Violence & Gore
Mild
Lots of fighting and some bloodless, non-graphic onscreen deaths.
At different times, two horses are killed by wolves. Some blood.
Despite this being labeled as a kids show, it gets more and more dark and violent as it goes. By season 6, you might as well say it's not a kids show.
Profanity
None
The S word is signed in sign language. If you don't understand sign language it is still heavily implied.
Alcohol, Drugs & Smoking
None
There are quite a few scenes of drinking and alchohol through the show.
Frightening & Intense Scenes
Mild
The show is mainly kid-friendly in seasons 1-3, but then more important characters start dieing, and the show gets a lot more intense and sad, making it pretty much not a kids show.
