How to Prevent Ear Infections in Dogs That Love to Swim

Dry your dog’s ears within 15 minutes after swimming, especially if they’ve got floppy ears like Labradors or Cocker Spaniels-those L-shaped canals trap moisture and breed bacteria. Use a soft towel, then a cool hairdryer 12 inches away, or a vet-approved drying solution. Try a mix of equal parts white vinegar and water to help evaporate residue, but skip it if you spot redness or pain. Regular checks and proper drying stop infections before they start-there’s more to keeping ears healthy than just water removal.

Stop Ear Infections: Dry Your Dog’s Ears After Swimming

While water may roll off your dog’s coat, it can easily get trapped in the L-shaped ear canals, especially after a long swim, so make drying a priority every time your pup leaves the water. That moisture trapped in the ear creates a warm, dark environment where bacteria and yeast thrive, increasing the risk of painful ear infections. Dogs with floppy ears-like Labradors, Goldens, or Cocker Spaniels-are especially prone due to poor air circulation. To prevent this, Dry Your Dogs Ears within 15 minutes post-swim using a soft towel or a cool-setting hairdryer held at least 12 inches away. For stubborn moisture, use vet-approved drying solutions designed to evaporate water without irritation. These steps disrupt the cycle before infections start. Consistent drying isn’t just routine-it’s a proven way to keep your swim-loving dog healthy, comfortable, and infection-free.

Use This Vet-Approved Vinegar Rinse to Prevent Infections

You’ve already made drying your dog’s ears part of your post-swim routine, and that’s a solid first step-but you can take prevention even further with a simple, vet-approved vinegar rinse. Mix equal parts white vinegar or apple cider vinegar and clean water to create a solution that gently acidifies the ear canal, making it less welcoming to yeast and bacteria. After swimming, fill each ear canal with the rinse, then massage the base for 15–20 seconds to loosen debris and promote gentle cleaning. Let your dog shake their head-this helps remove water in their ears and speeds up drying. This routine reduces the risk of infections and otitis externa caused by trapped moisture. Use it only on healthy Dog’s Ears, never on red, painful, or discharge-filled ears. With consistent use, this vinegar rinse supports long-term ear health.

When to Avoid Home Ear Cleaning: and Why It’s Risky

If your dog’s ears are red, swollen, or tender to the touch, skip the DIY vinegar rinse-cleaning at home could worsen inflammation and push bacteria deeper into the canal, increasing pain and delaying healing. Using home ear cleaners on red or inflamed ears, or when there’s foul-smelling discharge, risks aggravating infections like otitis externa. Never apply DIY vinegar solutions if you suspect a ruptured eardrum; fluids can leak into the middle ear, possibly triggering a middle ear infection or vestibular issues. If your dog shows pain when touching ears-flinching, whining, or head shying-home cleaning risks outweigh benefits. These signs demand prompt veterinary evaluation, not home care. Avoid home rinses altogether if your dog’s already been diagnosed with otitis media or interna. When in doubt, skip the home cleaning and let your vet guide treatment-it’s the safest way to protect your swim-loving dog’s hearing and comfort.

Spot Early Trouble: How to Check Your Dog’s Ears Weekly

Because catching ear issues early can save your dog from discomfort and costly vet bills, make weekly ear checks part of your routine-especially if your pup loves the water. Regular Ear Checks help spot Signs of Ear Infections before they worsen. Lift the ear flap and look for redness, swelling, or foul odor-common clues your dog may be scratching at the ears or shaking their head. Water trapped after swimming boosts infection risk, so always dry your dog’s ears thoroughly. Use a soft, vet-approved wipe to clean only the outer canal. Never insert cotton swabs. For floppy-eared breeds, check twice weekly. Pair this with Regular Veterinary Check-ups to keep your dogs ears healthy long-term.

Why Swimming Triggers Ear Infections in Dogs

Swimming brings joy and exercise for many dogs, but it also sets the stage for ear infections, especially when moisture gets trapped in their uniquely shaped ear canals. Your dog’s ears have a vertical and horizontal canal, making it easy to trap moisture after swimming. That damp environment becomes an ideal breeding ground for bacteria or yeast, especially in floppy-eared breeds like Labradors or Cocker Spaniels. Water from lakes or rivers adds to the risk, carrying more bacteria and allergens than chlorinated pools. When water lingers, it disrupts the outer ear’s natural pH, weakening its defense against microbial growth. Prolonged exposure can lead to chronic otitis externa, an inflammation of the outer ear. The key is acting fast-dry the canal thoroughly after every swim to stop infections before they start.

7 Signs It’s Time to Call the Vet for Ear Care

How do you know when your dog’s post-swim ear care has gone from routine to urgent? Watch for signs like persistent head shaking, ear scratching, or head tilting-these often signal developing ear infections. If you notice redness, swelling, pain, or a foul odor coming from the ear, contact a veterinarian right away. Discharge that’s yellow, brown, or bloody means an active infection likely needs prescription treatment. Don’t wait if your dog yelps or pulls away when you touch their ears-pain is a serious indicator. Previous issues like otitis externa or recurring infections demand immediate professional attention, not home remedies. Chronic ear problems could point to underlying conditions like allergies or hypothyroidism. Early intervention prevents complications, so when in doubt, contact a veterinarian. Stay alert, stay proactive, and keep your swim-loving pup healthy with timely ear care.

On a final note

Keep your dog’s ears dry after every swim-use a soft towel and gently wipe the outer ear, then apply a vet-approved vinegar rinse, like Epi-Otic, to maintain pH balance. Check ears weekly for redness or odor. Avoid cotton swabs. If you spot head shaking, swelling, or discharge, call your vet. Preventive care cuts infections by up to 70%, says real-world testing. Stay consistent, stay proactive.
