After a long day, coming home to my dog can make all the difference. Her tail wags excitedly, and she showers me with puppy “kisses” as a sign of affection. The cutest moment, though, is when I grin at her, and she seems to smile back. But do dogs actually “smile” like humans do? We consulted a veterinarian to find out what our furry friends are really trying to communicate with those adorable expressions.
Do Dogs Smile?
Yes! Dogs can indeed smile, but some breeds are more prone to it than others. According to veterinary behavior specialist Dr. Lore Haug, breeds like Doberman Pinschers, terriers, and cattle dogs often exhibit this behavior more frequently.
Dr. Haug explains that a dog’s smile is essentially an “appeasement greeting behavior” directed primarily at people, not other dogs. Dogs smile by pulling back one or both lips, sometimes showing their teeth, and this expression is often paired with other greeting behaviors, such as approaching, wagging their tails, or even whining.
The Meaning Behind a Dog’s Smile
Smiling in dogs can be a form of “active submission.” This is different from other submissive behaviors, like curling their body down or rolling onto their side. A dog may smile when they are feeling happy, but they can also smile in moments of guilt. If your dog gives you a submissive grin after doing something wrong—like chewing your favorite shoe—it’s likely because they want to avoid trouble.
Is It Normal for Dogs to Smile with Teeth?
Yes, it is completely normal for dogs to bare their teeth when they smile. However, this behavior can sometimes be misinterpreted as aggression. Dr. Haug notes that people may react with fear or confrontational behavior, which can inadvertently create defensive aggression in the dog.
To distinguish between a friendly smile and a threatening display, observe the dog’s body language. A smiling dog typically wags their tail in a wide, sweeping, or circular motion and approaches you with a relaxed demeanor. They usually won’t growl, though Dr. Haug has encountered dogs that make a “wheezy kind of grumbling noise” when they smile.
In contrast, a dog displaying aggression will have a stiff body, move slowly, and appear tense. A smiling dog, on the other hand, will exhibit a loose and wiggly posture, ready for affection rather than confrontation.
Conclusion
Understanding your dog’s smile can deepen your bond and enhance your communication with them. So next time your furry friend greets you with a goofy grin, remember they might just be expressing their joy, submission, or even a hint of guilt.
