How to Clean a Dog's Ears: When and How to Do It Safely

When to clean — and when not to
Routine cleaning is not necessary for every dog. Breeds with heavy, floppy ears, dogs that swim often, or those with a history of infections may benefit from periodic cleaning as advised by your vet. If the ears smell yeasty, look red, or your dog shakes their head or scratches constantly, that is likely infection or mites — cleaning alone will not fix it and may worsen irritation.
What you’ll need
- Dog ear cleaner (liquid formulated for canine pH)
- Cotton wool balls or gauze squares
- Towel (your dog will shake)
- Treats
Avoid homemade mixes unless your vet specifically recommends them.
The cleaning process
Rest your dog in a comfortable position. Lift the ear flap and squeeze cleaner into the canal until it is full — this feels odd to owners but is correct technique. Massage the base of the ear where it meets the head; you should hear a squelching sound. Step back and let your dog shake vigorously. Wipe the inner flap and the opening of the canal with damp cotton wool. Repeat on the other ear with fresh cotton.
Preventing ear problems
Dry ears thoroughly after swimming or bathing. Keep hair around the ear opening trimmed if your groomer or vet advises it. Treat allergies and skin conditions promptly — they often drive recurring ear infections. Regular check-ups catch problems before they become chronic.
Red flags — see your vet
- Dark brown or black crumbly discharge (possible mites)
- Strong odour or thick yellow/green pus
- Pain when touched, yelping, or aggression during handling
- Loss of balance or head tilt
- Swelling or the ear feeling hot

Frequently asked questions
How often should I clean my dog's ears?
Healthy ears often need no routine cleaning — only clean when there is visible wax buildup or your vet recommends it for your breed.
Can I use cotton buds in my dog's ears?
Never insert cotton buds into the ear canal — they push debris deeper and can damage the eardrum.
What does a healthy dog ear look like?
Pale pink, clean-smelling, with minimal wax. Redness, swelling, or a yeasty odour suggests infection.
Are floppy-eared dogs more prone to ear problems?
Yes — reduced airflow in breeds like Cocker Spaniels and Basset Hounds increases moisture and infection risk.
