Who is the father of Collies’ six puppies? Describe the last scene of the novel using details from the text.

I think White Fang is the father. As he walks again, he sees Collie and a litter of puppies. One puppy walks forward towards him, touching its nose to him. White Fang licks it on the nose. Everyone from the house cheers. White Fang's weakness takes him over, and lies on the ground, letting all of the puppies climb over him and bask in the sun.
