I don't know why this mod didn't exist earlier. Pet Your Wolf, as the name of the mod suggests, allows you to pet your wolf. You can now give your friendly canines some much needed head scruffs simply by pressing P on your keyboard (You can change this in the keybinding menu). If you pet your wolf for an extended period of time, your wolf will recover health. This means you can keep your adventures going and not have to worry about food.
This mod requires you to have the Obfuscate library installed.
