How to Check Your Dog's Ears [What Healthy Ears Look Like]
A healthy dog ear is pale pink inside, smells of almost nothing, and has little or no wax. To check it, lift the flap in good light, look at the skin and the canal opening, smell, and compare both ears. Redness, swelling, a yeasty or foul smell, dark or yellow discharge, head shaking, and pain on touch are reasons to see a vet. Never push cotton swabs into the canal, and photograph each ear so you can compare week to week.
Your dog has been shaking his head more than usual, or scratching at one ear, or you simply want to stay ahead of problems. A quick look inside the ears once a week is easy to do and catches most trouble while it is still minor. Here is how to do it properly.
Why weekly checks are worth it
A dog's ear canal is shaped like an L. It drops vertically from the opening and then turns toward the eardrum. That design protects the eardrum but also traps warmth and moisture, which is exactly what yeast and bacteria like. By the time a dog is obviously uncomfortable, an infection has usually been building for a while.
Dogs with floppy ears, hairy ear canals, allergies, or a love of swimming are more prone to ear problems and benefit most from a routine. But every dog can develop an infection, a foreign body, or mites.
What a healthy ear looks like
- Skin inside the flap and at the canal opening is pale pink, not red.
- Little or no visible wax; a thin light-brown film is normal for some dogs.
- No strong smell. A faint waxy scent is fine; a sweet, yeasty, or foul odor is not.
- No swelling, scabs, or crusts on the flap or at the opening.
- The dog does not flinch or pull away when you handle the ear.
Learn what your own dog's normal looks like. Some breeds have naturally darker skin or more wax, and the goal is to notice change from that baseline.
Healthy ear or vet visit: a quick comparison
| Check | Healthy | Ask a vet |
|---|---|---|
| Color | Pale pink, or the dog’s usual pigment | Red, dark pink, or hot to the touch |
| Smell | Almost none, faintly waxy | Sweet, yeasty, sour or foul |
| Wax and debris | None or a thin light-brown film | Dark brown crumbly debris, yellow or green discharge |
| Skin | Smooth, no scabs | Swelling, crusts, scabs, thickened skin |
| Behavior | Relaxed when touched | Head shaking, scratching, head tilt, pulling away in pain |
Step-by-step check
- Pick a calm moment. After a walk, when the dog is relaxed. Have a treat ready. For the first few checks, keep it short and pleasant so the dog learns there is nothing to fear.
- Get good light. Sit near a window or use a light you can point. The phone flashlight works well here, and in LoupeLens you can dim it so you are not shining a full-brightness beam into a sensitive ear.
- Lift the flap and look at the inside surface. Check for redness, scratches, scabs, and swelling. Run a finger along the edge of the flap for lumps.
- Look into the canal opening. Gently pull the ear up and slightly back to straighten the vertical canal. You will see only the outer part; that is expected. Note the color of the skin and any debris.
- Smell. This sounds odd but it is one of the most reliable early indicators. A healthy ear smells of almost nothing.
- Press gently at the base of the ear. A squelching sound suggests fluid inside. Wincing suggests pain.
- Compare the two ears. Problems are often on one side only, so the other ear is your reference.
- Take a photo. One per ear, in the same light each week. When you suspect something is changing, the photos settle the question.
Using magnification
Most of a check needs only your eyes and a light. Magnification helps in a few specific places. At 3x to 5x you can tell whether debris is smooth wax or crumbly, whether the skin has tiny bumps or is just red, and whether a speck at the edge of the flap is dirt, a scab, or a tick. Because LoupeLens captures a photo with one tap, you can take the image quickly while the dog is still and examine it afterward at leisure, which is kinder to the dog than a long inspection.
Do not try to see deep into the canal with any tool. You cannot safely look past the bend at home, and the attempt will only distress the dog.
What vets use to look inside a dog’s ear
A dog’s ear canal is L-shaped: it runs down (the vertical canal), then turns toward the head (the horizontal canal) before reaching the eardrum. At home you can only see the top of the vertical canal. Vets use an otoscope, a handheld light with a magnifying lens and a cone-shaped tip, to see around the bend and check the eardrum. They may also take a swab and look at it under a microscope to tell yeast, bacteria and mites apart.
That is why a home check is about spotting change, not diagnosing. Do not insert anything into the canal to see further. A phone light and magnifier at the opening, plus a photo for the vet, is the safe limit.
