I thought about driving to Ft Collins to get a shiba from a rescue there, but the descriptions turned me off. They were all like, "this dog will not come in your house, will fight with other dogs, even its mother, and hates children". So, I adopted a boxer/whippet mix instead. Shibas are cute dogs, though.
I've heard the same things - this one is pet store puppy who was "rescued" from her original owner, and she's super sweet; aloof but very affectionate, loves to play, and does pretty well with other dogs. I have seen mean ones, though - a lot of apartments won't allow them, assuming they're just small akitas. I love her, though, she's a little princess and a hilarious character.
