How Summer Swimming Can Put Your Pet’s Ears at Risk

Is Your Dog’s Favorite Summer Activity Putting Their Ears at Risk?

Does your dog love diving into pools or paddling in lakes during summer? Or maybe your curious cat gets splashed during bath time or outdoor adventures? It’s all fun and games – until ear infections sneak in.

Most pet parents don’t realize that up to 20% of dogs suffer from ear infections, many triggered by trapped water after swimming or bathing. That fun summer splash could lead to weeks of discomfort, vet visits, and treatment.

So, before your pet takes its next dip, here’s what you need to know to protect its ears.

What Is Swimmer’s Ear in Pets?

Swimmer’s ear, or otitis externa, is an infection or inflammation of the outer ear canal. It’s especially common in dogs who swim or are bathed frequently. While cats are less likely to be affected, they’re not immune, especially if they have allergies or spend time in wet environments.

Why Water Causes Trouble

Dogs have long, narrow, L-shaped ear canals. This design helps protect the inner ear but also traps moisture easily. Add floppy ears or lots of ear hair, and you have a cozy, humid home for bacteria and yeast to grow.

Pool water, lakes, and even bathwater can be culprits. Chlorine strips natural defenses. Allergies make the skin more vulnerable. And just one swim can set off an infection, especially in sensitive pets.

Signs Your Pet Has an Ear Infection

Look out for these common symptoms:

• Head shaking or constant scratching
• Redness, swelling, or foul odor
• Dark discharge or waxy buildup
• Sensitivity or pain when touched
• Rubbing ears on furniture or carpet
• Balance issues (in severe cases)

Don’t wait – early treatment is key to stopping the infection before it worsens.

How to Prevent Swimmer’s Ear

You don’t have to skip the summer fun. Just follow these ear care habits:

After Every Swim or Bath:

• Let your pet shake it out, then gently towel-dry their ears.
• Use a vet-approved ear-drying solution for dogs prone to infections.

Keep Ears Clean:

• Ask your vet how often to clean your pet’s ears – it varies by breed and health.
• Avoid over-cleaning, which can cause irritation.

Avoid These Mistakes:

• Never insert Q-tips or probes deep into the ear canal.
• Don’t use homemade remedies unless directed by your vet.

Pro Tips:

• Trim inner ear hair if recommended by your groomer or vet.
• Avoid dirty ponds or murky water.
• Manage allergies and ear mites to lower infection risk.

What If an Infection Happens?

Your vet may:

• Examine the ear and do a swab test
• Prescribe antibiotic or antifungal ear drops
• Clean the ear professionally
• Address root causes like allergies or parasites

Avoid DIY treatments. Using the wrong product can make things worse or even damage the ear canal.

Chronic Infections? Here’s What That Could Mean

Recurring ear infections might signal deeper health concerns, like untreated allergies, hormonal issues, or structural ear problems. Don’t ignore them—get your vet’s guidance on long-term solutions.

Keep the Splash, Ditch the Itch

Summer should be full of fun, not vet visits. With some awareness and a few smart habits, you can protect your pet from painful ear infections and let them enjoy every swim, splash, and bath.

Stay prepared, stay informed, and keep those ears dry.

Frequently Asked Questions

Can dogs really get ear infections just from swimming once?

Yes, even a single swim can trap moisture in the ear canal, creating the perfect environment for bacteria or yeast to grow, especially in breeds prone to ear issues.

How do I safely dry my pet’s ears after swimming or bathing?

Let your pet shake off excess water, then gently pat the outer ear with a clean towel. For high-risk dogs, use a vet-recommended ear-drying solution—never insert anything deep into the ear.

Are cats at risk of swimmer’s ear, too?

While less common, cats can develop ear infections, especially if they have allergies, get bathed frequently, or have underlying health conditions.

What should I do if my pet shows signs of an ear infection?

Contact your veterinarian right away. Early treatment with medicated ear drops or cleansers can prevent the infection from worsening or spreading deeper.

How can I tell the difference between normal earwax and an infection?

Normal earwax is usually light-colored and odorless. Infections often cause dark, smelly discharge, redness, swelling, or sensitivity—paired with head shaking or scratching.
