Swimmer’s Ear in Dogs – Vet Prevention and Care Tips for 2025 🌊🐶🦻

As summer rolls in, many dog lovers take to the beach, lakes, or backyard pools with their canine companions. While water play is fantastic enrichment, it can also come with a hidden risk: swimmer’s ear. In this 2025 veterinary guide, Dr Duncan Houston explains what swimmer’s ear is in dogs, how to tell it apart from other ear infections, and the best strategies for prevention and treatment. 🐾☀️

🔍 What Is Swimmer’s Ear in Dogs?

Swimmer’s ear is the informal term for otitis externa—inflammation of the outer ear canal—triggered by water exposure. When water, especially if contaminated, gets trapped in your dog’s ear canal, it creates a warm, dark, moist environment perfect for bacterial overgrowth. 🦠🌡️

🩺 Common Signs of Swimmer’s Ear

Unlike humans, dogs can’t tell you their ears feel blocked or painful—but they’ll show signs, including:

• 🐾 Head shaking
• 👂 Pawing at the ears
• 🛋️ Rubbing ears on furniture or carpet
• 📈 Restlessness or whining
• ⚠️ Twitching or sensitivity near the ears

🔄 Why Do Some Dogs Get It and Others Don’t?

Not every swimming dog develops ear infections. Dogs that do typically have underlying conditions such as:

• 🌿 Environmental allergies (e.g., grass, weeds, pollen)
• 🥗 Food allergies
• 🦟 Ear mites or parasites
• 🔬 Endocrine or immune system disorders
• 🎈 Growths or tumors in the ear canal

These conditions create an already inflamed or unbalanced ear environment. Add in moisture, and you've got the perfect storm for an infection. 🌧️🔥

📋 Case Insight: Why Some Labradors Get Ear Infections After Swimming

For example, many Labrador retrievers are water lovers—but only some end up with infections. That’s because those with allergies or ear inflammation are primed to develop infections. A classic Labrador with seasonal allergies may only need one swim to trigger an ear flare-up. 🧬🐕‍🦺

🧠 Swimmer’s Ear vs. Allergy-Driven Ear Infections

How can you tell if it’s truly swimmer’s ear or something deeper?

• 🤔 Does your dog get ear infections even when not swimming?
• 😣 Does your dog scratch, lick, or chew excessively?
• 💥 Has your dog had skin infections too?

If yes, it's likely that swimming is not the root cause but an aggravating factor of an already sensitive system.

🧴 How to Prevent Swimmer’s Ear

Simple steps after every swim or bath can go a long way:

• 🧼 Use vet-recommended ear drying solutions after swimming
• 🧽 Gently dry ears with soft cotton balls (never use Q-tips!)
• 👂 Monitor for early signs of irritation like redness or odor
• 📆 Regular ear checks and grooming, especially during allergy seasons

💊 Treatment Options

If your dog develops swimmer’s ear, see your vet. Treatment may include:

• 🧫 Ear swabs and cytology to identify the specific infection
• 💊 Topical medications (antibiotic, antifungal, steroid)
• 🧪 Allergy evaluation and long-term management if infections recur

🏖️ When to Skip the Swim

If swimmer’s ear becomes a regular issue, you might need to limit water exposure until the underlying cause is addressed. This is especially true during peak allergy seasons. 🐶🚫🌊

🧠 Additional Tips

• 🌞 Protect sun-sensitive dogs with SPF shirts
• 🧬 Consider allergy testing for dogs with repeated infections
• 🛁 Rinse ears with clean water post-swim to reduce chlorine or lake bacteria
