🐶 Dog MysteryThe short answer
Ear-licking is social grooming and affection (dogs groom packmates’ ears), plus they’re drawn to the scent and taste of earwax. It’s usually bonding — but obsessive licking of another pet’s ears can hint at an infection.
Ear-licking is one of the more specific dog behaviours, and unusually it has an answer that is partly social and partly just chemistry. Ears are a genuinely rich target, and dogs are not being random when they go for them.
Ears smell interesting
The ear canal produces cerumen — earwax — which is a mix of secretions, shed skin cells and oils. It carries a concentrated scent signature, and it is warm and slightly salty. For an animal whose primary sense is smell, an ear is one of the most information-dense parts of a person that is also physically reachable.
This is why ear-licking often intensifies when you are lying down or sitting low. Access is the limiting factor, not interest.
The social explanation
Between dogs, mutual grooming concentrates on the head and neck — precisely the areas an individual cannot reach on itself. Ear-licking between dogs that live together is common and is an affiliative behaviour: it appears between animals with an established relationship rather than between strangers.
A dog licking your ears is applying that same social grooming pattern to you. It is the canine version of including you in the group, and it usually indicates comfort rather than anything more complicated.
Face and head licking also carries the appeasement thread found throughout dog licking — a deferent, tension-reducing signal. In a dog that is generally confident and relaxed, that reading is less likely than the grooming one.
The part worth acting on
Here is the practical value in this article: if a dog is fixated on licking another dog's ears, that dog frequently has an ear problem. Dogs are drawn to infection — the smell changes, and discharge is attractive to them.
The same logic applies in reverse to your dog's own ears. A dog that scratches at its ears, shakes its head repeatedly, rubs its head along furniture, or lets another dog lick its ears persistently should have those ears examined. Otitis externa is extremely common, frequently secondary to allergies, and it is painful.
If two dogs live together, check the licked one
Persistent ear-licking between dogs is one of the more reliable informal indicators of ear disease in the recipient. Look for redness inside the ear flap, a yeasty or sour smell, brown or black discharge, head-shaking or head-tilting, or sensitivity when the ear base is touched. Ear infections rarely resolve alone and are uncomfortable enough that they are worth catching early.
Hygiene, specifically for ears
This one deserves a bit more care than hand-licking. The ear canal is a warm, moist environment adjacent to a mucous membrane, and introducing saliva is not ideal.
- Do not let a dog lick inside the ear canal. Around the outer ear is lower risk; inside it is not advisable.
- Avoid entirely if you have a perforated eardrum, grommets, an existing ear infection, or have had recent ear surgery.
- Be cautious if you are immunosuppressed, pregnant or elderly — dog saliva carries bacteria including Capnocytophaga, uncommon but potentially serious in those groups.
- Wash the area afterwards, and keep your dog's parasite prevention current.
If you develop ear pain, itching, discharge or reduced hearing after repeated licking, see a doctor and mention the exposure — it is relevant history and worth stating plainly rather than leaving out.
If you want it to stop
Ear-licking is usually easy to manage because it is opportunistic. Sitting up, turning your head, or standing removes access. Do not push the dog's face away — it is contact, and many dogs read it as play, which reinforces the behaviour you are trying to reduce.
Redirect instead: move away, then immediately reward something incompatible, such as settling on a mat or a chew. As with any attention-maintained behaviour, consistency across the household matters more than the specific technique.
When to involve a vet
Have your dog's ears checked if it shakes its head, scratches at its ears, tilts its head, rubs its head on furniture, or if there is redness, discharge or a strong smell — these signs together with another dog licking its ears strongly suggest infection. Separately, book an appointment if your dog's licking of you has become obsessive, hard to interrupt, or has spread to floors and furniture, which points toward anxiety or a gastrointestinal cause rather than social behaviour.

Frequently asked
Why does my dog lick my ears?
Earwax carries a concentrated scent signature and is warm and slightly salty, making ears an information-dense target for an animal led by smell. It also mirrors social grooming between dogs, which concentrates on the head and neck — areas an individual cannot reach alone.
Does ear licking mean my dog is bonded to me?
Generally yes. Between dogs, head and neck grooming appears between animals with established relationships rather than strangers, so a dog applying it to you is treating you as part of its group.
Why does my dog lick my other dog's ears?
Often because that dog has an ear problem. Infection changes the smell and produces discharge that dogs find attractive. Persistent ear-licking between dogs is a reliable informal sign that the recipient's ears should be checked.
Is it safe to let my dog lick my ears?
Less advisable than hands. Do not allow licking inside the ear canal, and avoid it entirely with a perforated eardrum, grommets, an existing infection or recent ear surgery. Be cautious if immunosuppressed, pregnant or elderly.
How do I stop my dog licking my ears?
It is opportunistic, so removing access usually works — sit up, turn your head, or stand. Do not push the dog's face away, as many dogs read that as play. Redirect and reward an alternative such as settling on a mat.
What are the signs my dog has an ear infection?
Head-shaking, scratching at the ears, head-tilting, rubbing the head on furniture, redness inside the ear flap, brown or black discharge, a yeasty or sour smell, and sensitivity when the ear base is touched. Ear infections rarely resolve on their own.
