Have you ever observed dogs interacting with one another and noticed them licking each other’s mouths? It’s a curious behavior that may seem strange to us humans. However, there are many reasons why dogs engage in this behavior. In this article, we’ll explore the different reasons why dogs lick each other’s mouths and what it means for their social and emotional well-being.

1. Social Bonding

Dogs are social animals that rely on strong bonds with their pack members to survive. Licking each other’s mouths is a way for dogs to bond with one another and strengthen their social ties. It’s a behavior that is often seen between dogs that have a close relationship with one another, such as littermates or dogs that have grown up together.

When dogs lick each other’s mouths, they are exchanging information about their social status and rank within the pack. This behavior helps to establish a hierarchy within the group and maintain social order.

Additionally, licking each other’s mouths is a way for dogs to show affection and care for one another. It’s a way of saying “I trust you and I care about you”.

2. Greeting Behavior

Dogs use their tongues to gather information about the world around them. When they lick each other’s mouths, they are also gathering information about their pack members. Dogs can learn a lot about each other through their sense of smell and taste.

When dogs meet for the first time, they will often sniff each other’s mouths as a way of greeting. This behavior helps them to gather information about the other dog, such as their age, sex, and health status.

Licking each other’s mouths is also a way for dogs to show submission and respect to one another. It’s a behavior that is often seen in dominant dogs towards their subordinates, as a way of asserting their authority.

3. Play Behavior

Dogs are playful animals that enjoy interacting with one another. Licking each other’s mouths is a behavior that is often seen during playtime, as a way of showing excitement and enthusiasm. It’s a way for dogs to express their joy and happiness in the company of their pack members.

During playtime, dogs may also lick each other’s mouths as a way of teasing and taunting each other. It’s a behavior that is often seen in younger dogs that are still learning how to interact with one another.

4. Medical Reasons

While the majority of mouth licking behavior between dogs is normal and harmless, there are some medical reasons why dogs may lick each other’s mouths. For example, dogs may lick each other’s mouths as a way of cleaning each other’s teeth and gums. This behavior helps to remove food particles and bacteria from the mouth, which can help to prevent dental problems.

However, excessive mouth licking can also be a sign of dental problems or other medical conditions. If you notice that your dog is licking another dog’s mouth excessively, it’s important to have them checked by a veterinarian to rule out any underlying health issues.

5. Final Thoughts

Overall, licking each other’s mouths is a normal and natural behavior for dogs. It’s a way for them to bond with one another, show affection, and gather information about their pack members. While it may seem strange to us humans, it’s an important part of their social and emotional well-being.
