Jigsaw and Indy both have ambidextrous (sp?) tails. Their curls are relatively tight and for the majority of the time stay to the right side. But they also will easily switch to the left and stay there comfortably for a while, especially while out walking. If they shake themselves, their tails will usually correct themselves, but the "wrong" way doesn't seem to bother the dogs. Do other basenji's tails behave similarly?
When Indy is in the show ring (altered classes only now) I've always debated whether to try and deliberately put his tail to the left. It would probably stay there for long enough. But for some reason I've never been able to bring myself to. It's funny, but it feels like that would be betraying his true self.
