Wolf and dog (IMAGE)
Caption
A wild gray wolf (left) and a domesticated Bernese Mountain dog (right), highlighting some common facial differences between the wolf and domesticated dogs. Most domesticated dog breeds have ears that lie flat, display a range of fur patterns and colors, and have a shortened snout. Red arrows indicate the levator anguli occuli medialis muscle, a muscle not found in the gray wolf that supports eye gaze communication between dogs and humans.
