Animal rescuers in Lake Tahoe, California, rescue a dog missing for four months in the wilderness. Russ, a black pit bull mix, went missing last August just before the Caldor wildfire hit the area, and his owner thought he’d never see his dog again. Last month, a skier spotted a dog trapped in the snow and rescuers from Tahoe PAWS snowshoed up the mountain to make a daring night-time rescue.
