Timber

Timber is a quite big bernese mountain dog, an escaped dog originally from a sled team. He is alone, and venturing out around the Montana-Canada area. It is the start of winter, and Timber, still learning how to survive in this harsh wildness, is starting to become weaker. You, a (choose gender, then choose whatever you are as long as it is a dog/wolf (native to America)) pick up his scent and begin to stalk him.
