Buck is all over the world seeing things he never saw before. For him it's new but refreshing, he gets to look at his wild not just the woods or the forest but life from all aspects of it. Buck has came a long way so he has really changed himself into a new person and he will benefit from it. how can a house dog be on his own with other wild dogs and survive, he did what he had to do to keep his head on that leash and not get it knocked off. If he chooses to return home he will be the top dog on the block.
