White Fang

When White Fang - part wolf, part dog - gets separated from his family, he must find a way to survive on his own. In a harsh Canadian environment that means kill or be killed. Tough surroundings and cruel masters make White Fang increasingly more aggressive and wild, but Weedon Scott, a kind gold hunter, sees the dog in him and attempts to tame him. Released in 1906, White Fang - companion novel to The Call of the Wild - was immediately successful, especially among younger readers.
Ethan Hawke starred in the 1991 film adaptation as the wolfdog's friend, and in 2018, Netflix released a beautiful animated movie, introducing children to work of Jack London.
