I have two, both males. Legend is almost 13 and Aesop is 8 months. I've not had dog aggression issues with either..both are well socialized and can and do go most anywhere with me without worry. While both are protective of the home (Legend more than Aesop, since Aesop is still a pup) neither are overly so. For instance, they'll bark at the door, but once I answer the door, they're fine with whomever I invite in.
They're independant if compared to a retriever or the like, I suppose, but both of my boys are very much 'people dogs'. They're usually within 5 feet or so of wherever I am. And they like to know where we are..if we're in the same room, Aesop will either lay nearby or in the room with us. If we're in different rooms, he periodically checks each of us to make sure all is well.
I've also had no problems training them to do anything. Neither 'tests rules' or is pushy, or any of the other things people were so quick to warn me of years ago when I brought Legend home. Neither has known a harsh training method, and I think that shows in their behavior also.
Both of mine are from breeders who focus on temperament and are splendid family dogs. (not the same breeder) I think it's a breed that can really be affected negatively by BYBs. I've never once worried when taking either out that there'd be a problem..and they've been around some goofy people.
While not a breed for everyone (I don't think any breed can really fit into every family, though) they're a breed I won't be without.
