Dog has advanced ear tick: how to treat? - briefly
When a canine presents with a severe ear‑mite infestation, immediate veterinary assessment is essential. Treatment includes meticulous ear cleaning, application of a topical acaricide such as selamectin or moxidectin, and, if indicated, an oral ivermectin course with follow‑up prevention measures.
Dog has advanced ear tick: how to treat? - in detail
A severe ear mite infestation in a dog requires prompt, systematic intervention to eliminate parasites, relieve inflammation, and prevent recurrence.
First, confirm the diagnosis. Look for dark, coffee‑ground debris in the ear canal, intense itching, and a foul odor. Microscopic examination of the material will reveal the characteristic oval mites.
Immediate measures:
- Cleaning: Warm the ear with a veterinarian‑approved ear cleanser. Gently flush the canal using a syringe, allowing the solution to dissolve debris. Repeat until the ear appears clear of wax and crusts.
- Topical acaricide: Apply a single‑dose medication containing active ingredients such as selamectin, moxidectin, or milbemycin oxime. Follow the label for dosage based on body weight. Repeat the application after 7–10 days to eradicate any newly hatched mites.
- Anti‑inflammatory relief: Use an otic preparation with hydrocortisone or a non‑steroidal anti‑inflammatory to reduce swelling and pruritus. Limit use to the prescribed duration to avoid tissue thinning.
Supportive care:
- Systemic therapy: Oral ivermectin or a milbemycin‑based product may be indicated for dogs with extensive infestation or secondary bacterial infection. Dosage must be calculated by a veterinarian.
- Antibiotics/antifungals: If bacterial overgrowth or yeast is present, prescribe appropriate topical or oral agents based on culture results.
- Environmental control: Wash bedding, toys, and grooming tools in hot water. Vacuum the home thoroughly and treat any other pets simultaneously to prevent cross‑infection.
Monitoring and follow‑up:
- Re‑examine the ears 2 weeks after the initial treatment. Ensure that debris has cleared and that the ear canal skin appears pink and intact.
- Conduct a second microscopic check to verify the absence of live mites.
- Schedule a third evaluation at 4–6 weeks to confirm long‑term resolution and to discuss preventive measures, such as regular prophylactic ear drops or monthly heartworm preventatives that also cover ear mites.
Preventive strategy:
- Apply a monthly topical or oral broad‑spectrum parasite preventer.
- Perform routine ear inspections during grooming sessions, especially in humid climates or when dogs spend time outdoors.
- Keep the ear canal dry; after swimming or bathing, gently dry the outer ear with a soft cloth.
By combining thorough cleaning, targeted acaricidal therapy, anti‑inflammatory support, and diligent follow‑up, an advanced ear mite problem can be resolved efficiently, restoring the dog’s comfort and preventing future infestations.
