Summer is here, and while the warm weather means more walks, hikes, and swimming trips with your dog or cat, it also brings a seasonal spike in ear infections. Veterinary clinics report a 30-40% increase in otitis externa cases during the summer months, and the American Veterinary Medical Association (AVMA) identifies heat, humidity, and water exposure as the top three triggers. Here's what every pet owner needs to know about summer ear care and how a simple prevention routine can save your pet from weeks of discomfort.
Why Summer Makes Pet Ears Vulnerable
The anatomy of a dog's ear canal — long, L-shaped, and poorly ventilated — creates a perfect breeding ground for bacteria and yeast when moisture gets trapped. Cats have shorter but equally sensitive ear canals. Summer introduces three specific risk factors:
1. Swimming and Bathing — Water that enters the ear canal during a lake swim, backyard splash session, or post-hike bath doesn't always drain out. Left unchecked, that trapped moisture creates a warm, dark environment where Malassezia yeast and Pseudomonas bacteria thrive. Even indoor cats can be affected if they play near open windows in humid conditions.
2. Heat and Humidity — Dogs that spend time outdoors in hot, humid weather produce more ear wax as a natural response. Excess wax traps debris and provides the organic material microorganisms need to multiply. The AVMA notes that floppy-eared breeds (Labradors, Cocker Spaniels, Beagles) are especially prone because their ear flaps reduce airflow even further.
3. Seasonal Allergens — Summer brings pollen, grass, and dust mites. Allergic reactions cause inflammation inside the ear canal, which narrows the already-tight passage and reduces natural cleaning. Inflamed ears produce more discharge, creating a cycle that leads to infection.
Signs Your Pet Has a Summer Ear Infection
Catching an ear infection early is the best way to avoid a trip to the vet. Watch for these warning signs recommended by veterinary dermatologists.
In Dogs:
• Excessive head shaking or tilting
• Scratching at one or both ears more than usual
• Redness or swelling inside the ear flap
• A foul, yeasty, or musty odor coming from the ear
• Dark brown, yellow, or bloody discharge
• Whining or sensitivity when the ear is touched
• Tilting the head to one side or walking in circles
In Cats:
• Frequent pawing at the ears
• Red or inflamed inner ear
• Black, crumbly discharge (often a sign of ear mites, which spike in summer)
• Holding one ear flat against the head
• Loss of balance or disorientation
If you notice any of these signs, a veterinary exam is the safest next step. However, prevention is far more effective than treatment — and it only takes a few minutes a day.
How to Prevent Summer Ear Infections: A 3-Step Routine
Step 1: Dry Ears After Every Water Exposure
After every swim, bath, or rainy walk, gently dry your pet's outer ear with a soft, clean towel. Do not insert anything deep into the ear canal — you only need to dry what you can see. For dogs that swim frequently, veterinary dermatologists at the American College of Veterinary Dermatology recommend a drying ear rinse after each session.
Step 2: Gentle Weekly Cleaning
Once a week during summer (or after every swim), use a pet-safe ear cleaning wipe to gently remove wax, debris, and moisture from the visible part of the ear. RunyePet Ear Cleaning Finger Wipes are a convenient option — the textured finger-wipe design lets you reach the outer ear canal safely without dropping loose debris inside. Each wipe is pre-moistened with green tea extract, aloe vera, and eucalyptus oil that help dry the canal while soothing irritated skin.
Avoid cotton swabs (Q-tips). The AVMA warns that cotton swabs push debris deeper into the canal and can damage the sensitive lining, making infections more likely rather than less.
Step 3: Monitor Breed-Specific Risk
Not all pets face the same summer ear risk. These breeds need extra vigilance during warm months.
High-risk dogs: Labrador Retrievers, Golden Retrievers, Cocker Spaniels, Basset Hounds, Beagles, Poodles, and any dog with long, floppy ears or narrow ear canals.
High-risk cats: Persians, Himalayans, and other flat-faced breeds have smaller ear openings that trap moisture more easily. Outdoor cats that hunt in tall grass during summer also pick up plant material that can lodge in the ear canal.
If your breed is on this list, consider increasing ear checks to 2-3 times per week during summer.
What NOT to Do for Summer Ear Care
Misinformation about pet ear care is common online. Here are the most dangerous myths to avoid.
Do not pour hydrogen peroxide into the ear to dry it out. Hydrogen peroxide damages healthy tissue and delays healing. It can turn a mild irritation into a full infection.
Do not use baby oil or olive oil to prevent moisture. Oils trap moisture inside the ear rather than repelling it, creating an even better environment for yeast growth.
Do not rely on smell alone. Some early-stage infections have no odor at all. Rely on visual inspection and your pet's behavior, not just smell.
Do not skip indoor cats. Indoor cats are still exposed to summer humidity and seasonal allergens that enter through open windows. Regular gentle cleaning is still recommended.
When to Visit the Vet
Even with the best prevention routine, some pets will develop infections. Schedule a veterinary appointment if:
• Cleaning does not improve redness or discharge within 24 hours
• Your pet is in obvious pain (yelping when touched, avoiding head pets)
• There is blood or pus in the ear
• Your pet develops a head tilt or balance problem
• The ear has a foul smell that does not go away after cleaning
Chronic ear infections can lead to hearing loss, aural hematomas (burst blood vessels in the ear flap that require surgical drainage), or eardrum rupture. Early treatment is essential.
FAQ — Summer Ear Care for Pets
Can I use the same ear cleaning product for my dog and cat?
Most gentle, alcohol-free ear cleaning wipes are safe for both dogs and cats, but check the label. Products with essential oils like tea tree or peppermint can be toxic to cats. RunyePet Ear Cleaning Finger Wipes are formulated for both species — the green tea and aloe vera formula is gentle enough for cats while effective for dogs.
How often should I clean my pet's ears in summer?
For most pets, once per week during summer is sufficient. If your dog swims daily, clean after every swim. For cats, once every two weeks is usually enough unless they show signs of wax buildup.
Is it normal for my dog's ears to smell a little in summer?
A mild, waxy smell is normal, especially in floppy-eared breeds during humid weather. A strong, fishy, or sweet yeasty odor is not normal and suggests an infection that needs treatment.
Does swimming in chlorinated pools prevent ear infections?
Chlorine kills some bacteria but also irritates the sensitive lining of the ear canal, which can make infections more likely. Always rinse and dry your pet's ears after pool swimming just as you would after lake or ocean swimming.
Can cats get swimmer's ear?
Yes. While most cats avoid water, cats that are bathed at home or play near water bowls can develop moisture-related ear irritation. Dry their ears gently after any water exposure.
Conclusion
Summer should be about fun, not vet visits. A simple prevention routine — dry after swimming, clean weekly with pet-safe ear cleaning wipes, and monitor your pet's ears for early warning signs — can prevent the vast majority of summer ear infections. As recommended by the American Veterinary Medical Association, proactive ear care during warm months is one of the simplest things you can do for your pet's long-term health.
