Why Do Dogs Lick Other Dogs Mouths

Why Do Dogs Lick Each Other's Mouths? Decoding Canine Communication

Have you ever watched two dogs greet each other with enthusiastic mutual mouth licking? It might seem strange to us humans, but this behavior is actually a complex social interaction with several possible explanations. This article delves into the fascinating world of canine communication to uncover the reasons behind this seemingly unusual habit. Understanding this behavior can offer valuable insight into canine social dynamics and strengthen the bond between humans and their furry friends.

Beyond the Simple Explanation: More Than Just Hygiene

While some might assume it's purely a hygienic act, the truth is much more nuanced. While licking can remove loose food particles or saliva, it's rarely the primary reason. The mouth, for dogs, is a highly sensitive area, and licking carries a wealth of social and communicative information. Let's explore the key reasons behind this behavior:

1. Social Bonding and Affection: The Canine Kiss

Similar to a human kiss, mutual mouth licking often represents a display of affection and trust between dogs, particularly within a pack or family. The act reinforces social bonds and strengthens the hierarchy within the group. Think of it as a canine greeting card: "Hey, I like you, and I'm comfortable with you!" This is especially prevalent among dogs who are already familiar and have established a strong relationship. It's a subtle form of canine bonding.

2. Submissive Behavior and Respect: A Sign of Hierarchy

In certain situations, mouth licking can be a sign of submission or appeasement, particularly from a lower-ranking dog to a higher-ranking one. Licking the dominant dog's mouth can be a way of showing deference and avoiding conflict. This displays respect for the established social order within the canine group. Understanding this can provide useful insight into a dog's position within a social structure.

3. Taste and Scent: Gathering Information

Dogs have an extraordinary sense of smell, and the mouth area contains a wealth of olfactory information. Licking another dog's mouth allows them to gather information about their recent activities, diet, and overall health. This is particularly true for mothers licking their puppies, ensuring their cleanliness and gathering essential information about their young.

4. Stress and Anxiety Relief: Self-Soothing

Just as humans engage in self-soothing behaviors, dogs may lick another dog's mouth as a way to alleviate stress or anxiety. This can be especially noticeable in anxious situations or when dogs are unfamiliar with each other. The act of licking can have a calming effect on the participating dogs.

5. Sharing Resources: A Taste of What's On Offer

In some cases, mutual licking is about sharing resources. If one dog has recently eaten something delicious, another dog might lick its mouth in an attempt to get a taste. This is an opportunistic behaviour, demonstrating that dogs are aware of their environment and seek to benefit from it. It's a straightforward example of resource acquisition.

Conclusion: A Complex Social Act

In conclusion, the seemingly simple act of dogs licking each other's mouths is far from simplistic. It's a multifaceted behavior that serves various social, communicative, and even self-soothing purposes. Understanding these nuances can help us appreciate the complex social lives of our canine companions and improve our ability to interpret their behaviours. So, next time you witness this curious canine interaction, remember that it's likely a display of affection, submission, information gathering, or a combination of these fascinating factors.
