How to treat hair mites in dogs? - briefly
Use a veterinary‑prescribed acaricide such as selamectin, moxidectin, or a lime sulfur dip, applying it according to the label and repeating the treatment as directed. Follow with thorough grooming, environmental cleaning, and a vet‑approved preventive regimen to stop reinfestation.
How to treat hair mites in dogs? - in detail
Hair mite infestations in dogs require a systematic approach that combines accurate diagnosis, targeted medication, environmental sanitation, and preventive measures.
The first step is confirmation of the parasite. Veterinarians collect skin scrapings from affected areas and examine them under a microscope to identify the characteristic mites. A thorough physical exam helps assess the extent of skin lesions and rule out secondary bacterial or fungal infections.
Once the presence of mites is established, treatment proceeds with pharmacologic agents. Commonly prescribed options include:
- Topical acaricides such as amitraz‑impregnated collars or spot‑on formulations (e.g., selamectin, moxidectin). Apply according to the label schedule, typically every 30 days, to maintain therapeutic levels on the skin.
- Oral systemic drugs, especially ivermectin or milbemycin oxime, administered at the dosage recommended for the dog’s weight. These medications circulate to eliminate mites throughout the body and are effective for severe or generalized infestations.
- Medicated shampoos containing pyrethrins or chlorhexidine, used for bathing the animal once or twice weekly during the first two weeks of therapy. Allow the lather to remain on the coat for the recommended contact time before rinsing.
Environmental control is essential because hair mites survive off the host for a limited period. Implement the following steps:
- Wash all bedding, blankets, and clothing in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets, upholstery, and floor surfaces thoroughly; discard vacuum bags or clean canisters immediately.
- Apply an acaricide spray to the household environment if advised by the veterinarian, focusing on areas where the dog rests.
- Limit the dog’s access to untreated outdoor spaces until the infestation clears.
Follow‑up examinations should occur two weeks after initiating therapy to verify mite eradication. Repeat skin scrapings may be performed to confirm negative results. If lesions persist, adjust the treatment regimen—consider higher‑dose systemic medication or a combination of topical and oral agents.
Prevention relies on regular use of long‑acting spot‑on products or acaricide collars, routine grooming, and prompt attention to any signs of itching, hair loss, or scaly patches. Maintaining a clean living environment and avoiding contact with infested animals further reduces the risk of recurrence.
