Dog Shaking Head Rubbing Ear

It can be worrying to see your dog repeatedly shaking their head and rubbing at an ear. While an occasional head shake is normal, persistent or intense behavior often signals discomfort or an underlying health issue. This article explains the most common reasons for a dog shaking head and rubbing ear, what you can do at home, and when a trip to the veterinarian is necessary.

Quick Q&A: Common Questions

Question: Why is my dog shaking their head and rubbing their ear?

Answer: This behavior usually indicates irritation or pain in the ear canal. Common causes include ear infections (bacterial or yeast), ear mites, allergies, or a foreign object like a grass awn. The head shaking is an instinctive attempt to dislodge the irritant, while rubbing provides temporary relief.

Common Causes of Head Shaking and Ear Rubbing

Understanding the root cause is the first step to helping your dog. Here are the most frequent culprits.

Ear Infections (Otitis Externa)

Inflammation of the outer ear canal is a leading cause. Infections can be bacterial or yeast-based. Look for redness, swelling, a foul odor, or discharge that is yellow, brown, or black. Dogs with floppy ears, like Cocker Spaniels or Basset Hounds, are more prone.

Ear Mites

These tiny parasites are highly contagious, especially among puppies or multi-pet households. They cause intense itching. You might see a dark, crumbly discharge that looks like coffee grounds. Your dog may shake their head vigorously and rub their ears against furniture or the floor.

Allergies

Environmental allergies (pollen, dust mites) or food allergies can trigger inflammation in the ears. This is often a chronic issue. Your dog might also show other signs like itchy skin, paw licking, or recurrent ear infections.

Foreign Objects

Grass awns, foxtails, or small seeds can become lodged in the ear canal. This is a common problem in dogs that spend time outdoors in grassy or weedy areas. The sudden onset of head shaking and rubbing is a strong clue.

Other Causes

Less common causes include ear polyps or tumors, aural hematomas (a blood blister on the ear flap from trauma), or a skin condition like seborrhea. If the behavior persists despite treatment, your vet may investigate these possibilities.

What to Do at Home (Before the Vet)

While you should not delay a vet visit, you can provide safe, temporary relief and assess the situation.

• Inspect the Ear Gently: Lift the ear flap and look for obvious redness, discharge, or a visible foreign object. Do not insert anything into the ear canal.
• Clean the Outer Ear: Use a veterinarian-recommended ear cleaner on a cotton ball or soft cloth. Wipe only the visible part of the ear flap and the opening of the ear canal. Never use cotton swabs (Q-tips) as they can push debris deeper.
• Prevent Further Irritation: Keep your dog from scratching excessively by using an Elizabethan collar (cone) if needed. This prevents aural hematomas from forming.
• Avoid Home Remedies: Do not put any oils, hydrogen peroxide, or vinegar into the ear. These can worsen inflammation or damage the delicate ear lining.

What to Expect at the Vet

A veterinary visit is essential for proper diagnosis and treatment. Here is what typically happens.

The Examination

The vet will use an otoscope to look deep into the ear canal. This allows them to see the eardrum, check for foreign objects, and assess the severity of the infection. They will also examine the rest of your dog for signs of allergies or other conditions.

Diagnostic Tests

• Ear Cytology: A swab of the ear discharge is placed on a slide and stained. This test identifies bacteria, yeast, or mites under a microscope. It guides the choice of medication.
• Culture and Sensitivity: If the infection is severe or recurrent, a culture may be done to identify the specific bacteria and which antibiotics will work best.

Treatment Options

Treatment depends on the diagnosis.

• Ear Infections: Typically treated with topical ear drops or ointments containing antibiotics, antifungals, and anti-inflammatories. Severe cases may require oral medications.
• Ear Mites: Prescription topical medications are highly effective. All pets in the household may need treatment.
• Allergies: Management may include dietary changes, allergy medications, or immunotherapy (allergy shots).
• Foreign Objects: The vet will remove the object, often under sedation or anesthesia.

Prevention Tips

Preventing ear problems can save your dog from discomfort and you from repeated vet visits.

• Regular Ear Checks: Make ear inspection part of your weekly grooming routine. Look for redness, odor, or discharge.
• Keep Ears Dry: After baths or swimming, gently dry your dog's ears with a soft towel. You can also use a drying ear cleaner.
• Proper Cleaning: Clean your dog's ears only when needed, using a vet-approved solution. Over-cleaning can disrupt the ear's natural defenses.
• Manage Allergies: Work with your vet to identify and manage underlying allergies. This can significantly reduce the frequency of ear infections.
• Trim Ear Hair: For dogs with heavy hair in the ear canal, ask your groomer or vet to trim it. This improves air circulation and reduces moisture.

If your dog is shaking their head and rubbing their ear, do not ignore it. Prompt attention can prevent complications like a ruptured eardrum or a chronic, painful condition. Your veterinarian is your best partner in keeping your dog comfortable and healthy.
