Veterinary Guide to Ear Mites in Dogs 2025 🐶🩺

By Dr. Duncan Houston BVSc

🔍 Introduction

Ear mites—tiny parasites called Otodectes cynotis—thrive in the ear canals of dogs and cats, causing intense itching, irritation, and dark debris buildup. While more common in puppies and outdoor pups, ear mite infestations also occur in adult dogs that sleep near other pets. In this 2025 veterinary guide, I share professional insights on causes, symptoms, diagnostics, treatment, and prevention. 🕷️👂

👂 What Are Ear Mites?

• Microscopic arachnids live in ear canal wax and oils.
• Causes severe irritation, head shaking, scratching, and possible hearing issues if untreated.
• Highly contagious among household pets—spread via sharing bedding, toys, or direct contact.

🚨 Symptoms to Watch For

• Frequent head shaking and scratching at the ears.
• Red, inflamed ear canals with a foul odor.
• Dark brown/black “coffee-ground” discharge.
• Hair loss around ears/eyes, and pawing at ears.
• Occasionally, head tilt or reduced appetite, and lethargy in severe cases.

🔬 How Vets Diagnose Ear Mites

• Physical exam using an otoscope to assess inflammation/debris.
• Cytology: swab, mineral oil slide, microscopic detection of mites/eggs.
• Concurrent testing for yeast or bacteria if infection is suspected.

🛠 Treatment Plan

1. Ear Cleaning

• Use a gentle ear cleanser (e.g., Epi-Otic® or TrizULTRA™+ Keto Flush) daily to remove debris and allow meds to penetrate the canal.

2. Medications

• Topical or systemic parasiticides such as selamectin, ivermectin, or isoxazolines (moxidectin) are used off-label but are highly effective.
• Once-monthly flea/tick/heartworm preventatives—e.g., Bravecto®, Advantage Multi™—often eliminate mites.
• If secondary infections develop, add topical antibiotics or antifungals (e.g., Animax®).
• Steroids (topical/oral) may be prescribed for discomfort and swelling relief.

3. Follow-Up & Household Treatment

• Retest ear cytology in ~30 days to confirm mite elimination—repeat treatment if needed.
• Treat all pets in the household simultaneously to prevent reinfestation.
• Thoroughly clean pet sleeping areas, bedding, toys, and grooming tools.

🌿 Natural Home Support (Vet-Guided)

For situations awaiting vet care, some owners use:

• Green tea rinse to flush out debris once daily for up to 1 month.
• Olive, corn, or mineral oil (with garlic infusion removed) to help suffocate mites.

These are **complementary therapies only** and must be used with veterinary approval, as they don’t target eggs and may require a full treatment course.

📈 Recovery & Prognosis

• Most dogs begin feeling better within 48 hours; full resolution may take up to 30 days to cover the mite life cycle.
• Untreated mites cause chronic inflammation, secondary infections, and ear canal damage.
• Proper treatment and follow-up generally lead to full recovery and normal hearing.

🛡️ Prevention Strategies

• Year-round parasite prevention with flea/tick/heartworm products, including mite coverage.
• Routine ear cleaning (weekly to monthly, depending on breed).
• Keep ears dry post‑swimming or bathing, especially in floppy-eared dogs.
• Prompt vet visits for any ear scratching or discharge to identify mites early.
