Dog Ear Care After Swimming: A Simple Drying & Cleaning Routine

If your dog comes out of the pool, lake, beach, or backyard splash session with wet ears, the best default is simple: dry the visible ear gently, check for anything unusual, and do not turn every swim into an aggressive deep-cleaning session.

Moisture can contribute to ear problems in some dogs, especially dogs that swim often or have ears that stay damp. But ear infections are not caused by water alone. Allergies, ear anatomy, skin disease, debris, parasites, and other underlying factors can also matter. That is why a good post-swim routine focuses on drying and observation first, then uses cleaning products only when they are appropriate for the individual dog.

This guide is educational and is not a diagnosis or treatment plan. If an ear is painful, inflamed, producing discharge, smelling unusual, or repeatedly causing problems, contact your veterinarian rather than trying to solve it with increasingly intensive home cleaning.

After swimming, dry first

Once your dog is safely out of the water, let them shake naturally. Then use a clean, soft towel or cotton pad to dry the ear flap and the parts of the ear opening you can see and reach without pushing anything into the canal.

A practical post-swim sequence is:

1. Look at both ears. Check for new redness, swelling, debris, discharge, or obvious irritation.
2. Dry the external ear. Blot the ear flap and visible opening instead of rubbing aggressively.
3. Keep objects out of the canal. Do not insert cotton swabs or other narrow tools into the ear canal.
4. Notice your dog’s behavior. Repeated head shaking, scratching, rubbing the head, or pulling away from touch can be useful warning signs.
5. Clean only when it makes sense. If your veterinarian has recommended a post-swim cleaner or maintenance routine, follow those instructions. If the ear is healthy and clean, more cleaning is not automatically better.

Cornell’s canine health guidance notes that dogs with healthy ears generally need routine cleaning when dirt or debris is present, while over-cleaning itself can irritate the ears. Cornell also recommends routine cleaning when ears become wet after swimming or bathing, but the product and frequency should still fit the individual dog.

Why wet ears can become a problem

The external ear canal is lined with skin. When that environment stays chronically moist, the skin barrier can become less effective and conditions can become more favorable for opportunistic bacteria or yeast. Merck Veterinary Manual therefore recommends keeping ear canals dry and well ventilated, particularly for dogs with recurrent otitis externa.

That does not mean every wet ear will become infected. Think of moisture as one possible contributing factor rather than a complete explanation.

Some dogs may be more prone to recurring problems because of:

• ear shape or reduced ventilation;
• frequent swimming or bathing;
• allergies or other skin disease;
• excessive wax or debris;
• a history of recurrent ear inflammation or infection;
• other conditions your veterinarian identifies during an exam.

This distinction matters because repeatedly treating the moisture while missing an underlying allergy or chronic skin issue can lead to the same problem returning. AAHA guidance on allergic skin disease emphasizes ear evaluation as part of the workup when otitis is present.

If swimming is part of your dog’s routine, pair ear care with a broader water-safety plan that also covers supervision, safe entry and exit, drinking water, rinsing, heat, and local water conditions.

Cleaning is not the same thing as drying

Drying the visible ear after swimming is a low-complexity routine. Flushing the ear canal with a cleaning solution is a different step and should be done with an appropriate product and technique.

For dogs that truly need cleaning, Cornell describes a veterinarian-approved approach that generally involves placing the recommended solution in the canal, massaging the base of the ear, allowing the dog to shake, and then wiping loosened material from the accessible portion of the ear with cotton pads or balls. Your veterinarian can demonstrate the technique for your dog.

Avoid treating ear cleaning as a contest to remove every trace of wax. A small amount of normal wax is not the same thing as infection, and excessive cleaning can irritate healthy tissue.

Skip the improvised chemistry

Do not assume that a household liquid is safe because it seems like it would “dry” or disinfect an ear. Cornell specifically advises avoiding ear-cleaning solutions containing alcohol or hydrogen peroxide in general home use because they can irritate the ear.

Likewise, avoid homemade vinegar, essential-oil, or antiseptic mixtures unless your veterinarian has specifically recommended a formulation for your dog. The condition of the ear canal and eardrum matters when choosing what can safely go into the ear.

