Why Do Dogs Keep Sticking Out Their Tongues?

Anyone who has raised a dog knows that dogs don’t have sweat glands, so sticking out their tongue is an essential way for them to cool down. Pet owners can also observe their dog’s health by paying attention to the frequency and manner in which they stick out their tongues during grooming sessions.

However, dogs don’t only stick out their tongues when it’s hot. Pet owners may notice that dogs often stick out their tongues even when the weather is normal or during the winter. There are several reasons for this: Temperature Regulation: Dogs need to maintain a constant body temperature, and sticking out their tongue helps with this process. Grooming, which removes excess fur, can also lighten their load and help them regulate temperature better. Emotional States: When dogs are nervous or excited, they may stick out their tongues as a way to calm themselves down. Happiness or Comfort: If a dog feels relaxed or comfortable—perhaps after a pleasant grooming session or gentle petting—they might stick out their tongue and “smile” at their owner. This is often seen in the familiar smiling Shiba Inu meme. Thirst: Sometimes, a dog simply sticks out its tongue because it’s thirsty and wants a drink of water. In addition to sticking out their tongues, a dog’s paw pads are also important for temperature regulation. Especially as temperatures rise, owners should regularly groom their dog’s paw pads and trim their nails to help them cool down more efficiently. Most dogs have thick fur, and even with daily grooming, there might still be areas that are overlooked. If a dog starts breathing rapidly, sticks out its tongue excessively, or appears lethargic, it could be a sign of overheating. If, after grooming, you notice that your dog has fallen asleep with its tongue sticking out, don’t be alarmed—it just means they’re sleeping soundly, and they might even drool a little. In conclusion, the primary role of a dog’s tongue is to help cool them down. A normal dog’s body temperature should range from 37.8°C to 39°C. If the temperature rises too high, it could lead to heatstroke or internal organ dysfunction. As summer approaches, pet owners should pay extra attention to regular grooming and monitoring to ensure their dog stays healthy and comfortable.
