Bad Moon is a horror film released in 1996 about werewolves. Specifically, the film is based on a novel Thor, which tells the story from the point of view of the eponymous family dog.

The story starts off pretty simple; guy gets attacked by werewolf, becomes a werewolf. But then it becomes a lot more interesting when he moves back home and his sister invites him to stay at her home along with with her son and dog and he attempts to hide his curse from them whilst the dog becomes determined to protect them from him.
