Ends with the hero dog being loved and cherished by humans the way all hero dogs should rather then the dog going into the wild where he will end up as snackiees for some wolf pack.
Netflix did an animated White Fang a couple years ago. https://www.netflix.com/title/80245121
Pretty good.
On a note very similar to White Fang and Call Of The Wild, go see Togo. https://www.disneyplus.com/movies/togo/7jEeXqS5aEVr
Tale of an unwanted sled dog proving himself to his master via tremendous tenacity & courage.
I like both the stories but prefer Call of the Wild. I will have to look into the animated White Fang. Did they change the drunken Indian who sold him for firewater into a MAGA hat wearing white dude?
I believe that Buck actually became the Alpha leader of a wolf pack.
