Dog Ear Infections Understanding Symptoms, Causes & Treatment

Dog ear infections are common and can quickly become painful without proper treatment. At Paw Haven Animal Hospital, we help identify the cause of your dog’s ear infection, provide targeted care, and support long-term ear health to reduce discomfort and repeat flare-ups.

What Are the Common Signs of Ear Infections in Dogs?

The most common signs of a dog ear infection include head shaking, ear scratching, rubbing the face, redness inside the ear, discharge, and an unpleasant odor. Some dogs may also seem sensitive around the ears or show discomfort when touched. Early treatment helps prevent the infection from becoming more painful or harder to treat.

What Causes Dog Ear Infections?

Ear infections often develop when inflammation changes the environment inside the ear canal and allows yeast or bacteria to overgrow. Allergies are one of the most common underlying causes, but moisture, ear mites, excess hair in the ear canal, floppy ears, narrow ear canals, and some endocrine conditions may also contribute.

Many recurrent ear infections are linked to underlying allergies or chronic inflammation.

How We Diagnose Ear Infections

A proper diagnosis starts with a gentle ear exam. Our team may use an otoscope to examine the ear canal and, when possible, the eardrum. We may also collect a small sample for cytology, which helps identify whether yeast, bacteria, or another issue is involved so treatment can be tailored to your dog’s needs.

Because ear infections can be painful, we take a careful approach and avoid forcing the exam if your dog is too uncomfortable.

How Ear Infections Are Treated

Treatment depends on what is causing the infection. We may clean the ear thoroughly, remove debris, prescribe targeted ear medication, and address inflammation. Some dogs may also need oral medication such as antibiotics, anti-inflammatories, or short-term steroids. For dogs with repeat infections, treating the underlying cause is just as important as clearing the current infection.

Ear cleaning

May help ease chronic pain and discomfort.

Targeted medication

Supports movement for dogs with stiffness or joint issues.

Inflammation relief

Can help calm inflammation and improve comfort.

Long-term management for repeat infections

Often used to support healing after injury or illness.

Why Early Treatment Matters

When ear infections are left untreated, they can become more severe and may lead to complications such as chronic pain, ear hematomas from intense head shaking, and temporary or permanent hearing loss. Prompt care helps protect your dog’s comfort and may reduce the risk of repeat problems.

Can ear infections come back?

Yes. Dogs with allergies or chronic inflammation may be more likely to experience repeat ear infections, which is why accurate diagnosis and follow-up care are important.

When should I call the vet?

If your dog is shaking their head, scratching their ears, showing pain, or has redness, discharge, odor, or swelling around the ear, schedule an exam as soon as possible.

Frequently asked

Can dog ear infections go away on their own?

Dog ear infections usually need veterinary treatment. Without proper care, the infection may become more painful, spread deeper into the ear, or lead to repeat flare-ups. Paw Haven can check the ear and recommend the right treatment based on the cause.

Why does my dog keep getting ear infections?

Repeat ear infections are often linked to allergies, chronic inflammation, trapped moisture, floppy ears, narrow ear canals, excess hair, or underlying health conditions. Getting the right diagnosis helps reduce the chance of recurring infections.

How does Paw Haven test for a dog ear infection?

The veterinary team may examine your dog’s ear with an otoscope and collect a small sample for cytology. This helps identify whether yeast, bacteria, or another issue is causing the infection, so treatment can be more targeted.

What happens if a dog ear infection is left untreated?

Untreated ear infections can lead to chronic pain, stronger inflammation, ear hematomas from head shaking, and temporary or permanent hearing loss. Early treatment helps protect your dog’s comfort and long-term ear health.
