Dog Ear Cleaners (2026): How to Clean Ears, and When It's an Infection for the Vet

Most dogs need their ears cleaned only when you can see wax or smell something, and some never need it. When you do clean, use a gentle, sting-free cleaner such as Virbac Epi-Otic Advanced, fill the canal, massage, let the dog shake, and wipe with cotton or gauze. If the ear is red, swollen, smelly, painful or has discharge, that is not a cleaning job: it is a vet visit. This page follows the cleaning steps in VCA Animal Hospitals' ear cleaning guide and the ASPCA's, lists the warning signs, and compares four over-the-counter cleaners sold by Amazon.com.

How we chose: we did not test these cleaners; we read the makers' and Amazon listings, kept only cleaners sold by Amazon.com that were in stock on September 28, 2026, and left out anything sold as an infection treatment.

Four ear cleaners side by side

VCA's advice on choosing is short: "It is highly recommended to use a good-quality ear cleaner." It adds that cleaners with hydrogen peroxide or alcohol "can cause irritation in the ear canal, especially if the canal is inflamed or ulcerated," and that "your veterinarian can help you decide which ear-cleaning solution is best for your pet." None of the four picks lists alcohol. The ASPCA's dog grooming page is looser and names mineral oil and hydrogen peroxide as options alongside a formulated ear cleaner; if your dog's ears are at all irritated, VCA's caution is the one to follow.

Does your dog need its ears cleaned at all?

Often not. VCA answers the question directly: "No, not all dogs need their ears cleaned." It says over-cleaning "may cause irritation in the ear canal, which can lead to infection," and that some dogs with healthy, clean ears may never need cleaning. It recommends cleaning when you notice discharge or an odor.

The ASPCA wants ear checks to be part of a regular grooming routine, "especially important for dogs who produce excessive earwax or have a lot of inner-ear hair," and warns: "Don't clean your dog's ears so frequently or deeply as to cause irritation, and take care to never insert anything into your dog's ear canal."

Some dogs are more likely to have trouble. VCA's ear infection page says breeds "with large, floppy, or hairy ears are more prone to ear infections (e.g., cocker spaniels, miniature poodles, Old English sheepdogs), but they can occur in any breed." Virbac pitches Epi-Otic at allergic pets, frequent swimmers and floppy-eared breeds for the same reason: moisture and wax build up.

How to clean a dog's ears, step by step

VCA's method, condensed:

1. Get set up. You need the cleaner, cotton balls or gauze, and treats. VCA says you need no special equipment.
2. Fill the canal. Hold the ear flap up and squeeze in enough cleaner "to completely fill the ear canal." Do not put the tip of the bottle into the ear; if it touches the ear, VCA says to wipe the tip with alcohol before the next use.
3. Massage. Gently massage the base of the ear, below the opening, "for about 30 seconds." You should hear a squishing sound as the cleaner loosens debris.
4. Let the dog shake. Shaking moves the remaining cleaner and debris up to the opening. Stand back or hold a towel.
5. Wipe out what comes up. Use a cotton ball or gauze, and "only go into the ear canal as far as your finger will reach."
6. Repeat on the other ear, then reward your dog.

The ASPCA adds a detail for the ear flap: "Fold your pet's ear back gently and wipe away any debris or earwax that you can see on the underside," and "be sure to lift away the dirt and wax rather than rubbing it into the ear." It also suggests having your vet demonstrate the first time, because "inner-ear skin is delicate."

Key point: no cotton-tipped swabs, ever. VCA says Q-tips risk "puncturing the ear drum or causing trauma to the ear canal," and "can push debris further into the ear canal."

For bath time, the ASPCA suggests "placing a large cotton ball in each ear until the bath is over" and not spraying water directly into the ears. Our dog shampoo guide covers the rest of the bath, and our brush guide by coat type covers the long, hairy ears that trap wax.

