How is ear mite treated in dogs? - briefly
Topical acaricides such as «selamectin», «imidacloprid‑moxidectin» or lime‑sulfur dips are applied to the ear canal according to veterinary dosage guidelines. A repeat application after 7–10 days and thorough ear cleaning complete the treatment.
How is ear mite treated in dogs? - in detail
Ear mite infection in canine patients is caused by the parasite Otodectes cynotis. Infestation produces intense itching, dark brown discharge, and inflammation of the ear canal. Early identification prevents secondary bacterial infection and chronic otitis.
Diagnosis relies on visual inspection with an otoscope and microscopic examination of ear swabs. Representative findings include live mites, eggs, and fecal pellets (“ear dust”). Cytology confirms the presence of the organism and excludes bacterial or fungal overgrowth.
Therapeutic measures fall into three categories: topical acaricides, systemic agents, and ear cleaning.
- Topical products • Amitraz‑based solutions applied to the ear canal once daily for three consecutive days. • Selamectin spot‑on formulation administered to the skin, reaching the ear through systemic absorption. • Moxidectin‑containing ear drops given at 7‑day intervals for two applications.
- Systemic medications • Ivermectin administered orally at 0.2 mg/kg, repeated after 7 days. • Milbemycin oxime given at the standard preventive dose, repeated after 14 days.
- Cleaning protocol • Warm, isotonic saline or a veterinary‑approved ear cleanser introduced into the canal. • Gentle flushing with a syringe, followed by thorough drying with gauze. • Cleaning performed before each topical application to remove debris and improve drug contact.
Post‑treatment management includes a second round of medication as indicated, typically 7–14 days after the initial dose, to eradicate newly hatched mites. Environmental decontamination—washing bedding, toys, and grooming tools at high temperature—reduces reinfestation risk. Follow‑up otoscopic examination after two weeks confirms resolution; persistent signs warrant repeat cytology and possible adjustment of therapy.
