You see dogs licking with their tongues and sticking out their tongues. Besides temperature regulation and emotional expression, dogs keeping out their tongues can also be a sign of stress or illness.

In this article, we will explain why do dogs stick their tongues out and why they are worried about stress and illness. Recognize your dog’s behavior as soon as possible and take appropriate action.

Why Do Dogs Stick Their Tongues Out?

There are several possible reasons why a dog sticks its tongue out:

  • Body Temperature Control
  • Relaxing
  • Excited
  • Feel Stress
  • Calming Signal

Let’s take a closer look at each reason.

Body Temperature Control

Generally, dogs keep their tongues out to regulate their body temperature.

Dogs can’t cool down by sweating like humans. Therefore, they try to lower their body temperature by keeping their tongues out to evaporate saliva. This is a behavior called “punting”, and it is a state of breathing with the tongue.

If your dog sticks out its tongue in hot weather or after exercising, take him to a cool place and give him some water.


Dogs hang their tongues out even when they are calm and relaxed.

From the feeling of comfort and security, the muscles around the mouth relax and the tongue naturally sticks out. The whole body is moderately relaxed, and you can see it when your dog is sleeping or relaxing.


When dogs get excited, they become out of breath and stick out their tongues. They are often seen when they are excited by playing with toys, or when they are excited by physical activity such as exercising or taking a walk.

Calming Signal

A dog may stick its tongue out as a calming signal.

Calming signals are your dog’s emotional signs. When you’re stressed or tense, you stick your tongue out to show that you’re not hostile to others or to those around you.

He also licks his lips to calm himself down. Other behaviors such as licking the nose and yawning can also be seen, all of which are behaviors to distract the mind.

If your dog is sticking out its tongue and giving you a calming signal, let him calm down before you touch him.

Dogs Stick Their Tongues Out (Is It A Syndrome?)

If your dog is sticking its tongue out, it could be due to:

  • Heatstroke
  • Mitral Regurgitation
  • Epilepsy
  • Tracheal Collapse
  • Oral Troubles

If you see any suspicious symptoms, take your pet to the veterinarian.


In hot weather, the risk of heat stroke increases. Dogs can’t regulate their body temperature by sweating, so heat easily builds up in their bodies. Because the temperature control cannot keep up, the tongue may stick out all the time.

Dogs that are close to the ground have a strong reflection of the asphalt, and their body temperature tends to rise. Especially from May to October, it’s easy to get heatstroke, so be careful when walking your dog.

Mitral Regurgitation

Heart disease is among the top two causes of death in dogs. Mitral regurgitation is a disease that is common in small dogs and is caused by abnormalities in the valves inside the heart. In some cases, it can lead to diseases such as heart failure and pulmonary edema, so be careful.

If you are sitting and breathing heavily with your tongue sticking out, trapezius regurgitation is suspected.


Dog stick their tongues out because of severe health condition such as epilepsy. Early symptoms of epileptic seizures are tongue sticking and lip licking. If you see this kind of behavior, keep an eye on your dog.

Tracheal collapse

Tracheal collapse occurs when the trachea is crushed and lacks oxygen, and symptoms include sticking out the tongue and frequent coughing.

It is common in senior dogs, obese dogs, and children who lack exercise, and breeds such as pugs, Yorkshire terriers, and Maltese are susceptible to it.

Oral Trouble

Malocclusion, teeth alignment, stomatitis, oral tumors, gum inflammation, tooth loss, and other oral problems can cause the tongue to protrude.

If your dog has a malocclusion or misaligned teeth, it is difficult to correct it like a human being, so you will have to live while watching the situation.

Senior dogs are prone to periodontal disease, and it is not uncommon for them to have their tongues out naturally due to tooth loss.

If there is a possibility of damaging the inside of the mouth, treatment such as tooth extraction under general anesthesia may be performed, but it depends on the judgment of the veterinarian.


Why do dogs stick their tongues out? It can be for a variety of reasons, including functional aspects such as thermoregulation, and emotions such as excitement, relaxation, and calming signals.

However, sticking out the tongue can cause stress and illness, so it is necessary to carefully observe the dog’s appearance, behavior, and situation, and respond accordingly.

By catching the signs given by your dog without missing them, you can quickly notice any abnormalities. Let’s take care of our dogs on a daily basis and support them so that they can live a healthy life.
