I think the dachshund would serve as an excellent distraction. ;-) For one thing, dachshunds often make a hell of a lot of noise when they're upset, and that would help draw the bear's attention to the dog, I shoud think, allowing the human to discreetly withdraw. On the other hand, a frightened dachshund will often run straight to its owner for protection, so that could be a problem.

You have confirmed exactly what I always suspected about bears. I don't want to meet them at all, period, ever...
and I want a good 30/30 in my hands loaded and ready if I'm ever in bear country and on foot.
