Why Does My Dog Bite Her Puppies’ Heads? Explained

Welcoming a litter of adorable puppies into the world is an exciting experience for any dog owner. However, it’s not uncommon to witness a mother dog gently biting the heads of her newborn puppies. 

This behavior can be concerning and confusing for pet parents, but it is usually a natural instinct rooted in the complex world of canine maternal behavior. 

In this article, we will delve into the reasons why a dog might exhibit this behavior and shed light on its significance in nurturing her offspring.

Establishing Maternal Bonds

A dog biting her puppies’ heads, known as “picking up,” is a critical part of maternal bonding. Through this behavior, the mother establishes her authority and communicates her role as the caregiver. 

By picking up her puppies, she helps them understand their place in the litter hierarchy while asserting her position as the leader.

Stimulation and Cleaning

Another primary reason for a mother dog biting her puppies’ heads is to stimulate them. Newborn puppies are born with limited sensory abilities, and their bodily functions are not yet fully developed. 

By gently biting their heads, the mother encourages them to urinate and defecate, aiding in the elimination process. Additionally, this behavior also serves as a form of cleaning, as the mother licks and nibbles the puppies to keep them clean and free of debris.

Teaching Boundaries and Disciplining

A mother dog biting her puppies’ heads can also be a way to teach them boundaries and discipline. Puppies, like human infants, are curious and exploratory.

Through gentle corrections, the mother dog teaches them the limits of acceptable behavior within the litter. By biting their heads, she communicates when they have crossed a line or become too rough during playtime. 

This helps puppies develop social skills and understand how to interact appropriately with their siblings.

Encouraging Independence

As the puppies grow, the mother dog gradually encourages their independence. Biting their heads is one way she nudges them toward self-reliance. 

By doing so, she urges them to explore their surroundings, interact with their littermates, and begin to rely less on her constant care. This gradual process is crucial for the puppies’ development, as it prepares them for their future lives outside the litter.

Alleviating Stress and Anxiety

Mother dogs, like any new parents, can experience stress and anxiety. Biting their puppies’ heads can serve as a stress-relief mechanism for them. 

The rhythmic nibbling may help the mother alleviate her own anxiety, providing her with a sense of comfort and relaxation during the demanding period of nursing and caring for her young.

Abnormal Behavior

While biting the heads of puppies is generally a normal part of canine maternal behavior, there are instances when it may indicate underlying issues. 

If the mother dog displays excessively rough or aggressive behavior towards her offspring, it could be a sign of maternal aggression or poor socialization. 

In such cases, it is essential to seek guidance from a professional veterinarian or animal behaviorist to address the issue and ensure the well-being of both the mother and her puppies.


The sight of a mother dog biting her puppies’ heads may initially cause concern for dog owners, but understanding the reasons behind this behavior can help alleviate worries.

From establishing maternal bonds to stimulating, cleaning, and teaching boundaries, a mother dog’s gentle nibbling serves several vital purposes in the development of her puppies. 

While monitoring their interactions is important, it is crucial to remember that most canine mothers instinctively know how to care for their offspring. 

However, if any concerns arise or the behavior appears abnormal, consulting with a veterinary professional is always recommended. 

By appreciating the complexity of maternal behavior in dogs, we can better support and understand these remarkable creatures as they navigate the joys and challenges of motherhood.
