Joanne Barnaby was deep in the deadfall, smeared in mosquitoes and blood, dehydrated and near exhaustion, when she heard the call of a mama bear searching for its cub.

Barnaby couldn’t believe her luck.

Twelve hours earlier, she had been picking mushrooms in the remote Canadian wilderness when she had heard a growl behind her. She turned around and saw Joey, her faithful mutt, locked in a snarling standoff with a skinny black wolf.

For 12 hours, the wolf had pursued Barnaby and her dog through the wildfire-scorched forests of the Northwest Territories.
