Dogs show their teeth when happy because it's a natural way for them to express excitement and joy.

In fact, a study found that dogs who are happy and relaxed tend to display a more open-mouthed, relaxed smile, whereas those who are anxious or stressed may show a more tense, closed-mouthed expression.

Dogs have 42 teeth, and when they're happy, they often display a range of teeth, from the incisors to the canines, as a way of saying, "I'm feeling great!"

Understanding a Dog's Smile

Dogs can show their teeth when they're happy, but it's essential to understand their body language to avoid misunderstandings.

A dog's smile can be mistaken for a snarl if you're not familiar with their body language, so pay attention to their facial expression and overall demeanor.

Dogs may open their mouths and show their teeth, wag their tails, or make other happy body language cues when they're feeling content.

A relaxed, open-mouthed face with the corners of the lips gently pulled back and upward is a sign of a happy dog, according to Dr. Jeannine Berger, a veterinarian and animal behavior specialist.

This type of facial expression may include:

  • Mouth slightly open
  • Corners of the lips gently pulled back and upward
  • Teeth often showing

Dogs may show their teeth when they're happy as a way to communicate their emotions and show their contentment, but it's also possible that they're regulating their body temperature.

A true dog smile involves a retraction of the lips that reveals the top and (usually the bottom) teeth as well, and it's often accompanied by loose body language, but not always.

Smiles are often given when greeting people the dog adores, especially if the dog hasn't seen the person for some time, and they can be a sign of social, affiliative, and loving behavior.

Dogs tend to hold their ears back and keep their body lower to the ground when they're smiling, which can make them seem ambivalent or conflicted, rather than happy.

Smiles happen quickly and are subtle, making it a challenge to capture them photographically.

A dog grin, also known as a happy grin, is a common facial expression that can last for minutes and is characterized by a relaxed, open-mouthed face with the corners of the lips pulled back in a relaxed way.

Dogs often show this facial expression when they're relaxed and comfortable in a situation, and it's a good indication that your dog is happy.

However, panting dogs can resemble grinning dogs, so it's essential to pay attention to the context to determine if your dog is happy or just panting.

Smiling is contagious, and it's common to see people smile when they're feeling happy or relaxed. In fact, studies have shown that smiling can release endorphins, also known as "feel-good" hormones.

Here are some common signs of a happy smile:

  • Relaxed body posture
  • Soft, relaxed facial expression

A true dog smile involves a retraction of the lips that reveals the top and (usually the bottom) teeth as well. This kind of smile is a friendly expression and can be a sign of a dog's social, affiliative, and loving nature.

Smiling dogs tend to be social, affiliative, and loving, and they often give smiles when greeting people they adore, especially if they haven't seen the person for some time. This can be a sign that the dog is over the moon about the reunion and the opportunity to greet the person.

However, smiling dogs may also hold their ears back and keep their body lower to the ground, which can make them seem ambivalent or conflicted, rather than happy. Smiles are fleeting and subtle, lasting only a second or two, and can be challenging to capture photographically.

A dog grin, on the other hand, is a happy, open-mouthed face of a jolly dog, and it's often a sign that the dog is relaxed and comfortable in a situation. This facial expression can last for minutes and is often accompanied by a relaxed tongue and visible bottom teeth.

What is a Canine Play Face?

Dogs have a unique expression called a play face that they display when they're playing with each other.

This play face involves a relaxed open mouth and sometimes you can see a dog's teeth. More commonly, those teeth are visible during some kinds of play called bitey face and jaw sparring.

Dogs often play with their mouths open, their lips retracted, and teeth fully visible. Photographs of the behavior can look quite alarming, but when the action is frozen, you can see the dogs' full sets of teeth, and the lips pulled back enough to see the full form of many of those teeth.

If your dog is displaying a play face, it's likely they're having a good time. However, if your dog growls when you get near their food or toys, it's not necessarily a play face, so be cautious.

A play face is different from a grin, which is a happy, open-mouthed face of a jolly dog. A grin can last for minutes and is often accompanied by a relaxed body language.

Dogs tend to keep their mouths open wide rather than biting down on each other, so even if their teeth are visible, it's likely they're playing and not fighting.

Chemistry Between People

The chemistry between people and dogs is real, and it's backed by science. Oxytocin, often referred to as the "love hormone", plays a significant role in connecting us with our furry friends.

This hormone is released during physical touch and social bonding, which is why we often feel an intense emotional connection with our dogs. I've noticed that when I pet my dog, I feel a sense of calm and relaxation wash over me.

Oxytocin levels surge when we interact with our dogs, strengthening our bond and creating a sense of trust. This hormone is also responsible for the feelings of attachment and affection we experience towards our pets.

As we spend more time with our dogs, our oxytocin levels increase, deepening our emotional connection with them. This is why dog owners often report feeling a strong sense of love and loyalty towards their pets.

Showing your dog affection and praise when they display positive body language, such as wagging their tail, can be a great way to reinforce good behavior. This can help them learn to associate good behavior with positive outcomes.

Rewarding your dog for gentle play can help them understand that rough play is not acceptable. By consistently reinforcing gentle play, you can help your dog develop better social skills.

Reinforcing positive behavior can help your dog feel more confident and secure, leading to a stronger bond between you and your dog.

Smiles happen quickly and are subtle, often lasting only a second. The upward movement of the lips away from the teeth is often slight, making it a challenge to capture them photographically.

Dogs generally show a happy, open-mouthed face when they're relaxed and comfortable in a situation. This facial expression is often referred to as a "grin" or "happy grin."

It's not always easy to tell if your dog is grinning or panting, but paying attention to the context is the best way. If your dog appears to be grinning but they just ran or played hard or it's hot out, they may simply be panting.
