The story development was really terrible. I mean it is right that somewhere in the history we made kind of coexistence living with dogs and yes that has probably happened while there wasn't such species as dogs so we mad friends with their ancestors, the wolves.

But how? Well we can only guess. However we can also certainly say the way this movie is showing us is the last possible one.

Of course people who consider their apartment puppies like their children can easily digest the idea of prehistoric puppy like wolves but the fact is otherwise. So, stop manipulating people's mind please. First we have locked up these free and capable creatures in apartments after turning them into dolls and now after we think of that as a right for us, we make history the way it endorse our previous lie to ourselves.
