, she is just 4 month old. she is very friendly with every one (i mean strangers), which is not a quality of a rott. But now she has started gaining her qualities, if a stranger comes with me then she plays with him but if a stranger comes alone & try to approach house or her she don't allow at all.
