Why does a dog stick out its tongue and lick itself? - briefly
Dogs stick out their tongues and lick themselves primarily for grooming purposes. This behavior helps them maintain cleanliness and hygiene, as well as regulate body temperature by facilitating evaporative cooling.
Why does a dog stick out its tongue and lick itself? - in detail
Dogs stick out their tongues and lick themselves for several reasons, each serving a unique purpose in maintaining their overall well-being.
Firstly, dogs use their tongues as an essential tool for grooming. A dog's tongue is covered with tiny, backward-facing hooks called papillae that help to remove dirt, debris, and loose hair from their fur. This process not only keeps them clean but also aids in temperature regulation by removing excess heat trapped in the coat. Additionally, licking can stimulate blood flow and promote healing, making it an effective way for dogs to tend to minor wounds or irritations on their skin.
Secondly, dogs lick themselves as a means of communication. In the canine world, licking is a sign of submission, respect, or affection. Puppies often lick their mothers' faces as a way to elicit regurgitation, ensuring they receive adequate nutrition. Similarly, adult dogs may lick each other or their human companions to reinforce social bonds and demonstrate their loyalty and devotion.
Moreover, dogs may stick out their tongues and pant as a method of cooling down. When the ambient temperature rises, dogs cannot sweat like humans do; instead, they rely on evaporative cooling through panting. By sticking out their tongues and increasing their respiratory rate, dogs allow heat to dissipate from their bodies more efficiently, helping them maintain a safe internal temperature.
Furthermore, some dogs may exhibit excessive licking behavior as a response to stress or anxiety. If a dog is feeling anxious or bored, it might resort to compulsive licking as a coping mechanism. This can sometimes lead to self-inflicted wounds or skin irritations, requiring intervention from their owners to address the underlying cause of the behavior.
In summary, dogs stick out their tongues and lick themselves for various reasons, including grooming, communication, temperature regulation, and stress relief. Understanding these behaviors can help dog owners provide better care and ensure the well-being of their furry companions.