What you should not put deep in the ear canal

Cotton swabs are a familiar bathroom tool, but they are a poor choice for cleaning deep inside a dog’s ear. Cornell and Merck both caution against them because they can push debris farther into the canal.

The safer boundary for routine home care is the part you can comfortably see and reach without forcing an object down the canal. If material seems lodged deeper, or the dog is too uncomfortable to let you examine the ear, that is a reason for a veterinary assessment rather than more forceful cleaning.

The same logic applies to ear hair. Merck notes that removing hair can sometimes improve ventilation when excessive hair is contributing to a problem, but routine plucking is not automatically beneficial and can provoke inflammation. Ask your veterinarian or experienced groomer how to handle your dog’s specific coat and ear anatomy.

Know the signs that drying is no longer enough

A normal ear should not require you to fight your dog to touch it. Contact your veterinarian when you notice signs such as:

• redness or visible inflammation;
• persistent scratching or rubbing at one or both ears;
• repeated head shaking;
• unusual odor;
• increased wax or discharge;
• pain or sensitivity when the ear is touched;
• swelling around the ear;
• a recurring pattern after swimming, bathing, or allergy flare-ups.

These signs are not specific enough to tell you at home whether the problem is yeast, bacteria, allergy-related inflammation, parasites, a foreign body, or something else. A veterinarian may examine the canal with an otoscope and may use ear cytology to identify what is happening before choosing treatment.

If your dog suddenly develops severe pain, marked swelling, loss of balance, unusual eye movements, a head tilt, or other concerning neurologic signs, seek veterinary care promptly. Do not keep adding cleaners or medications while waiting to see whether the ear improves.

Frequent swimmers may need an individualized maintenance plan

A dog that swims once on vacation and a retriever that enters water several times each week do not necessarily need the same routine.

Merck notes that veterinarian-recommended drying or astringent products may be useful for some frequent swimmers. The key phrase is veterinarian-recommended. Products differ in their ingredients and intended uses, and a product that is reasonable for maintenance in a healthy ear may be inappropriate when the ear is inflamed or the eardrum’s condition is unknown.

For a frequent swimmer, ask your veterinary team:

• whether the ears need a cleanser after every swim or only when dirty;
• whether a drying product is appropriate;
• how often to use it;
• what early changes should trigger an exam;
• whether recurrent ear trouble could be related to allergies or another underlying condition.

That conversation can turn ear care from repeated guesswork into a simple maintenance plan.

Make ear checks part of grooming, not an emergency-only task

Ear care works better when your dog already knows that calm ear handling is part of normal life. During routine grooming and care, briefly lift each ear flap, look at the visible skin, and reward calm cooperation. That makes it easier to notice a change before the ear becomes painful enough that handling is difficult.

For dogs that dislike ear handling, build tolerance gradually. Touch near the ear, reward, and stop before the interaction becomes a struggle. Forcing a painful or frightened dog through a cleaning can make future care harder and may worsen irritation.

Keep towels, cotton pads, and any veterinarian-approved ear product together with your swim or grooming supplies. Check expiration dates and closures, and store liquids where pets and children cannot access them. When choosing any pet-care item, use the same purpose-and-fit mindset described in our guide to choosing the right dog product and our Product Safety principles.

A South Florida note without turning this into a local-only rule

Maxi Pawz is a Miami pet brand with nationwide availability, and ear anatomy does not change at the county line. This guide is intentionally nationwide rather than a Miami-specific SEO page.

Still, South Florida’s long warm season can make pools, beaches, lakes, and water play a regular part of a dog’s routine. If your dog swims frequently here—or anywhere else—make the post-swim ear check as automatic as offering fresh water and drying the coat. The useful habit is consistent observation, not a location-specific cleaning formula.

The simplest routine is usually the easiest to keep

After a swim, you do not need a complicated cabinet of products. Start with a towel, a quick look at the ears, and a clear sense of what is normal for your dog.

Dry the visible ear. Do not probe the canal. Do not over-clean. Use only an appropriate cleaner when it is actually needed. And treat pain, odor, discharge, persistent head shaking, or recurring trouble as reasons to involve your veterinarian.

That small routine connects swimming safety with everyday grooming—and helps you notice when a wet ear is just wet versus when your dog needs more help.
