How should a dog's ear be medicated when it has ear mites? - briefly
Apply a veterinary‑approved acaricide (e.g., selamectin, moxidectin, or a pyrethrin‑based ear drop) directly into the affected canal after cleaning out debris with a gentle cleanser. Follow the product’s dosing schedule and repeat treatment as directed to eradicate the infestation.
How should a dog's ear be medicated when it has ear mites? - in detail
When ear mites infest a canine ear canal, treatment begins with a thorough examination to confirm the presence of live parasites, debris, and any secondary bacterial or fungal infection. The veterinarian may collect a sample of ear wax and examine it under a microscope.
The next step is cleaning. A veterinarian‑approved ear cleanser, typically containing a mild surfactant and antiseptic, should be applied according to the product instructions. Gently massage the base of the ear for 30–60 seconds, then allow the dog to shake. Use gauze or cotton to wipe away softened debris; avoid inserting anything deep into the canal.
After the ear is dry, apply a topical acaricide. Common options include:
- Selamectin – applied once monthly; covers mites, fleas, and some parasites.
- Moxidectin – used as a liquid drop, usually every two weeks for three applications.
- Milbemycin oxime – administered orally but effective for ear mites; dosage based on weight.
- Ivermectin – topical formulation; applied once, repeat after 7 days if needed.
If inflammation is severe, a corticosteroid or non‑steroidal anti‑inflammatory agent may be added to reduce swelling and itching. For secondary infections, a broad‑spectrum antibiotic or antifungal ear drop should be used concurrently, following culture results when available.
Dosage guidelines:
- Calculate the dog’s weight in kilograms.
- Follow the manufacturer’s concentration chart; administer the exact volume to the ear canal.
- Ensure the medication reaches the deep canal by gently pulling the ear flap back and instilling the drop.
Frequency and duration:
- Initial treatment: apply the acaricide daily for 5–7 days.
- Continue weekly applications for an additional 2–3 weeks to eradicate any residual eggs.
- Anti‑inflammatory or antimicrobial drops: usually twice daily for 7–10 days, then taper as directed.
Monitor the dog’s response. Persistent debris, foul odor, or continued scratching after the full course indicates possible resistance or secondary infection, requiring a veterinary reassessment. Regular ear checks and routine cleaning prevent reinfestation.
