Episode 1 of 6-part series for Channel 5/National Geographic

The Dog that Battled the Bear dramatically recounts the epic battle a husky dog waged against a black she-bear to save its sledge driver from death.

Paul Guitard was training his husky dog-racing team in the forests of Ontario, Canada when a black she-bear attacked, spilling him to the ground.

As the bear savaged Paul, all of his dogs ran on – except one. Lead husky, Grizzly, raced back to battle the bear, giving the badly-injured Paul the chance to escape up a tree. But bears can climb trees, too. So, Grizzly began what became a seven hour fight to fend the bear off and keep Paul safe.
