Why Does My Younger Dog Clean My Older Dog? Explained

If you’re a dog owner, you may have observed an intriguing behavior where your younger dog occasionally engages in grooming and cleaning rituals directed towards your older dog. 

This seemingly odd conduct can leave you wondering about the reasons behind it. In this article, we will delve into the fascinating world of canine behavior to understand why your younger dog might feel compelled to clean and groom its senior companion. 

We will explore the biological, social, and emotional aspects that underlie this behavior while shedding light on the significance of grooming in canine communication. 

Let’s explore this intriguing canine phenomenon and gain insights into the intricate world of dogs’ social dynamics.

Understanding Canine Grooming Behavior

Grooming is an innate behavior in dogs, stemming from their ancestral roots as pack animals. Wolves, the ancestors of domestic dogs, engage in grooming as a means of establishing and maintaining social bonds within the pack. 

This grooming behavior served as a form of communication, reinforcing social hierarchy and demonstrating respect and submission to higher-ranking members of the pack.

The Role of Instinct and Pack Dynamics

Despite the domestication process, dogs have retained many of their ancestral instincts, including grooming. 

When a younger dog grooms an older dog, it is reminiscent of the pack structure in the wild, where the younger and more subordinate wolves demonstrate their respect for the pack’s older and higher-ranking members. This behavior is hardwired into their genetic makeup, passed down through generations.

Showing Respect and Submission

In the domestic setting, this grooming behavior often carries over to multi-dog households. When a younger dog cleans an older dog, it is a display of respect and submission. 

The younger dog recognizes the seniority and authority of the older dog and acknowledges its higher rank in the household hierarchy.

Establishing Social Bonds

Grooming is not merely a display of submission but also serves to build and strengthen social bonds among dogs. In a canine household, grooming is a social activity that fosters a sense of community and belonging. 

When your younger dog grooms your older dog, it’s a way for them to forge a stronger bond, which can help reduce tension and conflicts within the pack.

Stress Reduction and Comfort

Grooming is known to release endorphins, which induce feelings of pleasure and comfort. When your younger dog cleans your older dog, it can serve as a stress-relieving activity for both dogs. 

For the younger dog, grooming an older companion might be soothing and comforting, especially during times of anxiety or uncertainty.

Maintaining Pack Cohesion

Grooming also plays a role in maintaining the cleanliness and hygiene of the pack. In the wild, a clean and well-groomed pack is less likely to attract predators and maintain a healthier environment. 

This instinctual need for cleanliness is present in domestic dogs as well, and when your younger dog cleans your older dog, it could be fulfilling this role, ensuring the overall hygiene and well-being of the pack.

Emotional Bond and Affection

Grooming is an intimate act, and when your younger dog cleans your older dog, it demonstrates a deep emotional bond and affection between the two.

Excessive grooming could be a sign of underlying stress, anxiety, or even a medical condition that requires attention from a veterinarian.


The behavior of a younger dog cleaning an older dog is a testament to the intricate world of canine communication and social dynamics.
