Krenshars

Krenshars are canines that resemble wargs or large wolves. Unsuspecting adventures who cross these dogs soon find they have an interesting self defense mechanism. They can stretch the fur over their face back over their skull to reveal a terrifying looking skull. Krenshars are often domesticated by larger humanoids like trolls and ogres and used as watch dogs.
