Ear Infections in Dogs: Signs, Causes, and When to See Your Vet

Ear infections are one of the most common reasons dogs visit the vet — and they can quickly become painful if left untreated. At Grace Animal Hospital in Holly Springs, we frequently help dogs experiencing ear discomfort, head shaking, and irritation. Knowing what to look for can help you get your pet relief faster.

Signs Your Dog May Have an Ear Infection

Ear infections (also called otitis) often start with subtle symptoms but can escalate quickly. Common signs include:

• Redness inside the ear
• Swelling or inflammation
• Odor coming from the ear
• Head shaking
• Scratching at ears
• Sensitivity or pain when touched

Dogs with ear infections may even resist petting around the head due to discomfort.

If you notice any of these symptoms, it's best to schedule an exam with a veterinarian before the infection worsens.

Types of Ear Infections in Dogs

There are three main types of ear infections, depending on where the inflammation occurs:

Otitis Externa
This affects the outer ear and ear canal. Because dogs have an L-shaped ear canal, debris and moisture can become trapped, making infections more likely.

Otitis Media
This involves the middle ear and can impact balance. Pus and debris can get trapped behind the eardrum.

Otitis Interna
This affects the inner ear, which controls hearing and balance. These infections are more serious and require prompt treatment.

What Causes Ear Infections in Dogs?

Several factors can increase your dog’s risk:

Allergies

Allergies are one of the most common causes. Because the ear canal is lined with skin, inflammation from allergies often leads to infection.

Ear Shape

Dogs with floppy ears or narrow ear canals trap moisture and debris more easily.

Bacteria and Yeast

Normal bacteria and yeast live in dog ears, but inflammation allows them to multiply and cause infection.

Foreign Objects

Grass seeds, debris, or dirt can become lodged in the ear.

Injury or Chronic Infections

Repeated infections can cause long-term damage to the ear canal.

How Veterinarians Diagnose Ear Infections

At Grace Animal Hospital, diagnosing an ear infection includes:

• Reviewing your dog’s medical history
• Examining the ear with an otoscope
• Performing ear cytology (microscope exam)
• Identifying bacteria or yeast

This testing is important because no single medication treats all ear infections — treatment must match the cause.

Treatment for Dog Ear Infections

Treatment may include:

• Ear cleaning
• Antibiotics
• Antifungal medication
• Anti-inflammatory medication
• Pain relief

Follow-up visits are extremely important. Stopping treatment too early can cause the infection to return or worsen.

When Ear Infections Become Chronic

Repeated ear infections can cause:

• Permanent ear canal damage
• Bone infection
• Hearing loss
• Need for surgery

In severe cases, deep ear flushing or advanced imaging may be required.

When to Visit Grace Animal Hospital

You should schedule an appointment if your dog:

• Is shaking their head frequently
• Has red or smelly ears
• Scratches their ears often
• Seems painful when touched
• Has recurring ear issues

Early treatment helps prevent chronic infections and keeps your dog comfortable.
