21 May How to treat itchy ears in dogs
If your dog is constantly scratching, shaking their head or rubbing their ears on furniture, you are not alone. Ear irritation is one of the most common reasons dogs visit the vet, and while it may seem minor at first, ongoing discomfort can quickly develop into painful ear infections or chronic disease.
Many owners wonder what causes itchy ears in dogs, whether they can manage symptoms at home, or if veterinary care is necessary. The truth is that itchy ears are often a symptom rather than a diagnosis, and identifying the underlying cause is key to successful treatment and long-term health.
If your pet is showing signs of discomfort, you can contact Southern Cross Vet or book a consultation for Gold Standard veterinary care by calling 1300 DOC SAM (1300 362 726) or visiting https://southerncrossvet.com.au/contact/book-appointment/
Recognising the signs of ear discomfort
When a dog has itchy ear symptoms, behaviour changes are usually the first clue. Signs to watch for include persistent scratching, head shaking, redness, odour, discharge and sensitivity when touching the head or ears. Some dogs may tilt their head, lose balance or become reluctant to have their ears handled.
Dogs with chronic ear infections may show subtle signs because they have adapted to discomfort. Regular ear checks at home can help you detect changes early and seek care before complications develop.
What causes itchy ears in dogs?
Understanding what causes itchy ears in dogs helps guide treatment and prevents recurrence. In many cases, bacteria or yeast infections are secondary problems that develop after the ear’s natural defences are disrupted (AVA, 2022).
Common underlying causes include allergies, ear mites, moisture trapped in the ear canal, foreign bodies such as grass seeds, excessive wax, abnormal ear anatomy and immune-related skin conditions. Hormonal disorders and parasites can also contribute to inflammation.
Because multiple factors may be involved, professional assessment is often required to accurately find the root cause.
Allergies and chronic ear disease
Allergy driven inflammation is one of the leading causes of recurrent ear problems in dogs. When allergies affect the skin and ear canal, inflammation creates an environment where yeast and bacteria thrive.
This is particularly relevant for breeds with floppy ears or dense hair growth, including Cavaliers, Poodles and Cavapoos. A cavoodle ear infection often develops due to moisture retention and reduced airflow within the ear canal.
In suitable cases, allergy-focused treatments such as Cytopoint injections may help reduce itch by targeting immune pathways responsible for inflammation. By decreasing overall itch, dogs scratch less, trauma to the ears is reduced and long-term ear health improves. Your vet will determine whether this approach is appropriate based on clinical history and examination findings.
Ear mites and parasite-related irritation
Ear mites are microscopic parasites that live in the ear canal and are a frequent cause of irritation, particularly in young animals. Dogs with ear mites may show intense scratching, dark discharge and persistent head shaking.
Veterinary microscopic examination is usually required to confirm ear mites and guide treatment, as symptoms can resemble bacterial or yeast infection (Merck Veterinary Manual, 2023).
Why scratching can occur without fleas
Owners often ask why their dog scratches ears despite no visible fleas. The answer typically lies in allergies, yeast overgrowth, ear mites, contact dermatitis or foreign bodies. In some cases, chronic ear infection may exist without obvious external signs.
A thorough ear examination and cytology testing allow accurate diagnosis and targeted treatment.
Can itchy ears be treated at home?
Mild irritation may sometimes be soothed with supportive home care, such as gently cleaning the outer ear with a vet-approved solution and keeping ears dry after bathing. However, inserting cotton buds into the ear canal or using household remedies can worsen inflammation or damage delicate structures.
Because untreated ear disease can progress quickly, persistent symptoms should be evaluated by a veterinarian rather than relying solely on home remedies.
If your dog’s ears remain irritated beyond 24 to 48 hours, it is best to contact Southern Cross Vet for assessment.
How to treat itchy ears in dogs
Treatment varies depending on the underlying cause and may include prescription ear drops, anti-inflammatory medication, parasite therapy for ear mites, allergy management and structured cleaning protocols. Diagnostic testing such as ear cytology helps determine whether yeast, bacteria or mixed infections are present (WSAVA, 2020).
Each infection can differ from previous episodes, which is why tailored treatment is important rather than reusing leftover medication.
Breed predispositions and recurrent infections
Certain breeds are more prone to ear problems due to ear structure, hair growth or allergy predisposition. Cavaliers, Cavapoos and Spaniels may experience recurrent infections requiring ongoing monitoring and preventative care.
Routine ear checks, grooming and allergy management strategies can significantly reduce recurrence risk and improve comfort.
Advanced care for chronic ear disease
For dogs with persistent or complicated ear disease, Southern Cross Vet offers endoscopic ear flushing and examination. This advanced procedure allows detailed visualisation of the ear canal using specialised equipment and enables removal of debris, foreign material and obstructive discharge.
Performed under anaesthesia, endoscopic ear cleaning allows sampling, diagnosis and thorough flushing that may not be possible during routine examination. Many dogs recover quickly and benefit from improved treatment outcomes following the procedure.
If your dog has a history of chronic ear infections or difficult-to-manage symptoms, our team can discuss whether this advanced service is appropriate.

Preventing itchy ears in dogs
Preventative ear care is essential for long-term comfort and includes routine ear checks, parasite control, allergy management, grooming and keeping ears dry after swimming. Regular veterinary check-ups help detect early changes before infections develop.
Preventative strategies support overall pet health and reduce the likelihood of chronic disease.
When to seek veterinary care
You should seek veterinary assessment if your dog shows persistent scratching, discharge, swelling, odour, pain or balance changes. Early treatment reduces discomfort and prevents progression to middle or inner ear disease.
If your dog is uncomfortable, Southern Cross Vet is here to help. You can book a consultation for expert ear care and personalised treatment planning.
Supporting lifelong ear health
Ear irritation is uncomfortable but highly manageable when addressed early. By understanding causes, recognising symptoms and maintaining preventative care, you can help your dog enjoy healthy ears throughout life.
