Senior dogs — especially those with floppy ears — are prone to ear infections. Wax buildup, moisture trapped after baths, and reduced immune function combine to create a breeding ground for bacteria and yeast. Regular ear cleaning prevents infections before they start. Here are 4 veterinary-recommended products.

1. Best Overall: Virbac Epi-Otic Advanced Ear Cleanser
Virbac Epi-Otic is the #1 ear cleanser used in veterinary clinics. The formula uses salicylic acid (exfoliates dead skin cells inside the ear canal), lactic acid (creates an acidic environment where bacteria and yeast cannot grow), and PCMX (a gentle antimicrobial). It also contains a drying agent — critical because moisture trapped in the ear canal is the #1 cause of infections. The citrus scent is pleasant and does not linger. Use once weekly for maintenance; twice weekly during allergy season or after baths/swimming. The nozzle tip is designed to be gentle if your dog startles and bumps it against their ear. The 8oz bottle lasts 4-6 months with weekly use. Follow the standard ear cleaning technique: fill the ear canal, massage the base of the ear for 30 seconds (you will hear a squelching sound — that is the solution breaking up wax), then let your dog shake their head. Wipe the visible gunk from the outer ear with a cotton ball — never use Q-tips inside the ear canal. Reward with a treat afterward so your dog associates ear cleaning with something positive.
2. Best for Mild Infections: Zymox Otic Enzymatic Solution
Zymox uses a three-enzyme system (lactoperoxidase, lactoferrin, lysozyme) — the same enzymes found in tears and saliva that naturally kill bacteria. It is antibiotic-free, steroid-free, and safe for long-term use. If your dog’s ears are red, smelly, or have dark discharge (signs of a mild yeast or bacterial overgrowth), Zymox can resolve it without a vet visit — if caught early. Fill the ear canal, massage for 30 seconds, and DO NOT wipe afterward (the enzymes need to sit in the ear for 12-24 hours to work). Use once daily for 7 days for active issues; once weekly for maintenance. The 4oz bottle treats one ear infection and provides months of maintenance. The main limitation: Zymox will not penetrate heavy wax buildup — use Epi-Otic first to clean out wax, then Zymox to treat the underlying infection. If the ear is painful, swollen, or has pus rather than discharge, skip OTC treatment and see a vet — those are signs of a serious infection that needs prescription medication. Zymox is also available in a hydrocortisone version (1% hydrocortisone) for itchy ears — use the regular version for infections, the hydrocortisone version for allergies.
3. Best Value Kit: Vet’s Best Ear Cleaning Kit
Vet’s Best kit includes a 4oz liquid cleanser and 60 pre-moistened wipes — the wipes are for quick cleanings between full wash sessions. The cleanser uses witch hazel (natural astringent — dries the ear), chamomile (soothes irritation), and aloe vera (moisturizes without leaving residue). The formula is plant-based and alcohol-free (alcohol stings and dries too aggressively). The wipes are textured on one side (for gently scrubbing the outer ear folds) and smooth on the other (for wiping away debris). Use the wipes every 2-3 days and the liquid cleanser weekly. The kit lasts about 2 months for a medium-sized dog. The main limitation: the cleanser is less strong than the Virbac Epi-Otic for breaking down heavy wax. It is better for maintenance than treating existing buildup. Best for: a dog with generally clean ears who needs a routine maintenance kit, or a dog who fights the liquid bottle but tolerates wipes. Made in the USA with domestic and imported ingredients.
4. Easiest to Use: Pet MD Ear Wipes (120-Count)
For dogs who panic at the sight of a bottle, ear wipes are the solution. Pet MD wipes are pre-moistened with a gentle cleanser containing aloe vera, eucalyptus oil (natural antiseptic), and salicylic acid (mild exfoliant). They are textured for effective cleaning while being soft enough not to abrade sensitive ear skin. The round pad design fits over your finger — wrap it around your index finger and gently wipe the visible outer ear and the folds. Never push the wipe into the ear canal (you can pack wax deeper). The 120-count tub lasts 3-4 months with 2-3x weekly use. These do not replace a liquid ear wash for deep cleaning, but they are far better than doing nothing — and for a dog who fights the bottle, they are a compromise that actually gets done. Best for: maintenance between deep cleanings, or for dogs with mild wax buildup who do not need the full liquid treatment. Also excellent for cleaning wrinkles on flat-faced breeds (Pugs, Bulldogs) after walks. Alcohol-free, fragrance-free.
When to See the Vet (not the pet store)
- Foul, yeasty smell — indicates a yeast infection that OTC products may not resolve
- Head tilting, balance loss, or circling — the infection has reached the inner ear. Needs prescription antibiotics
- Pain when touching the ear — your dog yelps or pulls away. The ear needs a vet’s examination, not OTC treatment
- Blood or pus — possible ruptured eardrum or severe infection. Do not put anything in the ear; see a vet immediately
- Dark, coffee-ground-like debris — often ear mites (less common in senior dogs but possible). Needs prescription treatment
