Why Do Dogs Lick Each Other's Mouths?
If you've ever watched a group of dogs interact, you've probably noticed one dog licking another's mouth. This seemingly simple behavior carries a lot of meaning in the canine world. Let's explore why dogs do this and what it means for their relationships.
Social Communication Among Dogs
Dogs are highly social animals. They rely on body language and physical gestures to communicate with each other. Licking another dog's mouth is one such gesture that serves several purposes in their complex social structure.
- Submission: A younger or more submissive dog might lick the mouth of an older or more dominant dog to signal respect or deference.
- Affection: Sometimes, dogs lick each other's mouths simply as a friendly greeting or to show affection, much like how humans might hug or shake hands.
- Appeasement: If a dog senses tension, licking can be a calming signal meant to diffuse potential conflict.
Puppy Behavior and Instincts
This behavior actually starts when dogs are puppies. In wild canines (and sometimes domestic ones), puppies lick their mother's mouth to encourage her to regurgitate food for them. This instinctual action often carries over into adulthood, even though regurgitation isn't involved anymore.
- Puppies approach adult dogs and lick their mouths as a way of seeking attention or food.
- This behavior is generally tolerated by adult dogs, reinforcing social bonds within the group.
The Role of Scent and Taste
A dog's sense of smell is extraordinary. By licking another dog's mouth, one dog can gather information about what the other has eaten or where they've been. It's like reading a story told by scents and tastes—dogs learn about each other's recent activities through this intimate form of investigation.
Licking as Play and Bonding
Licking isn't always about hierarchy or information gathering; sometimes it's just fun! During playtime, dogs may lick each other's faces and mouths as part of their joyful interaction. This helps strengthen friendships and maintain harmony within the pack (or household).
- Licking can interrupt rough play before it escalates.
- It reinforces trust between canine companions.
When Is Mouth Licking a Concern?
Most of the time, this behavior is perfectly normal and healthy. However, if you notice excessive licking, signs of discomfort from the licked dog, or any wounds in the mouth area, it could indicate stress or health issues that need attention. Always watch for changes in your dog's typical social behaviors.
What Should Owners Do?
If your dogs are licking each other's mouths during greetings or playtime—and both seem relaxed—there's no need to intervene. It's part of how they connect with one another. If you're introducing new dogs, pay attention to these signals: gentle licking can mean things are going well!
- If either dog seems anxious or aggressive, separate them calmly.
- If licking becomes obsessive or leads to irritation, consult your veterinarian or an animal behaviorist.
The Takeaway
Mouth licking among dogs is rooted in instinct and serves many positive functions: communication, bonding, learning about each other, and maintaining peace within the group. When you see your pups exchanging licks around the mouth, they're likely just being good friends—or showing respect in their own unique way!
