Dog Scratching Ear And Making Noise
By Dr. Zubair Khalid, DVM, MS, PhD ·
Key Takeaways
- Persistent ear scratching accompanied by vocalizations (whining, whimpering) or rhythmic thumping indicates discomfort and warrants investigation, often stemming from otitis externa, otodectes infestation, or foreign body presence.
- Common etiologies for these clinical signs include bacterial or yeast infections (otitis media/externa), allergic dermatitis (environmental or food-induced), parasitic infestations (Otodectes cynotis), or physical obstruction by foreign bodies like grass awns.
- Diagnostic evaluation by a veterinarian typically involves otoscopic examination to visualize the ear canal and tympanic membrane, coupled with cytology of ear discharge to identify causative agents such as bacteria, yeast (e.g., Malassezia pachydermatis), or mites.
- Therapeutic interventions are etiology-dependent, ranging from topical antimicrobial and antifungal ear preparations for infections, antiparasitic medications for mites, to surgical or manual removal of foreign objects, often requiring sedation.
- Prevention strategies include regular, gentle cleaning of the external ear canal with vet-approved solutions, thorough drying after water exposure to mitigate moisture-related infections, and proactive management of underlying allergies through dietary modification or pharmacotherapy.
- Red flags necessitating immediate veterinary attention include significant swelling, erythema, purulent or bloody discharge, a foul odor, neurological signs (head tilt, ataxia), or persistent, severe discomfort unresponsive to initial home care.
When your dog repeatedly scratches at one or both ears while also whining, whimpering, or producing a rhythmic thumping sound, it is a clear sign of discomfort. This behavior often indicates an underlying issue that requires attention. Understanding the potential causes and knowing when to seek professional help can make a significant difference in your dog's comfort and health.
Quick Q&A: Common Questions
Question: Why is my dog scratching their ear and making noise?
Answer: The most common reasons include ear infections, allergies, ear mites, or a foreign object lodged in the ear canal. The noise often comes from the dog shaking its head vigorously, causing the ear flaps to slap against the head, or from vocalizations due to pain or irritation.
Common Causes of Ear Scratching and Noise
Identifying the root cause is the first step in helping your dog. The sound you hear may be a combination of scratching, head shaking, and vocal distress.
Ear Infections
Bacterial or yeast infections are among the most frequent culprits. They cause inflammation, discharge, and intense itching. Dogs with floppy ears or those that swim frequently are especially prone. The infection can produce a foul odor and may lead to a dark, waxy buildup.
Allergies
Environmental allergens (pollen, dust mites) or food sensitivities can trigger inflammation in the ear canal. This often results in red, itchy ears that the dog scratches persistently. Secondary infections frequently develop because the scratching damages the skin.
Ear Mites
These tiny parasites are highly contagious and cause severe itching. You might notice a dry, coffee-ground-like discharge. Ear mites are more common in puppies but can affect dogs of any age. The scratching is often accompanied by head shaking.
Foreign Objects
Grass awns, foxtails, or small debris can become lodged deep in the ear canal. This causes sudden, intense scratching and head shaking, often with whining. Foreign bodies require prompt veterinary removal to prevent deeper damage.
Trauma or Growths
A scratch or bite wound on the ear flap can become infected and painful. Less commonly, polyps or tumors in the ear canal can cause irritation and lead to scratching. These are more typical in older dogs.
When to Visit the Veterinarian
Persistent scratching and noise that lasts more than a day or two warrants a veterinary exam. You should also seek immediate care if you notice:
- Swelling, redness, or bleeding from the ear
- A strong, unpleasant smell
- Thick discharge (yellow, brown, or bloody)
- Your dog seems lethargic, loses balance, or tilts its head constantly
- Repeated head shaking that does not resolve
The vet will use an otoscope to look deep into the ear canal. They may take a sample of discharge to identify bacteria, yeast, or mites under a microscope. This allows them to prescribe the most effective treatment.
Home Care and Prevention
You can take several steps to support your dog's ear health and reduce the likelihood of future problems.
Gentle Cleaning
Use a vet-recommended ear cleaner to gently wipe away visible debris from the outer ear. Never insert cotton swabs deep into the canal; this can push material further in and damage the eardrum. Clean only as directed by your veterinarian.
Drying After Water
Moisture creates an ideal environment for infections. After baths or swimming, gently dry your dog's ears with a soft cloth. For dogs prone to infections, a drying ear solution may be helpful.
Allergy Management
Work with your vet to identify and manage allergies. This may involve dietary changes, antihistamines, or medicated ear drops during allergy season.
Regular Checks
Inspect your dog's ears weekly, especially after outdoor activities. Look for redness, discharge, or foreign matter. Early detection makes treatment simpler and faster.
What to Expect at the Vet
The treatment plan depends on the diagnosis. For infections, your vet will likely prescribe medicated ear drops or ointments to be applied for one to two weeks. Oral antibiotics or antifungals may be added for severe cases.
Ear mites are treated with topical medications that kill the parasites, often repeated after two weeks to break the life cycle. All foreign objects are removed under sedation or anesthesia to prevent further injury.
Your vet may recommend a follow-up visit to ensure the infection has cleared. Stopping treatment early can lead to recurrence.
Long-Term Outlook
Most ear problems resolve well with appropriate treatment. However, dogs with chronic allergies or anatomical predispositions may experience repeated episodes. In such cases, your vet might suggest a maintenance cleaning schedule or long-term allergy therapy.
Paying attention to your dog's scratching and the noises they make is an important part of responsible pet care. Early intervention can spare your dog unnecessary pain and prevent complications. Always consult a veterinarian for a proper diagnosis and tailored treatment plan.