If your dog won’t let you check its ears
- Go in stages. Day one, touch the ear and give a treat. Day two, lift the flap. Build up to the full check over a week.
- Pick the right moment. After exercise, when the dog is tired and settled, not when it is excited.
- Get a second person to offer treats or a lick mat while you look.
- Keep it short. Thirty seconds and a reward beats a five-minute struggle.
- Take a photo instead of a long look. Lift the flap, tap to capture, release, then study the photo.
A dog that used to accept ear handling and now pulls away may be in pain. That change alone is worth mentioning to your vet.
Signs that mean a vet visit
| What you see or notice | What it may suggest |
|---|---|
| Dark, crumbly debris like coffee grounds | Ear mites, common in puppies and in dogs around cats |
| Yellow, brown, or greenish discharge with a foul smell | Bacterial infection |
| Brown waxy discharge with a sweet or musty smell | Yeast overgrowth |
| Red, swollen, thickened canal | Inflammation, often chronic or allergy related |
| Head tilt, loss of balance, circling | Possible middle or inner ear involvement; see a vet promptly |
| Soft, fluid-filled swelling of the flap | Aural hematoma, usually from violent head shaking |
| Sudden frantic scratching of one ear after a walk | Foreign body such as a grass seed |
Ear problems rarely resolve on their own, and an untreated infection can become chronic and much harder to manage. If in doubt, a vet can look down the canal with an otoscope and take a swab to see what is growing, which determines the right treatment.
Cleaning: what to do and what to avoid
Healthy ears with little debris do not need routine cleaning, and over-cleaning can irritate them. If your vet has recommended cleaning, or your dog is a swimmer who accumulates wax:
- Use a cleaner made for dogs' ears. Do not use alcohol, hydrogen peroxide, or human products unless a vet has told you to.
- Fill the canal with the cleaner, massage the base of the ear for a few seconds, then step back and let the dog shake. Wipe out what comes up with cotton balls or gauze.
- Clean only what you can see. Never push a cotton swab into the canal; it compacts debris against the bend and can damage the eardrum.
- Dry the ears after swimming or baths by wiping the flap and opening.
If the ear is painful, bleeding, or you suspect the eardrum is damaged, do not put anything in it. See a vet first.
Keeping a record
A weekly photo of each ear takes a minute and builds a record your vet will find genuinely useful. You can show when a change started and how quickly it progressed, and compare a treated ear with the photos from before treatment. Captures from LoupeLens go into their own album in Photos, so the dog's ear history stays in one place.

Frequently asked questions
What do healthy dog ears look like?
Healthy dog ears are pale pink inside (or the dog’s usual skin color), have little or no wax, smell of almost nothing, and show no swelling, scabs or discharge. The dog is relaxed when you touch them. Compare with the other ear and with photos from previous weeks.
What instrument do vets use to check a dog’s ears?
Vets use an otoscope, a handheld light with a magnifying lens and a cone-shaped tip that lets them see down the L-shaped canal to the eardrum. At home you can only see the canal opening, so use a light and a magnifier there and leave the deeper look to the vet.
How often should I check my dog's ears?
Once a week is a good routine for most dogs. Dogs with floppy ears, allergies, or a habit of swimming benefit from a quick look after each swim or bath as well. Checking regularly teaches you what normal looks like so changes stand out.
What do ear mites look like in a dog's ear?
The classic sign is dark brown or black crumbly debris resembling coffee grounds, often with intense itching and head shaking. The mites themselves are tiny white specks that are hard to see without magnification. A vet confirms the diagnosis with a swab and prescribes treatment.
Can I use cotton swabs to clean my dog's ears?
Not inside the canal. Swabs push debris down against the bend in the L-shaped canal and risk damaging the eardrum. Use them, or better a cotton pad, only on the inner surface of the flap and the parts of the opening you can see.
What does a dog ear infection smell like?
Yeast overgrowth typically smells sweet, musty, or like bread. Bacterial infections smell foul or rotten. A healthy ear has almost no smell, so any strong odor is a reason to look more closely and, if it persists, see a vet.
How do I check my dog’s ears if it won’t let me?
Build up slowly: touch the ear and reward, then lift the flap and reward, over several days. Check when the dog is tired after a walk, ask someone to hold treats, and take a quick photo instead of a long look. If a dog suddenly resists ear handling, it may be in pain and should see a vet.
