Dog Scratching Ear Whining
By Dr. Zubair Khalid, DVM, MS, PhD ·
Key Takeaways
- The combination of ear scratching and whining in dogs is a strong indicator of moderate to severe ear discomfort, frequently stemming from infections (bacterial or yeast), allergies, or the presence of foreign bodies like grass awns.
- Diagnostic evaluation by a veterinarian is crucial, often involving otoscopic examination and cytology of ear discharge to identify causative agents such as bacteria, yeast, or mites, guiding targeted therapeutic interventions.
- Common therapeutic strategies include medicated ear cleaners, topical antibiotic, antifungal, or anti-inflammatory drops/ointments, and potentially oral medications or allergy management protocols.
- Risk factors for ear issues include floppy ear conformation and frequent water exposure, while allergies can present with concurrent symptoms like paw licking or face rubbing, necessitating a holistic diagnostic approach.
- Home care should be limited to gentle outer ear cleaning with veterinarian-approved solutions and preventing self-trauma with an Elizabethan collar; insertion of any objects into the ear canal is contraindicated due to risk of eardrum damage or pushing debris deeper.
- Prompt veterinary attention is warranted for signs of severe inflammation (redness, swelling, bleeding), systemic illness (lethargy, fever), suspected foreign objects, or neurological signs (head tilting, loss of balance) suggestive of inner ear involvement.
If your dog is scratching at an ear and whining in discomfort, you are likely seeing a clear sign of ear irritation or infection. Ear problems are very common in dogs, and the combination of scratching and whining often means the discomfort is moderate to severe. This article will help you understand what might be causing this behavior, what you can do at home, and when a vet visit is necessary.
Quick Q&A: Common Questions
Question: Why is my dog scratching his ear and whining?
Answer: Scratching and whining usually indicate pain or intense itching in the ear. The most common causes are ear infections (bacterial or yeast), allergies, or a foreign object like a grass awn. Whining suggests the irritation is severe enough to cause distress, and prompt veterinary evaluation is recommended to prevent complications like a ruptured eardrum or chronic infection.
Common Causes of Ear Scratching and Whining
Ear Infections
Infections are the leading cause. Bacteria or yeast overgrow in the warm, moist environment of the ear canal. Look for redness, swelling, discharge (dark brown, yellow, or pus-like), and a foul odor. Dogs with floppy ears or those that swim frequently are at higher risk.
Allergies
Allergic skin disease (from food, pollen, dust mites) often manifests in the ears. Inflammation leads to itching, and secondary infections often follow. Allergies may also cause paw licking, face rubbing, or recurrent ear problems.
Foreign Objects
Grass awns, foxtails, or small debris can lodge deep in the ear canal, causing acute pain and scratching. If your dog suddenly starts shaking the head and whining after being outdoors, suspect a foreign object.
Ear Mites
These tiny parasites cause intense itching, especially in puppies. Look for dry, dark, crumbly discharge that resembles coffee grounds. Ear mites are highly contagious among pets but less common in adult dogs.
Trauma or Growths
A wound, hematoma (blood-filled swelling from shaking), or a polyp/tumor in the ear canal can also cause discomfort. Whining may be more pronounced if there is pressure or bleeding.
Home Care Steps to Try (Before the Vet)
Do not insert anything into the ear canal. This includes cotton swabs, which can push debris deeper and damage the eardrum.
- Gentle cleaning of the outer ear: Use a veterinarian-recommended ear cleaner on a cotton ball or soft cloth to wipe away visible discharge from the ear flap and the opening of the canal. Never probe inside.
- Prevent further trauma: If your dog is shaking its head violently, try to calm it. A head wrap or an Elizabethan collar may be needed to stop scratching until you see the vet.
- Check for foreign objects: Gently lift the ear flap and look for anything obvious like a grass awn. If you see one, do not attempt removal; leave it to your vet.
- Avoid home remedies: Do not put alcohol, hydrogen peroxide, or essential oils in the ear. These can cause severe pain and worsen inflammation.
When to See the Vet
Anytime your dog is scratching an ear and whining, a veterinary visit is advisable. Immediate attention is needed if:
- The ear is very red, swollen, or bleeding.
- Your dog seems lethargic or has a fever.
- You see a foreign object but cannot safely remove it.
- The whining is constant and accompanied by head tilting or loss of balance (possible inner ear involvement).
What to Expect at the Vet
The veterinarian will perform a thorough ear exam using an otoscope to look deep into the canal. They may take a sample of discharge to examine under a microscope (cytology) to identify bacteria, yeast, or mites. This determines the correct treatment.
Treatment often includes:
- A medicated ear cleaner to flush the ear.
- Topical drops or ointment (antibiotic, antifungal, or anti-inflammatory).
- Oral medications or allergy therapy if needed.
- In severe cases, sedation for a deep cleaning or to remove a foreign object.
Prevention Tips
- Dry ears after swimming or baths. Use a cloth to gently dry the outer ear and a drying solution if recommended.
- Regular ear checks. Look for redness, odor, or discharge once a week, especially in floppy-eared breeds.
- Manage allergies. Work with your vet on a food trial or allergy medications to reduce inflammation.
- Avoid irritants. Keep your dog away from fields with foxtails or burrs during walks.
- Routine cleaning. Use a vet-approved ear cleaner only as directed; overcleaning can disrupt the ear's natural balance.
Conclusion
When your dog is scratching an ear and whining, it is a clear signal that something is wrong. Ear infections, allergies, foreign objects, and mites are common culprits. While gentle outer ear cleaning can help temporarily, most cases require veterinary treatment to resolve the pain and prevent complications. Prompt care leads to a happier, more comfortable dog.
