What readiness warrants against a shadow

A pack of dogs, well ahead of the hunters, treed the bear quickly. Utterly enraged by his predicament, the bear tore off pieces of himself and threw them to the dogs. This only increased their frenzy, and as the bear grew angrier he simply threw more of his body down below. When the hunters finally arrived, the bloody bear slipped from the tree, now just a drape of fur and sinew, bone and claws.
