What Are Ear Mites?
Ear Mites( Otodectes cynomus) are tiny, like sponges that live on the surface of the Ear canal in dogs. These mites are largely contagious and can spread quickly among household pets, particularly between dogs and cats. Though more common in cats, dogs are susceptible, especially when exposed to infected animals or surroundings. Ear mites feed on wax and oil in the ear canal, causing significant irritation and inflammation.
Left untreated, an ear mite infestation can lead to secondary bacterial or yeast infections and even cause ear damage.
How Dogs Get Ear Mites
Dogs generally get ear mites through close contact with infected pets. Shared bedding, grooming sessions, and out-of-door exposure increase the likelihood of transmission. Puppies, shelter animals, and dogs in multi-pet homes are particularly at risk.
Environmental impurity is less common but possible, as mites can survive for a limited time off a host.

Signs and Symptoms of Ear Mites Infestation
The symptoms of ear mites in dogs frequently mimic those of bacterial or yeast infections. Key signs include:
- Intense scratching of the ears and head
- Frequent head shaking or tilting
- Dark, waxy discharge resembling coffee grounds
- Redness and inflammation inside the ear
- Strong, unpleasant odor
- Hair loss or scabs around the ear
- Whining or discomfort when ears are touched
In advanced cases, dogs may suffer from balance issues or hearing loss due to prolonged irritation and inflammation.
How Are Ear Mites Diagnosed?
Veterinarians use several ways to confirm the presence of ear mites:
- Physical Examination: An otoscope enables the veterinarian to view the ear canal for debris and mites.
- Microscopic Evaluation: A swab of ear discharge is examined under a microscope to detect mites or eggs.
- Cytology: Helps differentiate ear mites from other conditions like yeast infections or bacterial otitis.
- Response to Treatment: In some cases, if mites are suspected but not confirmed, a vet may define mite-specific drug and examiner improvement.
Accurate diagnosis is crucial to help with mistreatment and prolonged discomfort.
Treatment Options for Ear Mites
Effective treatment involves eliminating the mites, treating any secondary infections, and soothing the inflammation.
Cleaning the Ears
Completely cleaning the ear helps remove wax and debris where mites thrive. A vet may use results like Epi-Otic ® or TrizULTRA ™ with ketoconazole for binary cleansing and antifungal support.
Topical and Oral Medications: Veterinarians may prescribe
- Isoxazoline-based products: Bravecto ®( fluralaner), NexGard ®( afoxolaner), and Simparica ®(Caroliner) have proven strongly effective with long-lasting results.
- Prescription drops: Tresaderm ®, containing thiabendazole and dexamethasone, treat mites and inflammation.
- Selamectin( Revolution ®): A monthly topical treatment that also prevents fleas and ticks.
Some products kill mites with a single cure, while others require 7 – 10 days of treatment.
Anti-inflammatory medicines
If inflammation is severe, corticosteroids, such as prednisone, may be administered to alleviate swelling and discomfort.
Secondary Infection Treatment
Secondary infection treatment accompanies mite infestations. If present antibiotic or antifungal ear drops will be necessary, If present.
Follow-up and Monitoring
Full eradication can take 3 – 4 weeks. Follow-up vet visits ensure
- Complete removal of mites and their eggs
- Healing of ear tissue
- Adjustment of medication if symptoms persist
It is important not to discontinue treatment prematurely, as remaining eggs can reinitiate infestation.
Preventing Ear Mites in Dogs
Preventative care reduces the risk of reinfestation and protects other pets in the household.
Key Prevention Tips:
- Regular ear cleaning: Especially for floppy-eared dogs like Cocker Spaniels and Basset Hounds
- Monthly preventative: Products like Bravecto ® or Revolution ® cover both mites and fleas.
- Avoid sharing bedding, toys, and grooming tools.
- Treat all pets simultaneously: Mites spread easily; treating just one pet can lead to reinfection.
- Routine vet checks: Particularly for pets with a history of ear problems
Home Remedies: Are They Safe?
Some pet owners try home remedies for mild symptoms, but these should be approached with caution.
Potential remedies include:
- Olive oil painting or mineral oil: May smother mites but lack residual protection.
- Green tea rinse: Offers mild antiseptic properties.
- ⚠️ Warning: Avoid hydrogen peroxide, vinegar, or essential oils unless prescribed. These can worsen irritation or damage ear tissues.
Home remedies should not replace veterinary treatment, especially if symptoms are severe or persist.
Complications of Untreated Ear Mites
Ignoring ear mites can lead to serious health issues:
- Chronic ear infections
- Ruptured eardrums
- Permanent hearing loss
- Balance problems
- Systemic infections( in rare cases)
Early detection and treatment are critical to preventing these long-term effects.
