Why Do Dogs Stick Their Tongue Out?

1. They feel relaxed


They feel relaxed


The good news is when you see a dog sticking its tongue out, it often means they are relaxing.

For example, if they had a good meal, played a lot, or just lay next to you and stuck out their tongue, this could be a sign that they feel happy and calm. They may even appear smiling, as dogs use their faces to express their feelings, just like humans. 


2. They're panting


They’re panting


Dogs stick their tongues out because they're panting, and you might notice your dog doing this when they get warm. When dogs get hot, they can't sweat like humans, so they pant instead. This panting is similar to how we sweat because it helps cool their bodies through evaporation.

Breathing quickly helps water evaporate from their tongue and upper respiratory tract, which cools them down. 


3. They are cooling down


They’re cooling down


Dogs will stick out their tongues, especially when the weather is hot. They do this to cool down because, unlike humans who sweat, dogs cannot sweat like us. Instead, they pant to help release saliva from their tongues, which cools them down.

So, to help them cool down, make sure they're in a cool place, let them rest, and give them plenty of clean water to drink.


4. Hanging tongue syndrome


Hanging Tongue Syndrome


Hanging tongue syndrome is when a dog's tongue hangs out of the mouth. Don't worry, this isn't a sign of any other trouble.


Due to genetic reasons, this condition is more common in smaller and brachycephalic breeds, such as pugs. Sometimes, their tongue is too big for their mouth, or their breeding may have caused jaw abnormalities that prevent them from supporting it. Dogs with an overbite or underbite may also develop this condition, especially as they age.


5. Oral cancer and lumps


Oral cancers and masses


Oral cancer and lumps can affect the placement of your dog’s tongue. Unfortunately, most of these tumors are malignant. However, small bumps called papillomatosis can also appear on the tongue, which are usually benign and caused by the papillomavirus.

In both cases, these growths take up a lot of space in the mouth, causing the dog to stick out its tongue.


6. They started a new medication


They started a new medication


New medications can sometimes cause side effects in dogs, one of which is tongue sticking out. This symptom is usually temporary and goes away on its own after a few days.

However, if your dog seems uncomfortable or symptoms persist, be sure to consult your veterinarian.
