Understanding Whale Eye in Dogs: Signs Your Pet is Anxious

Whale eye is a form of dog communication through body language that can indicate anxiety or stress. Often, a dog will turn its head slightly, revealing the whites of its eyes in a half-moon shape.

Canine body language powerfully conveys a dog's feelings and thoughts to both owners and other animals. Continue reading to learn what spotting whale eye in your dog can reveal about your pet.

What Is Whale Eye in Dogs? 

"Whale eye" is a term used by dog trainers to describe when a dog's sclera (the white part of the eye) is visible. The dog turns its head slightly, maintaining eye contact with an object or person, and the whites of the eyes appear in a half-moon shape, typically on one side but occasionally all around. It's also known as "half-moon eye."

Whale eye isn't always easy to detect in all dogs. The eyes of brachycephalic dogs or those with short muzzles, might naturally show some white due to their physical structure. Additionally, any dog may glance to the side, momentarily revealing the sclera. If other signs of agitation are absent, the visible sclera might not indicate whale eye.

Signals That May Appear With Whale Eye 

A dog showing true whale eye will often display additional stress signals. These may include appeasement gestures like lip-licking or avoiding eye contact. The dog's hair may be standing up along his spine. He might also growl a warning or freeze in place rigidly.

What Whale Eye Means in Dogs

A dog with whale eye is usually anxious and uncomfortable with the situation. This indicates stress and possibly even fearful. Whale eye can be a sign that the dog will soon become defensively aggressive. An anxious dog is more likely to bite. If you notice this type of dog body language as you're approaching a dog, back off until the dog relaxes and becomes more comfortable, or at least until you can figure out what's going on.

Assess the dog's environment without approaching. Is there another dog or cat nearby? Is a stranger approaching? The anxious dog might hear something you can't, like approaching footsteps. A child might be reaching for the dog's favorite toy or a valuable chew or treat.

A dog might show whale eye if he is uncomfortable with what someone is doing to him, like being hugged, being petted in an area he doesn't want to be touched, getting examined by a vet, or getting his nails trimmed.

What to Do When a Dog Exhibits Whale Eye

Your dog hopes you'll notice his eyes and understand his message, urging you to resolve the issue. If you identify the problem, taking action is the best course.

If the issue is your action, simply stop. If another dog approaches in a public space, guide your dog away. Remember, your dog might also be tense, so gently coax them to move.

Scolding your dog is pointless and likely to increase his distress. Imagine whispering an urgent message only to face rebuke. When your dog shows whale eye, the issue usually stems from something external, not the dog.
