Can Dogs Know How to Smile?

We're going to delve into the science behind smiling pooches, along with signs that often lead people to believe their pups are grinning.

If the sides of your dog's mouth point upwards, that often, but not always, signifies that all is well. You can learn even more from your pup's tongue. A tongue that hangs loosely combined with a mouth hanging open can point to a good, happy mood. 

Although dogs don't actually smile like humans, they sometimes happen to make expressions that look like smiles. You may see some behaviors in your dog that lead you to believe your pup is smiling. If your pup has all their teeth bared, that’s usually a warning sign telling you to back off. However, you may also see forms of “smiling” after giving your pup treats or petting.

In wolves and other canines, a "smile" indicates nervousness or even signals the acceptance of subordination. As descendants of wolves, dogs also are also internalized to interpret smiles this way.

The expression we call a smile is really just an indication that the dog is not threatening to overturn the status quo. Alpha dogs or leaders of the wolf pack don't really "smile" because these doggos think of themselves as our equals and have no need or desire to signal subordination. 

Researchers have ultimately concluded that dogs don't actually smile the way humans do. What we see is the result of submissive behavior and automatic responses, rather than an enjoyment of happiness.

Additionally, a dog's smile may indicate another feeling, like anxiety or nervousness. If your dog is "smiling" while also panting heavily, whining and chattering their teeth, you may want to consult your veterinarian.

Although your pup may not experience happiness the same way humans do, it is possible to train your dog to "smile."

Also, some studies have revealed that our dogs do mimic our facial expressions to some extent. If you have a clever pupper that tends to copy you, why not try to put in some smile time? Make sure there are no distractions, have your dog sit, and give them some over-exaggerated grins while saying "smile" right after. 

If they begin to make a similar expression, immediately reward them with a small treat and praise. Repeat the sessions regularly, but keep them fun and short to be the most effective - and always end on a high note!