When it's an infection, not dirt

The ASPCA lists the signs that mean "see your veterinarian as soon as possible":

• Ear scratching
• Brown, yellow or bloody discharge
• Odor in the ear
• Redness
• Swelling
• Crusted or scabby skin on the near ear flap

It also mentions hair loss around the ear, head shaking, loss of balance and hearing loss. VCA adds that infected ears are painful, that "many dogs will shake their heads and scratch their ears," and that a black or yellowish discharge is common.

And VCA's cleaning guide is clear about the order of events: "If your dog's ears are red, inflamed, or painful, consult with your veterinarian prior to cleaning."

Why over-the-counter drops can't replace the exam

VCA's ear infection page asks the question owners ask, "Can I just treat these symptoms with over-the-counter ear drops?", and answers "No." Its reasons:

• The cause varies. "There are several kinds of bacteria and at least one type of fungus that commonly cause ear infections," and ear mites cause similar signs. Sometimes the problem is "a foreign body, a polyp, or a tumor," which medicine alone will not fix.
• The eardrum matters. "Your dog must be examined to ensure the eardrum is intact. If the eardrum is ruptured, administration of certain medications can result in loss of hearing."
• There is often something underneath. VCA says allergies are involved in as many as 43% of ear infection cases, and that untreated infections can lead to painful swelling of the ear flap or a damaged eardrum.

Your vet looks with an otoscope and may check material from the ear under a microscope to choose the right medicine. If medicine is prescribed, VCA says to clean the ears first and then apply it.

About Zymox. Zymox, from Pet King Brands, is widely sold on Amazon, and its enzymatic ear solution is sold there "to Soothe Ear Infections," per the listing titles. Zymox makes versions with 0.5% or 1% hydrocortisone "for itch relief," a hydrocortisone-free version it says "can be used for a longer duration," and a separate enzymatic ear cleanser for waxy, dirty ears. Its FAQ says not to use other ear preparations before or during a course of its ear solution. We did not give it a card: the listings we found were sold by a third-party storefront, not Amazon.com or a store in the brand's name, and the ear solutions are sold for infection, which is a vet's diagnosis first. If your vet suggests it, ask which version.

This page is general information, not veterinary advice (more on that). Ask your vet before putting anything into an ear that is red, sore or smelly.

Cats, tea tree oil and a dog-only cleaner

Epi-Otic, Douxo SPA and the Veterinary Formula cleaner are all sold for dogs and cats. Vet's Best Ear Relief Wash is sold for dogs, and Vet's Best lists tea tree oil and clove oil among its ingredients. Pet Poison Helpline's essential oils and cats page names both among the oils "known to cause poisoning in cats," and says cats lack a liver enzyme needed to clear them. Vet's Best also says plainly that its ear products "do not contain any antimicrobial, antifungal, or antibacterial ingredients" and to see your veterinarian if you suspect an infection. Use it on a dog, store it away from cats, and pick one of the other three if you have both.

Ear care sits alongside nails and teeth in a grooming routine: our nail clipper and grinder guide and pet dental care guide cover the other two.

Frequently Asked Questions

How often should I clean my dog's ears?

Only as often as they need it. VCA says not all dogs need their ears cleaned, over-cleaning can cause irritation, and cleaning is recommended when you notice discharge or odor. Your vet can set a schedule for a dog prone to problems.

Can I use cotton swabs to clean my dog's ears?

No. VCA says cotton-tipped applicators risk puncturing the eardrum or damaging the canal, and push debris further in. Use cotton balls or gauze, only as far as your finger reaches.

Is hydrogen peroxide safe for cleaning dog ears?

The ASPCA lists it as an option, but VCA says cleaners with hydrogen peroxide or alcohol can irritate the ear canal, especially an inflamed one. A formulated, alcohol-free cleaner is the gentler choice.

Can an ear cleaner cure an ear infection?

No. VCA says your vet must diagnose the cause, since several bacteria, a fungus, mites or a foreign body can be responsible, and must check that the eardrum is intact before some medicines are used.
