# [Dog Scratching Ears](/knowledge/veterinary-medicine/behavior/dog-scratching-ears) Shaking Head


## Key Takeaways

- Persistent ear scratching and head shaking in dogs are most commonly indicative of otitis externa, often caused by bacterial or yeast overgrowth, or allergic dermatitis (environmental or food-related).
- Diagnostic evaluation by a veterinarian is crucial, typically involving otoscopic examination to visualize the ear canal and cytology to identify causative agents like bacteria, yeast, or parasites (e.g., ear mites).
- Foreign bodies, such as grass awns, can cause acute, intense irritation and necessitate gentle removal, potentially under sedation or anesthesia.
- Management strategies include veterinarian-prescribed topical medications (antibiotics, antifungals, anti-inflammatories) for infections, and addressing underlying allergies through dietary modification or immunotherapy.
- Preventive measures involve regular ear checks, thorough drying of ears after water exposure, and prompt management of identified allergens to mitigate recurrence.

If you have noticed your dog repeatedly scratching at their ears or shaking their head with unusual intensity, you are not alone. This behavior is one of the most common reasons pet owners seek veterinary advice. While an occasional scratch or shake is normal, persistent or frantic activity often signals an underlying issue that requires attention.

Understanding why dogs scratch their ears and shake their heads is the first step toward providing relief. This article will walk you through the possible causes, safe home care strategies, what to expect at the vet, and how to prevent future problems.

## Quick Q&A: Common Questions

**Question:** Why is my dog scratching their ears and shaking their head so much?

**Answer:** The most common reasons are ear infections (caused by bacteria or yeast), allergies (environmental or food), or a foreign object stuck in the ear canal. These irritants trigger inflammation and discomfort, prompting your dog to scratch and shake in an attempt to relieve the sensation. A veterinary exam is the best way to pinpoint the exact cause and start effective treatment.

## Common Causes of Ear Scratching and Head Shaking

When a dog persistently scratches their ears or shakes their head, several conditions could be at play. The most frequent culprits fall into a few key categories.

### Ear Infections (Otitis Externa)

Infections of the outer ear canal are the leading cause of ear discomfort in dogs. Bacteria and yeast thrive in the warm, moist environment of the ear, especially when normal defenses are compromised. Signs include redness, swelling, a foul odor, and discharge that may be brown, yellow, or bloody. Dogs with floppy ears, such as Cocker Spaniels and Labrador Retrievers, are more prone to these infections.

### Allergies

Allergies to environmental triggers (pollen, dust mites, mold) or food ingredients (commonly chicken, beef, dairy, or grains) often manifest as ear inflammation. In allergic dogs, the ear lining becomes swollen and itchy, setting the stage for secondary infections. If your dog also licks their [paws](/knowledge/veterinary-medicine/clinical-methods/paws) or has skin redness, allergies are a strong possibility.

### Foreign Bodies

Grass awns, foxtails, seeds, or small debris can become lodged deep in the ear canal. These foreign objects cause intense irritation and pain, leading to frantic head shaking and scratching. This is especially common in dogs that spend time in tall grass or wooded areas.

### Ear Mites

Ear mites are tiny parasites that infest the ear canal, causing severe itching. They are more common in puppies but can affect dogs of any age. A telltale sign is a dark, crumbly discharge that resembles coffee grounds.

### Moisture or Swimming

Dogs that swim frequently or are bathed without proper ear drying can develop "swimmer's ear," a mild infection or irritation caused by trapped moisture. This creates a perfect breeding ground for bacteria and yeast.

## Safe Home Care: What You Can Do

Before your vet appointment, there are a few things you can try to keep your dog comfortable. Never insert anything into the ear canal, including cotton swabs, as this can push debris deeper or damage the eardrum.

- **Inspect the ear gently.** Look for redness, swelling, discharge, or visible debris. If you see a foreign object, do not attempt to remove it yourself.
- **Clean the outer ear only.** Use a veterinarian-recommended ear cleaner on a cotton ball or soft cloth. Wipe away discharge from the ear flap and the visible part of the canal entrance.
- **Prevent further irritation.** Try an Elizabethan collar (cone) if your dog will not stop scratching, as excessive scratching can cause hematomas (blood blisters) on the ear flap.
- **Keep ears dry.** After baths or swimming, gently dry the outer ear with a soft towel.

## What to Expect at the Veterinarian

A thorough ear exam is essential for an accurate diagnosis. Your veterinarian will likely perform the following steps.

### Otoscopic Examination

Using an otoscope, the vet will look deep into the ear canal to check for foreign bodies, inflammation, discharge, and the condition of the eardrum. This is the most important part of the exam.

### Ear Cytology

A sample of ear discharge is taken and examined under a microscope. This quick test identifies whether the infection is bacterial, yeast, or a mix of both, and helps the vet choose the most effective medication.

### Treatment Options

Treatment depends on the underlying cause. For infections, your vet will prescribe medicated ear drops or ointments, often containing antibiotics, antifungals, and anti-inflammatories. For allergies, they may recommend dietary changes, allergy testing, or medications like antihistamines or steroids. Foreign bodies are gently removed under sedation or anesthesia.

## Preventing Future Ear Problems

Once your dog's ears are healthy, you can take steps to reduce the likelihood of recurrence.

- **Check ears weekly.** Look for redness, discharge, or odor. Early intervention prevents minor issues from escalating.
- **Dry ears after swimming or baths.** Use a gentle ear drying solution if your dog is prone to moisture-related problems.
- **Manage allergies.** Work with your vet to identify and avoid triggers. This may include hypoallergenic diets, regular bathing, or allergy medications.
- **Avoid overcleaning.** Cleaning too often or with harsh products can strip protective oils and irritate the ear lining.

By staying observant and addressing ear issues promptly, you can help your dog avoid the discomfort and complications associated with chronic ear problems. If scratching and head shaking persist for more than a day or two, a veterinary visit is the safest and most effective path to relief.
