Why Does My Dog Nibble On My Other Dog? Understanding Canine Behavior

Observing their pets interact is both a joy and a curiosity for many dog owners. One behavior that often catches the eye (and may raise an eyebrow or two) is when one dog starts to nibble or ‘mouth’ another dog. What exactly is happening here? Is it a sign of affection, dominance, or quirky behavior?

If you’re in this perplexed group of pet parents, fret not. We’re diving deep into this topic to clarify the age-old question: “Why does my dog nibble on my other dog?”

Why Does My Dog Nibble On My Other Dog?

1. Affection and Bonding:

One of the most common interpretations of this behavior is that it signifies affection. Dogs, similar to humans, have their ways of expressing love and attachment. Grooming is one of them. In the wild, wolves and other wild canids often groom each other to strengthen social bonds. Nibbling can sometimes be an extension of this grooming behavior. By nibbling or mouthing, dogs may be trying to clean an area their fellow dog can’t reach or showcasing a sign of love.

2. Play Behavior:

Dogs, especially puppies, are known for their playful nature. Sometimes, this playful behavior manifests as gentle biting or nibbling. This is not aggressive but simply a part of their play routine. Dogs often use their mouths to explore their surroundings and engage with their peers. If both dogs seem relaxed and wag their tails, it indicates that the nibbling is all in good fun.

3. Exploratory Behavior:

Dogs explore the world primarily with their noses and mouths. Nibbling can be an exploratory behavior where they try to learn more about their environment or even their fellow canine companion. It’s not unusual for a new dog in the household to nibble on an older dog, as they’re getting to know them better and understanding their place in the pack.

4. Display of Dominance:

While many instances of nibbling are harmless, it can sometimes be a subtle display of dominance. If one dog consistently nibbles another, always on the same spot as the ears or neck, it might be trying to assert its position in the hierarchy. Monitoring these interactions to ensure they don’t escalate into more aggressive behaviors is essential.

5. Behavioral Issues or Compulsions:

Sometimes, nibbling can be a sign of behavioral issues or compulsive actions. If your dog constantly nibbles on your other dog, objects, or itself, it might be dealing with anxiety, boredom, or other underlying problem. In such cases, consulting with a veterinarian or a canine behaviorist is crucial.

6. Seeking Attention:

Your dog might have noticed that it grabs your attention when it nibbles on its fellow furry mate. Dogs are intelligent beings, and if they associate behavior with getting noticed, they might repeat it.

7. Health Concerns:

There are instances where one dog might nibble another due to a health issue. The dog being nibbled on might have a wound, infection, or some residue on its fur that the other dog is trying to get to. Inspecting the nibbled area is always a good idea to ensure no health concerns.


While the sight of your dog nibbling on its buddy might seem odd, it’s usually a benign behavior that arises from affection, playfulness, or exploration. However, as a responsible pet owner, it’s essential to be vigilant and ensure this behavior doesn’t cross into dominance or aggression. Monitoring their interactions, understanding the context, and recognizing the body language of both dogs will offer insights into their relationship.

If the nibbling becomes persistent, aggressive, or you notice any signs of distress in either of the dogs, it’s advisable to consult with a pet professional. They can guide your dogs’ needs and ensure a harmonious household for everyone involved.
