5 Common Reasons Dogs Lick Other Dogs’ Privates

The curious and often mystifying behavior of dogs is a subject of much intrigue and debate. One behavior that has long puzzled and fascinated dog owners and animal experts alike is the tendency of some dogs to engage in genital licking, not just on themselves, but also on other dogs. While this behavior may seem taboo and bizarre to humans, it is a common occurrence in the animal kingdom and is shrouded in a veil of mystery and complexity.

Delving into the underlying reasons for this behavior requires an exploration of the intricate and nuanced social dynamics, biological factors, and instinctual drives that shape the behavior of our furry companions. So, why do dogs lick each other’s privates, and what does it reveal about their inner workings?

Dogs may lick other dogs’ genital areas for various reasons, including:

  1. Social behavior
  2. Exploration
  3. Dominance
  4. Medical issues
  5. Sexual behavior

Let’s dive into it.

Social behavior

Dogs, like many social animals, have a complex and nuanced system of communication that includes body language, vocalizations, and even touch. One of the most common forms of touch communication among dogs is licking, which can serve a variety of purposes. Dogs may use licking as a way to communicate emotions such as affection, respect, or submission, and it can also be a way to establish and maintain social bonds within a pack or group.

When it comes to genital licking, there are several possible reasons why dogs may engage in this behavior as a form of social interaction. For example, some dogs may lick each other’s genital areas as a way of greeting or showing affection. This may seem strange to us humans, but to dogs, it’s a natural and instinctual behavior that helps them establish and maintain social connections with one another.

Another possible explanation for genital licking as a social behavior is that it can serve as a way for dogs to exchange information about one another. Dogs have an incredibly keen sense of smell, and licking is one way they can gather and analyze scent information from other dogs. By licking another dog’s genital area, a dog can learn about the other dog’s diet, health, and reproductive status, among other things. This information can be useful for establishing and maintaining social hierarchies, as well as for choosing potential mates.

Dogs have an incredible sense of smell that they use to explore and learn about the world around them. In fact, their sense of smell is so keen that it can detect even the slightest changes in scent and can even be used to detect certain diseases in humans. Along with their sense of smell, dogs also have an innate sense of taste, and licking is one way that they can use both senses to investigate and analyze their environment.

When it comes to genital licking, it’s possible that dogs may engage in this behavior out of curiosity or to investigate a new scent. Dogs are naturally curious creatures, and they use their senses to explore and learn about their surroundings. By licking another dog’s genital area, they can gather valuable scent information that can help them better understand and navigate their environment.


Canine social dynamics are complex and intricate, with dominance and hierarchy playing a crucial role in shaping group interactions. As such, dogs use a variety of behaviors to assert their dominance over one another, and licking can be one such behavior. In some cases, a dog may lick another dog’s genital area as a way of asserting its dominance or establishing its place in the social hierarchy.

This behavior is often seen in packs of dogs where there is a clear leader and followers. The dominant dog may lick the genital area of a subordinate as a way of demonstrating its authority and control. Additionally, this behavior can be used to reinforce social bonds between dogs, as the act of licking can release endorphins and create a sense of closeness and intimacy between dogs.

In the end, the reasons why dogs lick each other’s genital areas are multifaceted and complex, with a range of factors, including social dynamics, biology, and individual differences, all playing a role. By continuing to study and better understand these behaviors, we can gain a greater appreciation for the intricacies and nuances of canine social life.

Medical issues

A range of medical issues can cause dogs to lick their own or other dogs’ genital areas excessively. For example, a urinary tract infection (UTI) can cause dogs to feel discomfort or pain while urinating, and they may attempt to relieve this discomfort by licking the area. Additionally, skin irritation or an allergy can cause itchiness and discomfort in the genital area, leading dogs to lick the area in an attempt to soothe the irritation.

Sexual behavior

In some cases, dogs may lick each other’s genital area as part of sexual behavior. This can be more common between male and female dogs during mating, where the act of licking may serve as a way of stimulating the genitals and increasing the chances of successful mating.


The subject of dogs licking other dogs’ genital areas is multifaceted, and there are a variety of reasons why this behavior may occur. Some reasons may include social behavior, exploration, dominance, medical issues, and sexual behavior. It’s important to recognize that dogs may lick each other’s genital areas for reasons other than sexual behavior, and it may be a form of communication, investigation, or a sign of an underlying medical issue. Understanding the possible reasons for this behavior can aid in interpreting canine behavior and provide insight into their needs and health.
