Why Do My Dogs Lick Each Others Ears

The other morning, I woke up to a sound like a tiny, wet motorboat. My golden retriever, Gus, had his head locked onto the ear of my lab mix, Lily, who was standing perfectly still with a look of pure, blissful stupor. I just froze, coffee in hand, wondering if I had accidentally stumbled into some sort of canine spa ritual.

If you have ever seen this happen in your own home, you know exactly what I mean. It is equal parts adorable and deeply, deeply confusing. Why do they do this? Is it love? Is it a hygiene check? Or have my dogs secretly formed a pack dedicated to listening to the world’s most boring podcast?

The Great Ear-Cleaning Conspiracy

Let us get the most obvious reason out of the way first: cleanliness. Dogs are not exactly known for their use of Q-tips, but they are geniuses at using their tongues as washcloths.

Your dog might be licking their buddy’s ear because they sense some wax, dirt, or a weird smell. It is a deeply ingrained grooming instinct. Think of it as a favor: “Hey, you missed a spot back here, pal.”

But here is the ironic twist. Too much of this “help” can actually cause ear infections. So your dog, in their infinite wisdom, might be spreading moisture right into a dark, warm cave—perfect for yeast parties. Nice going, Fido.

The Flavor Factor (Yes, Really)

Be honest for a second: earwax is gross to us, but to a dog, it smells like fine cuisine. Dog earwax contains dead skin cells, oils, and a ton of pheromones—basically a biological resume of who that dog is.

When your dog licks another dog’s ear, they are essentially reading a tiny, salty ID card. “Ah, yes, you are the one who stole my bone yesterday. I taste your guilt.” It is weird, but so is loving someone who eats their own vomit. We don't judge around here.

So yes, sometimes the answer is simply: it tastes good. If that makes you uncomfortable, just remember what they lick when you are not looking. Ears are probably the highlight of their day.

The Submissive Signal

Dog body language is a soap opera of tiny gestures. If you watch closely, the dog getting licked often lowers their head or exposes their neck. That is a classic sign of submission or trust.

By licking the ear, the other dog is saying, “I am not a threat. I am just checking your vibe, bro.” It is a peace offering. It is the canine equivalent of bringing someone a cup of tea and saying, “Tell me about your day.”

This happens a lot in multi-dog households where one dog is clearly the boss. The boss dog holds still while the other one grooms them. It reinforces the pack hierarchy without a single growl. Pretty smart, right?

Boredom and Comfort (The Netflix Effect)

Let us not overthink this too much. Sometimes, a dog licks another dog’s ear because there is literally nothing else to do. You are on your laptop, the squirrels are hiding, and the TV is playing a documentary about glaciers. The ear is just… there.

Licking releases endorphins in dogs. It calms them down. It is their version of popping a bubble wrap or chewing gum nervously. If your dogs do it while settling down for a nap, they are just self-soothing together.

And honestly? It is kind of sweet. They are basically saying, “You are my favorite pillow, and I will groom you until we both fall asleep.” Romantic, if you ignore the slobber.

When Should You Worry?

Okay, I have been pretty chill about this, but let me be serious for a second. Not all ear-licking is harmless. If one dog is absolutely obsessed—licking for hours, following the other dog around just to get a taste—something might be up.

Check the ear being licked. Is it red? Does it smell like corn chips or yeast? Is the dog shaking their head a lot? That could be an infection. Your dog might be trying to “fix” a problem that actually requires a vet. You know, like a well-meaning friend who puts a band-aid on a broken leg.

Also, if the dog being licked is trying to escape, growling, or hiding, you need to step in. One dog’s spa day is another dog’s nightmare.

The Final Slobber

So why do dogs lick each other’s ears? The answer is a messy cocktail of hygiene, flavor, submission, comfort, and pure boredom. It is a ritual that makes no sense to us but perfect sense to them.

The next time you catch them at it, just shrug. Take a picture. Or, if you are brave, lean in and ask them: “Is it worth the earwax?” They won’t answer, of course. They will just look at you with those big, innocent eyes, tongues still wet, and judge you for interrupting their very important business.
