Beyond the Head Tilt: 8 Signs Your Dog Might Have an Ear Infection

That adorable head tilt your dog does might usually mean they’re listening carefully, but sometimes it’s a sign that something is wrong. Dog ear infections are one of the most common conditions veterinarians treat, and they can cause significant discomfort if left unaddressed. The tricky part is that dogs can’t tell us when their ears hurt, so learning to recognize the signs of a dog ear infection is one of the most important things you can do as a pet owner. Here are eight signs your dog might have an ear infection and everything you need to know to get them the help they need.

 

 

Understanding Dog Ear Infections

A dog ear infection, medically known as otitis externa (outer ear) or otitis media/interna (middle or inner ear), occurs when the ear canal becomes inflamed and infected. The warm, moist environment of a dog’s ear canal creates ideal conditions for bacteria, yeast, and other pathogens to thrive, especially in dogs with floppy ears, dogs who swim frequently, or dogs with underlying allergies. Without treatment, ear infections can become chronic, spread deeper into the ear, and lead to lasting damage to hearing and balance.

What Causes Dog Ear Infections?

Ear infections in dogs are typically caused by bacteria or yeast, and sometimes both at the same time. Common contributing factors include moisture trapped in the ear canal, allergies (both food and environmental), excessive ear wax buildup, ear mites, foreign objects, or underlying hormonal conditions like hypothyroidism. Identifying the root cause is key to effective treatment, which is why a veterinary exam and ear swab are so important.

8 Signs Your Dog Has an Ear Infection

Dog ear infections rarely go from nothing to severe overnight. Most develop gradually, which means early detection can make treatment faster and more effective. Watch for these eight warning signs.

Head Shaking

One of the most noticeable early signs of a dog ear infection is frequent and vigorous head shaking. Your dog is trying to relieve discomfort or dislodge something that feels wrong inside the ear. While dogs shake their heads from time to time, repeated or forceful head shaking (particularly if it’s a new behavior) is worth investigating.

Scratching or Pawing at the Ear

If your dog is frequently scratching at or around their ears, or rubbing their head against furniture, the floor, or your legs, they may be trying to relieve the itch and irritation caused by an ear infection. Persistent scratching can also lead to secondary problems, including broken skin, abrasions, and self-inflicted wounds around the ear area.

Redness and Swelling

Take a moment to gently look inside your dog’s ear flap and the entrance to the ear canal. Healthy dog ears are typically pale pink and free of debris. If you notice redness, swelling, or inflammation, these are classic signs of a dog ear infection. The skin inside the ear may look irritated or raw.

Discharge from the Ear

Discharge is a significant indicator of an ear infection in dogs. You might notice a dark brown or black waxy buildup (often associated with yeast), yellow or green discharge (often bacterial), or a mix of the two. Any unusual discharge from your dog’s ear should be evaluated by a veterinarian, as the type of discharge can help guide diagnosis and treatment.

Unpleasant Odor

Healthy dog ears have very little noticeable scent. A foul, musty, or sour smell coming from your dog’s ears is a hallmark sign of infection. The odor is caused by the bacteria or yeast proliferating in the warm, moist ear canal. If your dog’s ears smell off and you can’t remember a time they smelled this way before, don’t ignore it.

Sensitivity or Pain When the Ear Is Touched

Does your dog pull away, whine, or snap when you touch their ears? While some dogs are simply sensitive about having their ears handled, a sudden change in behavior, especially if your dog has always tolerated ear touching, can indicate pain caused by an ear infection. Inflammation and infection make the ear canal sensitive and sore, and your dog is simply communicating their discomfort.

Head Tilt or Loss of Balance

A persistent head tilt, where your dog holds their head cocked to one side even when resting, can be a sign of a middle or inner ear infection. Infections that penetrate deeper into the ear can affect the vestibular system, which controls balance. Along with a head tilt, you may notice your dog stumbling, circling, or appearing disoriented. These signs require prompt veterinary attention.

Crusting Around the Ear or Hair Loss

Chronic scratching and inflammation can lead to crusting of the skin around the outer ear and hair loss in the area. These changes happen over time and signal that an ear infection has been developing for a while. If you notice these physical changes, your dog likely needs veterinary care for an infection that has progressed beyond its early stages.

Which Dogs Are Most Prone to Ear Infections?

While any dog can develop an ear infection, some are at higher risk than others. Dogs with long, floppy ears like Basset Hounds, Cocker Spaniels, and Labrador Retrievers have limited air circulation in the ear canal, creating a warm, moist environment where bacteria and yeast thrive. Dogs who swim regularly are also at elevated risk, as water trapped in the ear canal is a common trigger. Additionally, dogs with skin allergies frequently experience recurring ear infections as part of their broader allergic response.

What Happens If a Dog Ear Infection Goes Untreated?

Untreated ear infections can progress from uncomfortable to serious. A simple outer ear infection can spread to the middle and inner ear, causing chronic pain, permanent hearing loss, and severe vestibular problems. In very advanced cases, surgical intervention may be necessary. The earlier an ear infection is caught and treated, the better the outcome for your dog, both in terms of recovery and preventing recurrence.
