We use Austrian/German tracking dogs (they've a wierd name) for tracking wounded moose and bears. The dogs will not track a non-lethally wounded moose or bear - they know if the wound/wounds is fatal - soemthing in the genetics or something - really an amazing animal. Coloured like a rotty or doberman - but more of a hound-ish dog. Wish I could remember the name.

They are incredible dogs - will 'bark' to let the guide know where they are if loose, but usually on a long lead. When finding/spotting a bear, they'll not bark, but growl instead, telling the guide the animal is still alive and a threat.

I'd imagine you would not want a dog on a lead when he finds the wounded buff.
