Do Dogs Actually Smile?

Relaxed open mouth grins with tongues out reflect positive doggy smiles, laughs and smiles.

Shape Matters

Dogs widen eyes and soften eye wrinkles to appear more "smiley" and cute to humans when feeling happy.

Bright Eyes 

Tail wagging, wiggly body, play bows, bouncy run, lean ins and attentive expression accompany "smiles".

Body Language 

Dog smiles occur during and reflect enjoyable situations like play, attention, treats or reunions.

Situation Interpretation   

Dogs lack intricate facial muscles for nuanced expressions, inhibiting the complex smiles humans make.

Facial Muscles  

Some breeds like Bulldogs and Pugs have loose flews and facial structure giving the appearance of smiling.


People smiling and laughing can trigger doggy "smiles" in response showing their innate social nature.
