Why Do Dogs Lick & Bite Each Other’s Ears?

Dogs have a way of keeping us guessing, don’t they? One moment, they’re napping peacefully, and the next, they’re licking or nibbling on each other’s ears like it’s the most normal thing in the world. At A Pup Above, we love diving into the fascinating (and sometimes baffling) world of dog behavior to help you understand your pup a little better.

Ear licking and biting might seem odd to us, but for dogs, it’s just another way of communicating. Whether it’s a playful moment, a sign of affection, or something more, we’re here to break it down so you can spot what’s normal and when it’s time to step in.

Why Do Dogs Lick & Bite Each Other’s Ears?

So, why exactly are dogs so fixated on each other’s ears? Turns out, there’s more to it than just curiosity. From social bonding to grooming habits, there are a few reasons behind this quirky behavior. 

Let’s take a closer look:

It’s About Bonding

Dogs use ear licking as a way to strengthen their social connections. It’s their version of saying, “We’re cool, right?” This behavior is especially common in dogs that share a strong bond, like housemates or longtime play buddies. It’s a simple but meaningful way for them to show affection and trust.

They’re Helping Each Other Out

Ears can be tricky to clean, so some dogs take it upon themselves to help their buddies out. Grooming is an instinctual behavior that dogs use to keep their pack healthy. A little lick here and there might just be their way of playing caretaker.

It’s Playtime

Sometimes, ear-biting is just part of a good old-fashioned play session. Dogs communicate through body language, and a gentle nibble can be a way of inviting their friend to wrestle or chase. As long as it’s not too rough, it’s usually all in good fun.

Instincts at Work

Dogs are pack animals, and mutual grooming is a behavior rooted in their wild ancestors. Licking and biting can reinforce their social structure, making them feel secure in their group. Even if it looks odd to us, it’s a natural part of how they interact with their world.

How Should I Manage This Behavior?

If your dog’s ear-licking or nibbling habit seems harmless, you probably don’t need to do much beyond watching them do their thing. But if it’s getting a little over-the-top or causing discomfort, it might be time to step in. 

Here’s how to handle it:

Observe

Start by observing their interactions. If the behavior is gentle and occasional, it’s likely just a sign of bonding or playfulness. But if one dog seems annoyed or tries to pull away or you notice irritation around the ears, you may need to redirect their focus.

Distract and Reward

Offer distractions like toys or engaging activities when the licking or biting becomes too frequent. This is a great way to encourage healthier interactions without scolding them. Positive reinforcement works wonders — reward your dog when they engage in good behavior, so they learn there are better ways to play and bond.

Support Their Health

And don’t forget, what your pup eats can impact their overall health, including their skin and coat. A nutritious, balanced diet like our sous-vide meals helps support healthy skin, which can make those ears less tempting for licking in the first place. Happy dogs, happy ears!

When Does Licking and Biting Become a Problem?

We’ve covered why dogs lick and bite each other’s ears and how to manage it, but when does this quirky behavior cross the line into something you need to worry about? While it’s usually harmless, there are times when ear licking and nibbling can signal a problem.

If the licking becomes excessive — think nonstop attention to the ears — or if you spot any redness, swelling, or an unpleasant smell, it’s time to take a closer look. Overlicking can irritate the skin and even lead to infections, especially in those floppy ears where moisture loves to hang out.

Another red flag? If one dog seems agitated, yelps, or avoids the other, the behavior may be too rough or unwanted. This could strain their relationship or cause injuries.

In some cases, obsessive licking might point to underlying issues like stress, anxiety, or even medical problems like ear mites. If you’re unsure, a quick trip to the vet can rule out anything serious and give you peace of mind. 

Does This Behavior Change with Age?

Like most dog behaviors, ear licking and biting can shift as your pup grows up. Puppies are naturally more curious and playful, so you might notice this behavior popping up a lot when they’re young. For them, it’s a way to explore, bond, and maybe test a few boundaries with their doggy friends.

As dogs mature, the ear obsession usually tones down. Adult dogs tend to lick and nibble less frequently, focusing more on social bonding rather than constant play. That said, some dogs hold onto this habit if it’s part of their relationship with another pup or if it’s become routine.

Senior dogs may slow down even more. Reduced energy, health changes, or mobility issues can mean less interest in behaviors like licking and biting. However, if it continues, it’s usually in a calmer, less playful way.

Age brings changes, but whether they’re a curious pup or a mellow senior, keeping an eye on their interactions is always a good idea. It helps ensure their behavior stays healthy and respectful, no matter their life stage.

How Can You Ensure Your Dog's Ears Stay Healthy?

Keeping tabs on your pup’s ear-licking habits is one thing, but ensuring their ears are truly healthy goes a bit deeper. Just like you wouldn’t skip out on their regular bath time, paying attention to ear care is a key slice of the pet wellness pie. 

Consider these tips to keep those ears in tip-top shape. 

Stay on Top of Cleaning

Just like their furry coats need regular grooming, those ears need consistent check-ins, too. Make cleaning a gentle part of your routine; think of it as a little spa moment for your pup. A soft wipe on the outer ear with vet-approved solutions can keep grime at bay and nip any budding issues in the bud.

Dry Well To Dodge Issues

Water in the ears might sound harmless, but it's party time for bacteria. After any splash session or bath, just take a moment to pat those ears dry. It’s a simple move that could steer you clear of vet visits for infections.

Watch for Worry Signs

Things like odor, redness, or your dog shaking their head more than usual are your cue to act. Early catches help prevent bigger earaches — literally! If something seems off, it’s better to consult your vet sooner rather than later.

Conclusion

So, why do dogs lick and bite each other’s ears? It’s their way of bonding, playing, and sometimes helping out with grooming. While it’s usually harmless, keeping an eye on their behavior and maintaining good ear hygiene can make all the difference in avoiding issues.
