Dog Ear Infections After Swimming in Florida: Signs, Prevention, and When to Call the Vet

In St. Petersburg, a “normal” week can include a backyard pool, a quick beach trip, and a surprise afternoon storm. If your dog loves water, you’re not alone. The not-so-fun part: all that moisture can lead to ear irritation and ear infections.

If you’ve noticed head shaking after swimming, a funky smell from the ears, or your dog suddenly acting sensitive when you touch their head, it’s worth paying attention. Ear infections are uncomfortable, and they can get worse fast in warm, humid Florida weather.

Why swimming can cause ear problems in Florida

Most swimmer-related ear infections in dogs happen in the outer ear canal. Water gets trapped, the ear stays damp, and yeast or bacteria can overgrow.

Some dogs are more likely to have trouble, especially if they have:

• Floppy ears (less airflow)
• Narrow ear canals
• Lots of ear hair
• Allergies (itchy, inflamed skin makes infection more likely)

Common signs of an ear infection

Watch for these signs after swimming, baths, or rainy days:

• Head shaking or ear flapping
• Scratching at one or both ears
• Redness inside the ear flap
• Bad smell (yeasty or sour)
• Discharge (brown, yellow, or black debris)
• Pain or pulling away when you touch the ear

Call the vet ASAP if you see:

• Severe pain or swelling
• Head tilt, loss of balance, or stumbling
• Bleeding from the ear

What you can do at home (safe steps)

If your dog just swam and the ears look normal, prevention is mostly about keeping things dry.

After-swim basics

• Towel-dry the outer ear flap after swimming or baths.
• Limit repeat swims back-to-back if your dog tends to flare up (ears stay wet longer than you think).
• Ask us about a vet-recommended ear rinse if your dog swims often. Using the wrong product can irritate the ear canal.

What NOT to do

• No Q-tips in the ear canal.
• Don’t use home remedies like vinegar, peroxide, or oils.
• Don’t use leftover ear meds from an old infection.
• If the ear is painful, stop cleaning and schedule an exam.

Why some dogs keep getting ear infections

If your dog gets ear infections over and over, there’s usually an underlying cause. Swimming may be the trigger, but it’s often not the whole story.

Common root causes we see in the Tampa Bay area include:

• Environmental allergies (very common here)
• Skin conditions that affect the ear canal
• Ear anatomy that traps moisture and reduces airflow

The good news: once we identify the “why,” we can build a plan to reduce flare-ups and keep your dog comfortable.

What a vet visit for ear trouble usually includes

Many ear infections look similar at home, but they don’t always need the same treatment. At Community Animal Hospitals, an ear visit may include:

• Ear exam with an otoscope
• Ear cytology (checking a sample under the microscope to see yeast/bacteria)
• Cleaning when it’s safe and helpful
• A treatment plan based on what’s actually going on in your dog’s ear

How to reduce ear infections long-term

If your dog is a frequent swimmer (or just lives for the hose), we can help you set up a practical routine. Depending on your dog, that might include:

• A consistent after-swim ear drying plan
• Periodic maintenance ear cleaning with a vet-approved product
• Managing allergies so the ear canal skin stays healthier
• Scheduling earlier rechecks if your dog tends to relapse

One quick reminder: if an ear infection is brewing, swimming can keep it going. It’s usually best to avoid water activities until the ear is healed.

When to call Community Animal Hospitals

If you’re seeing odor, discharge, swelling, or repeated head shaking—especially after swimming—don’t wait it out. Ear infections are painful, and early treatment is usually simpler.
