What to do when a dog has lice? - in detail
If a canine shows signs of lice—itching, visible nits attached to hair shafts, or flaky skin—prompt action prevents secondary infections and spread to other pets.
First, confirm the infestation. Examine the coat in bright light, parting the fur to expose the scalp. Lice appear as tiny, wingless insects, often white or tan, while their eggs (nits) cling firmly to hair. A fine-toothed comb can help collect specimens for veterinary verification.
Next, isolate the animal. Keep the dog in a separate room for at least 24 hours, limiting contact with other pets. Wash all bedding, blankets, and toys in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and floors thoroughly; discard the vacuum bag or empty the canister into a sealed bag.
Select an appropriate treatment. Options include:
- Topical insecticidal shampoos or dips – apply according to label instructions, ensuring full coverage of the coat and skin. Rinse after the recommended contact time.
- Spot‑on products – dispense the calibrated dose directly onto the skin at the base of the neck; avoid contact with eyes and mucous membranes.
- Oral systemic medication – administer prescribed tablets or chewables that target lice internally; follow the veterinarian’s dosage schedule.
Do not combine multiple chemical treatments without veterinary guidance, as interactions may cause toxicity.
After treatment, repeat the combing process every 2–3 days for two weeks to remove any surviving nits. Maintain a clean environment by laundering the dog’s collar, leash, and grooming tools after each use.
Schedule a follow‑up examination within one week. The veterinarian will assess treatment efficacy, address any skin irritation, and recommend preventive measures such as regular grooming, routine flea and tick preventatives, and environmental sanitation.
If symptoms persist—continuous itching, hair loss, or skin lesions—seek immediate veterinary attention to rule out secondary infections or resistant parasites.
