As warmer weather arrives, many dogs head to the water for swimming, splashing, and playing. Whether it is a trip to the beach, a dip in the pool, or simply playing with the garden hose, water activities are enjoyable — but they can also pose a risk to your dog's ear health. Water trapped in the ear canal can lead to discomfort and infection if not properly managed. Understanding what swimmer's ear is, how to recognize it, and how to prevent it can help keep your dog's ears healthy throughout the season and year-round.
What Is Dog Swimmer's Ear?
Dog swimmer's ear, also categorized as a type of otitis externa, is an infection of the outer ear canal that often occurs when water gets trapped inside the ear. A moist environment creates the perfect breeding ground for bacteria and yeast, leading to an ear infection. Unlike humans, dogs have an L-shaped ear canal, which makes it harder for water to escape once it gets inside. This trapped moisture causes irritation and inflammation, setting the stage for infection to develop.
Dogs that frequently swim or bathe are at higher risk of developing swimmer's ear. However, it is not limited to avid swimmers — any dog can get water in their ears during routine activities like playing in the rain or being bathed. Knowing how swimmer's ear develops is the first step in protecting your dog from this uncomfortable and potentially painful condition.
Signs of Water Trapped in Your Dog's Ear
Recognizing the early signs that your dog has water in their ear can help you address the issue before it progresses to a full infection. One of the most common indicators is frequent head shaking or tilting. Dogs will often shake their heads vigorously in an attempt to dislodge trapped water. If you notice your dog doing this after swimming or bathing, it is a good sign that water may be trapped in the ear canal.
Scratching at the ears is another common sign. If your dog is constantly pawing at their ears or rubbing them against furniture or the ground, it could indicate discomfort from trapped moisture. You may also notice behavioral changes such as increased irritability or reluctance to have their ears touched. An unusual odor coming from the ear is often an early warning sign that bacteria or yeast have begun growing in the moist environment.
Symptoms of Swimmer's Ear Progressing to Infection
When water remains trapped in the ear, symptoms can escalate beyond head shaking and scratching. Redness and swelling in the ear canal indicate that inflammation has developed in response to the trapped moisture. This inflammation can cause significant discomfort.
Discharge from the ear is another symptom to watch for. This discharge can range from clear fluid to yellow or green pus depending on the severity of the infection. If you notice any discharge, consult your veterinarian, as it likely indicates that the trapped water has led to an active infection.
Pain and sensitivity are also common as the condition progresses. Your dog may whine or yelp when their ears are touched or when they scratch at them. They may also show signs of general discomfort such as decreased appetite or lethargy. These symptoms indicate a more serious issue that should be addressed promptly to prevent complications.
Can Water Cause Ear Infections in Dogs?
Yes. Moisture trapped in the ear canal creates an ideal environment for bacteria and yeast to thrive. When water gets trapped, the resulting inflammation compromises the natural defenses of the ear, allowing bacteria and yeast to multiply unchecked and leading to infection.
Dogs with floppy ears, such as Cocker Spaniels and Basset Hounds, are particularly susceptible to water-related ear infections. Their ear flaps cover the ear canal, creating a dark, warm, and moist environment that promotes microbial growth. Dogs with allergies or existing skin conditions are also at higher risk, as these conditions can further weaken the ear's defenses against infection.
It is important to address any signs of discomfort or infection early. Left untreated, ear infections can lead to chronic issues including hearing loss and persistent pain. Regular ear checks and proper ear care are essential in preventing these infections, especially for dogs that enjoy swimming or water play.
How to Protect Your Dog From Swimmer's Ear
Preventing swimmer's ear involves a combination of proactive measures and regular ear care. Ear plugs or ear wraps can help keep water out of the ear canal during swimming and bathing. Ear wraps tend to be a more practical option, as most dogs will not tolerate ear plugs.
After your dog has been in the water, dry their ears thoroughly. Use a soft, dry towel to gently pat the ears dry, and consider using an ear drying solution like OticBliss Cleansing and Drying Ear Flush or OticBliss Cleansing and Drying Ear Wipes. These products are designed to evaporate excess moisture and help prevent the buildup of bacteria and yeast.
Regular ear cleaning is another important step. Use a veterinarian-recommended ear cleaner to remove dirt, ear wax, and debris from your dog's ears. Be gentle and avoid inserting anything deep into the ear canal, as this can cause injury. Consistent ear cleaning helps maintain a healthy environment in the ear and reduces the risk of infections, especially in susceptible breeds.

Keep an eye on your dog's ears and be vigilant for any signs of discomfort, irritation, or infection. Early detection and treatment are key to preventing serious issues. If you notice any symptoms, consult your veterinarian for advice and appropriate treatment.
Other Causes of Ear Infections in Dogs
While water is a common cause of ear infections, other factors can contribute to the condition. Allergies are a major factor — dogs can be allergic to pollen, dust mites, and certain foods, and these allergies can cause inflammation and excess ear wax production, increasing the risk of infection.
Parasites such as ear mites can also cause ear infections. These tiny organisms irritate the ear canal and cause inflammation, which can lead to secondary bacterial or yeast infections. Regular veterinary checkups and maintaining good ear hygiene can help prevent infestations and subsequent infections.
Foreign objects are another common cause, particularly in dogs that spend a lot of time outdoors. Small objects like grass seeds can become trapped in the ear and cause irritation that creates an environment conducive to infection. Regularly inspecting your dog's ears and removing any visible debris can help prevent these issues.
Underlying health conditions such as hypothyroidism or autoimmune diseases can also predispose dogs to ear infections. These conditions can affect the body's ability to fight off infections and maintain healthy skin and ear tissue. If your dog experiences chronic or recurring ear infections, consult your veterinarian to rule out any underlying health problems that may be contributing to the issue.
