How to Read Your Dog's Emotions

About this video

Dr. Karolina Westlund explains that the direction of a dog’s tail wag carries emotional information: a wag biased to the dog’s own left tends to be associated with negative emotional states, while a wag biased to the right tends to be associated with positive states. She adds that cats similarly tend to look at the world from the left in negative emotional states and from the right in positive ones.

Key takeaways

• Dr. Westlund explains left-biased dog tail wags tend to signal negative states and right-biased wags positive states.
• Dr. Westlund says cats show a similar left-right pattern in how they view the world.
