It's Valentine's Day, both White Fang and his mate, Collie, celebrate being together for over a year. Although White Fang is half wolf and half dog, he has a good heart. Collie, wary of wolfdog before, has now realized that he has learned much more from their master, Weedon Scott. After all, she has understood that her lover has been through a lot in his life, before he came to Sierra Vista.

But they got married, have six most beautiful and lovely puppies on the farm. Later that afternoon, both White and Collie have just put their puppies in the basket for nap time. After that, the two lonely romantic couples went for a walk in the forest. They have found an undisturbed place. Then they looked at each other with their half-closed eye contact and rubbed their noses together softly, feeling very happy to be together.

White Fang: "Happy Valentine's Day, Collie, my pretty sheepdog."
Collie: "And happy Valentine's Day, White Fang, my lovely wolfdog."
