When we observe the behavior of dogs in winter, we may notice an interesting phenomenon: even in cold weather, dogs will stick out their tongues from time to time. Many people think it's the dog losing heat, but that's not the case. So why do dogs stick out their tongues in winter?

To begin with, we need to understand how dogs regulate their body temperature. Unlike humans, dogs can't sweat to dissipate heat, so they need to rely on other methods to regulate their body temperature. When dogs breathe, they take in cold air through their mouth and nose, which allows them to sense the ambient temperature around them by breathing. When dogs exhale, they take away the heat by evaporating water from their tongues, thus keeping their body temperature stable.

Besides, the canine's tongue is additionally a significant organ for its intensity dissemination. Canines have a ton of veins and sweat organs on their tongues, and when they let out their tongues, these veins and perspire organs extend, which assists the canine with disseminating overabundance heat. Particularly in winter, when the temperature is low, canines accelerate their breathing rate by standing out their tongues to advance intensity scattering.

Additionally, dogs can stick out their tongues because they are enjoying a certain feeling or experience. For example, when dogs are enjoying being petted or played by their owners, they may stick out their tongues to signal their pleasure and relaxation. Or, when dogs are sniffing the scent of interest, they also stick out their tongues to gather more information.

It should be noted that if the dog frequently sticks out his tongue in winter and is accompanied by other symptoms, such as respiratory difficulties, cough, fever, etc., it is recommended to take them to the vet for check in time. This could be a sign that the dog has a respiratory disease or other health problem.

In a nutshell, canines stick out their tongues in winter to manage internal heat level and express feelings. By understanding the purposes for this peculiarity, we can more readily figure out the way of behaving and needs of canines and furnish them with better consideration and backing.
