How to Check Your Dog's Ears [What Healthy Ears Look Like]
A healthy dog ear is pale pink inside (or the dog's usual skin pigment), smells of almost nothing, and has no wax or only a little pale yellow to light brown wax. To check, 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.
A look inside your dog's ears once a week takes about two minutes and catches most problems while they are still minor. Below: what a normal ear looks like, what different wax colors can mean, how to do the check, and when to see a vet.
What healthy dog ears look like
The skin on the inside of the flap and around the canal opening is pale pink and smooth. Dogs with dark skin can have grey, brown or black patches of pigment there; that is normal if it has always been there and the skin is not raised or sore.
- Color: pale pink, or the dog's usual pigment. Not red, dark pink, or hot to the touch.
- Wax: none, or a small amount of pale yellow to light brown wax. A thin film near the opening is normal for many dogs.
- Smell: almost none. A faint waxy scent is fine; a sweet, yeasty, sour or rotten smell is not.
- Skin: smooth, with no swelling, scabs, crusts, bumps or thickened areas.
- Behavior: the dog stays relaxed when you handle the ear and does not shake its head or scratch at it often.
Normal varies between dogs. Some breeds make more wax or have hair growing in the canal, so what matters is your own dog's baseline and any change from it.
Inside a dog's ear: what you can see at home
A dog's ear canal is shaped like an L. It drops down from the opening (the vertical canal), then turns toward the head (the horizontal canal) before it reaches the eardrum. At home you can see only the top of the vertical part. The bend protects the eardrum but also traps warmth and moisture, which yeast and bacteria like, so an infection can build for a while before the dog is obviously uncomfortable.
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 little pale yellow to light brown wax | Dark brown or black 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 |
Dog ear wax colors at a glance
| What you see | What it can mean |
|---|---|
| Pale yellow to light brown, small amount, little smell | Normal |
| Dark brown and waxy, more than usual | Often yeast or allergy-related inflammation, especially with itching or smell |
| Black or very dark, dry and crumbly like coffee grounds | Often ear mites, especially in puppies and dogs that live with cats |
| Brown with a sweet, musty or bread-like smell | Often yeast overgrowth |
| Yellow or green, wet or pus-like, bad smell | Often a bacterial infection |
| Red or bloody | A wound, damage from scratching, or a deeper problem |
Color is a clue, not a diagnosis. A vet tells yeast, bacteria and mites apart by looking down the canal with an otoscope and checking a swab under a microscope. For more colors, textures and what to do about each, see the dog ear wax color chart.
Why weekly checks are worth it
Dogs with floppy ears, hairy ear canals, allergies or a habit of swimming get ear problems more often and gain the most from a routine. Any dog can still pick up an infection, a grass seed or mites. Checking every week also teaches you what your dog's ears normally look and smell like, so a change is easy to spot.
Step-by-step check
- Pick a calm moment. After a walk works well, when the dog is relaxed. Have a treat ready, and keep the first few checks short and pleasant.
- Get good light. Sit near a window or use a light you can point. A phone flashlight works; 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 lift the ear up and slightly back to straighten the vertical canal. You will see only the outer part, which is expected. Note the skin color and any wax or debris.
- Smell. A change in smell often shows up before you see much else. A healthy ear smells of almost nothing.
- Press gently at the base of the ear. A squelching sound suggests fluid in the canal. 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 think something is changing, the photos show whether it is.
Using magnification
Most of a check needs only your eyes and a light. Magnification helps in a few places. At 3x to 5x you can tell whether debris is smooth wax or dry and 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. A quick photo while the dog is still lets you study the detail afterward, which is easier on 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 trying will only upset the dog.
What vets use to look inside a dog's ear
Vets use an otoscope, a handheld light with a magnifying lens and a cone-shaped tip, to see around the bend of the canal and check the eardrum. They often take a swab and look at it under a microscope (ear cytology) to tell yeast, bacteria and mites apart, because the right treatment depends on which it is.
A home check is for spotting change, not for diagnosing. Do not insert anything into the canal to see further. A 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
- Build up in stages. On day one, touch the ear and give a treat. On day two, lift the flap. Work up to the full check over a week.
- Check after exercise, when the dog is tired and settled, not when it is excited.
- Ask a second person to offer treats or a lick mat while you look.
- Keep it short. Thirty seconds and a reward works better than a five-minute struggle.
- Take a photo instead of a long look: lift the flap, 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 |
|---|---|
| Discharge, a strong smell, or wax that looks different from usual | Infection, yeast or mites (see the wax color table above) |
| 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 the same day |
| Soft, fluid-filled swelling of the flap | Aural hematoma, usually from hard head shaking |
| Sudden frantic scratching or head shaking after a walk | Foreign body such as a grass seed |
| Pain when you touch the ear, or bleeding | Infection, injury or a problem deeper in the canal |
Ear infections usually need treatment, and one left alone can become chronic and harder to manage. If you are unsure, book a vet visit; a swab tells the vet what is growing and which treatment fits.
Cleaning: what to do and what to avoid
Healthy ears with little wax do not need routine cleaning, and over-cleaning can irritate them. If your vet has recommended cleaning, or your dog swims and builds up wax:
- Use an ear cleaner made for dogs. 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 away what comes up with cotton balls or gauze.
- Clean only what you can see. Never push a cotton swab into the canal; it packs debris against the bend and can damage the eardrum.
- Dry the ears after swimming or baths by wiping the flap and the opening.
If the ear is painful or bleeding, or you think the eardrum may be damaged, do not put anything in it. See a vet first.
Keeping a record
A weekly photo of each ear takes a minute and gives your vet something concrete: when a change started, how fast it progressed, and how a treated ear compares with before. LoupeLens saves its captures to their own album in Photos, so the ear photos stay 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 pigment), have no wax or only a little pale yellow to light brown 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 color should dog ear wax be?
Normal dog ear wax is pale yellow to light brown, sparse, and has little smell. Dark brown, black and crumbly, yellow or green, or bloody discharge can point to yeast, mites, infection or injury, and is a reason to have a vet look.
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. They often also check a swab under a microscope. 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 that looks like coffee grounds, often with strong itching and head shaking. The mites themselves are tiny pale specks that are hard to see without magnification. A vet confirms them 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 can damage the eardrum. Use a cotton pad or gauze only on the inside of the flap and the parts of the opening you can see.
What does a dog ear infection smell like?
Yeast overgrowth often smells sweet, musty or like bread. Bacterial infections tend to smell foul or rotten. A healthy ear has almost no smell, so a strong odor is a reason to look closely and, if it persists, to 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.
