Ears and eyes are where problems show up first and get worse fastest. An ear infection that's mildly itchy on Monday can be a painful, ruptured eardrum by the weekend. An eye that looks slightly cloudy can be glaucoma, which permanently damages vision in a day or two. The good news: a two-minute weekly check catches almost all of it early.
A quick note: This is general education, not a diagnosis. Eye problems in particular move fast — when in doubt, call your vet the same day rather than waiting to see if it clears up.
The two-minute weekly check
Once a week, in good light, with your dog relaxed:
1. Lift each ear flap. Look at the visible part of the canal, then smell it.
2. Look at each eye straight on. Compare left to right — symmetry is what you're checking.
3. Run a thumb gently around each eye and the base of each ear. You're feeling for heat, swelling, or a flinch.
Do it after a walk or during a cuddle and your dog will barely notice. What you're learning is your dog's normal, so the day something changes, you spot it immediately.
What healthy looks like
| What to check | Healthy | Concerning |
|---|---|---|
| Ear skin | Pale pink, smooth | Red, swollen, thickened, scabby |
| Ear smell | Almost none | Yeasty, sweet, or foul |
| Ear discharge | None to a trace of light wax | Brown, black, yellow, or coffee-ground-like |
| Eye surface | Clear and glossy | Cloudy, blue-grey haze, dull |
| Eye whites | White, with fine visible vessels | Bloodshot, bright red |
| Eye discharge | A little clear or grey "sleep" in the corner | Green, yellow, thick, or a sudden increase |
| Pupils | Equal size, both responsive | Unequal, or one not reacting to light |
How to clean your dog's ears
Only clean when there's a reason to — visible wax, after swimming, or as your vet directed. Over-cleaning strips the natural protective barrier and can cause the very irritation you're trying to prevent.
What you need: a vet-approved ear cleaner, cotton balls or gauze, a towel, treats.
1. Fill the ear canal with the cleaner until it pools at the opening. Don't touch the nozzle to the ear.
2. Massage the base of the ear — the firm part below the flap — for 20–30 seconds. You should hear a squelching sound. This is the step that actually does the work.
3. Let your dog shake their head. Stand back; this is why you have the towel.
4. Wipe the visible part of the canal and the inside of the flap with a cotton ball. Stop where your finger stops.
5. Treat, praise, repeat on the other side.
How often: most dogs, once a month or less. Floppy-eared breeds, dogs who swim, and dogs with allergies may need weekly — your vet will tell you.
Never: push a cotton swab down the canal (it packs debris against the eardrum), use hydrogen peroxide, vinegar, or rubbing alcohol, or clean an ear that's already red and painful without a vet checking it first — if the eardrum is ruptured, some cleaners cause real damage.
How to clean your dog's eyes
Far simpler, and mostly about hygiene around the eye rather than in it.
- •Dampen a soft cloth or cotton pad with warm water or a sterile saline eye wash.
- •Wipe from the inner corner outward, using a fresh pad for each eye so you don't move an infection across.
- •Keep the hair around the eyes trimmed — long facial hair scratches the cornea and wicks tears onto the face.
- •For tear stains, wipe daily and keep the fur dry. The stain is a yeast that grows in constantly damp fur; drying is the whole treatment.
Never use human eye drops, redness-relief products, or contact-lens solution on your dog. Some contain ingredients that are actively harmful to a dog's eye, and "redness" is a symptom you want the vet to see, not mask.
Breeds that need extra attention
| Risk | Breeds | Why |
|---|---|---|
| Ear infections | Cocker Spaniel, Basset Hound, Labrador, Poodle, Shar-Pei | Heavy flaps and narrow or hairy canals trap moisture |
| Swimmer's ear | Any water-loving dog — Labs, Goldens, Spaniels | Water in the canal after every swim |
| Corneal ulcers & eye trauma | Pug, French Bulldog, Shih Tzu, Boston Terrier, Pekingese | Shallow sockets, prominent eyes, incomplete blinking |
| Dry eye (KCS) | Bulldog, Cocker Spaniel, West Highland White, Lhasa Apso | Reduced tear production |
| Glaucoma | Cocker Spaniel, Basset Hound, Chow Chow, Shar-Pei, Beagle | Inherited drainage-angle defects |
| Allergy-driven ear disease | Retrievers, terriers, French Bulldogs | Ears are often the first place a food or environmental allergy shows |
Red flags: call the vet
Ears — book an appointment
- •Persistent head shaking or scratching at one ear
- •Brown, yellow, or bloody discharge; a strong yeasty smell
- •Redness, swelling, heat, or pain when touched
- •A swollen, spongy ear flap (an aural hematoma, from shaking)
Ears — same day
- •Head tilt, circling, loss of balance, or flickering eyes — this suggests the middle or inner ear is involved
- •Sudden apparent deafness
Eyes — same day, treat as urgent
- •Squinting, holding an eye shut, or pawing at the face
- •Cloudiness, a blue-grey haze, or a visibly bulging eye
- •Green or yellow discharge
- •A very red eye, especially with an enlarged pupil — possible glaucoma, which can destroy vision within 24–48 hours
- •Any visible injury, or bumping into furniture
A dog holding one eye closed is in pain and has an eye problem until proven otherwise. That one is worth an emergency call.
Why the same ear infection keeps coming back
Recurring ear infections are usually not an ear problem. In most repeat cases the underlying driver is allergy — food or environmental — and the ear is simply where it surfaces. Treating each flare-up with drops while ignoring the cause guarantees the next flare-up.
The other half of the problem is adherence. Ear medication is typically prescribed twice a day for 7–14 days, and the itch stops around day four. Owners stop there, the surviving organisms rebound, and the next round needs a stronger drug.
That's a scheduling problem more than a medical one. In PetLover you can set a medication two to four times a day and get a reminder for each dose until the course is finished, not just the first one. Snap a photo of the ear on day one and day five and you have a real before-and-after to show the vet instead of describing it from memory — and every treatment lands on the same health timeline, so at the next visit you can show that this is the third infection this year, which is the fact that gets the underlying allergy investigated.
A note on cats
Most of this transfers, with two differences: cats need ear cleaning far less often, and dark, crumbly, coffee-ground debris in a cat's ears usually means ear mites — highly contagious to other pets in the house, and needing treatment for all of them, not just the itchy one.
Frequently asked questions
How often should I clean my dog's ears?
Only as needed. For most dogs that's monthly or less; for floppy-eared breeds, swimmers, and allergy dogs it may be weekly. Cleaning healthy ears too often causes irritation.
Can I use human eye drops on my dog?
No. Redness-relief drops and many human formulations can harm a dog's eye. Plain sterile saline eye wash is safe for rinsing; anything medicated should come from your vet.
What does a dog ear infection smell like?
Most commonly a sweet, yeasty smell. A foul or rotten smell suggests a bacterial infection and needs attention quickly.
Are tear stains harmful?
The stain itself is cosmetic. But a sudden increase in tearing isn't — it can signal a blocked tear duct, an ingrown lash, allergies, or a corneal problem. Worth a check.
Should I pluck the hair from my dog's ears?
Only if your vet or groomer specifically recommends it for your dog. Routine plucking creates micro-tears that can invite infection; for some breeds with dense canal hair it genuinely helps. Ask first.
The bottom line
Learn what your dog's normal ears and eyes look and smell like, check weekly, clean only when there's a reason, and never improvise with human products. Then treat any eye change as urgent and any third ear infection in a year as a sign to look for the cause, not just the cure.
