@Kipawa:
People have asked me if Kipawa was a Shiba Inu. I was also asked if he was a fox.
I get shiba inu a lot, and he has been mistaken for a fox a few times too. The first time I walked him in my home town, we passed two older men. One did a double-take and just stopped. "Is that a fox?" Of course, smart a** that I am, I said yes.
A lot of people guess some sort of terrier mix. Actually, the first vet that I took him to thought that he was a terrier mix. She had heard of basenjis but had never actually seen one.
Most often, people just ask what he is. I guess the breed is so striking that they can tell that he's a PB.
