The tiny trickle of information we have suggests the dog went after the bear. We don't know how the dog actually met his/her end.

The well-fed comment-o-sphere, naturally, has already proclaimed judgement. A mob with torches and pitchforks is being duly assembled.

As far as I can tell, we really have ZERO credible information. The 'papers can't even decide if he's a canoeist or overland trekker.

This is possibly shaping up to be the most desperate situation we have seen. The gentleman involved does not seem to be a rookie. I sincerely hope he recovers and can shed an instructive light on his terrible ordeal.
