Some dogs go years without needing an ear cleaning. Others develop recurring irritation after swimming or because of skin allergies. Prevention is not about cleaning every ear on a schedule: it is about spotting changes early and addressing the reason the ear keeps becoming inflamed.
Check your dog’s ears without overhandling them
Get to know what your dog’s healthy ears look and smell like. During routine grooming, lift the ear flap gently and check for redness, unexpected discharge, persistent odor, swelling, or sensitivity. Healthy ear canals should not require frequent probing or scrubbing.
Repeated head shaking, scratching, holding the head tilted, or pulling away when the ear is touched can indicate discomfort. Make an appointment if you notice these changes. A veterinarian can examine the canal and eardrum and may test a sample of debris to look for yeast, bacteria, or parasites.
Clean only when it is appropriate
Not all dogs benefit from regular cleaning. Cleaning a healthy ear too often can irritate the delicate lining. Ask your veterinarian whether your dog needs cleaning, which product to use, and how frequently. This is especially important for dogs with previous ear infections or ear surgery.
If your veterinarian has advised cleaning, use the recommended ear-cleaning solution and gauze or cotton to wipe the visible outer area. Avoid cotton-tipped swabs inside the canal, which can push material inward or cause injury. Do not pour household vinegar, peroxide, alcohol, or essential oils into the ears.
If an ear is red, swollen, unusually painful, or draining fluid, do not attempt deep cleaning first. It may be unsafe to place products in an ear when the eardrum’s condition is unknown.
Manage the factors that make infections recur
Water left in the ear and underlying allergies may contribute to irritation for some dogs. If your dog swims frequently, ask whether a veterinarian-recommended drying routine is appropriate. Do not assume floppy ears alone explain repeated infections: allergy, ear-canal changes, foreign material, and other causes may also be involved.
Dogs with recurring infections need a plan aimed at the underlying problem, not repeated courses of leftover drops. Follow-up checks matter because the ear may look improved before inflammation or infection has fully cleared.
When to seek veterinary care
Arrange a visit for odor, discharge, scratching, head shaking, or a painful ear. Seek urgent care for severe pain, a pronounced head tilt, loss of balance, sudden hearing changes, or swelling alongside other illness. These signs may indicate deeper involvement and should not be treated at home.

Common questions
Should I clean my dog’s ears every week?
Not automatically. Some healthy dogs do not need routine cleaning; your veterinarian can set a schedule for dogs with a documented reason.
Can I use a human ear drop?
No, unless your veterinarian specifically prescribes it. Different problems need different medications, and some products may be unsafe if the eardrum is damaged.
