Some mild flirting between the Princess and Bob. At least one kiss between Bob and Elsa.

A few people are killed (mostly off-screen).

The werewolf (always pictured as a dog) gets into a fight with Bob. The action is strictly G-rated. At one point blood is seen running down the hand of the Princess, which then morphs into the front paw of the werewolf.

Most of the men are seen in period smoking.

It is doubtful anyone would be frightened by anything in the film, even when the wolf is killed (off-screen).
