This article will delve into the reasons why dogs lick each other’s mouths, touching on the differences between submission and affection. We’ll also explore the various scenarios in which dogs may lick each other’s tongues and what these actions signify.

Finally, we’ll go over whether it’s necessary to stop them when dogs lick each other’s mouths and explain how to manage this behavior if needed. Let’s begin!

Why Do Dogs Lick Each Other’s Mouths?

Why Do Dogs Lick Each Other's Mouths?

Dogs lick each other’s mouths for several reasons, including communication, showing affection, or as a submissive gesture. This behavior originates from their wolf ancestors, where puppies would lick the mouths of adult dogs to stimulate regurgitation of food. In modern dogs, this behavior has evolved to include expressions of friendship, respect, or as a way to solicit attention or food from their human companions or other dogs.

Why Do Dogs Lick Each Other in the Mouth?

Dogs lick each other in the mouth as a form of social interaction. It can be a sign of affection, a greeting, or a submissive behavior. This action helps to strengthen the bond between dogs and establish their social hierarchy within a group. It’s a natural behavior that serves various purposes in canine communication.

Dogs Licking Each Other’s Mouths: Submission vs. Affection

To determine whether dogs are licking each other’s mouths out of submission or affection, observe their body language:

  • Submission: A submissive dog may approach another dog with a lowered posture, ears back, and possibly averted eyes. The licking is often quick and directed towards the more dominant dog’s mouth.
  • Affection: When licking is a sign of affection, both dogs usually appear relaxed. Their bodies are loose, tails may wag gently, and the licking is reciprocal rather than one-sided.

Should I Stop Dogs Licking Each Other’s Mouths?

Generally, you should not need to stop dogs from licking each other’s mouths unless it leads to signs of discomfort or aggression from one of the dogs. If intervention is necessary:

  • Distract the dogs with a command, toy, or treat to redirect their attention.
  • Separate the dogs gently if one appears to be stressed or overwhelmed by the licking.

Dogs licking each other’s mouths is a natural behavior with various meanings, including affection and submission.

Watching the dogs’ body language and following these steps will help keep these interactions playful, but it’s important to remember that any underlying behavioral issues (dominance, aggression, etc.) that may be causing any problems in this area will still be present.

And until you address those, any positive changes you see will only be temporary.
