What should I do if a puppy has lice? - in detail
If a young dog is found with lice, act promptly to stop the infestation and prevent spread.
First, confirm the diagnosis. Examine the coat for tiny, gray‑white insects moving slowly, especially around the neck, ears, and tail base. Look for pale, crusty skin and excessive scratching. If uncertainty remains, schedule a veterinary examination for accurate identification.
Second, isolate the puppy. Keep it separate from other pets for at least 48 hours to avoid cross‑contamination. Limit its access to shared bedding, toys, and grooming tools.
Third, initiate treatment. Options include:
- Topical insecticidal shampoos: Apply a lice‑specific shampoo according to the label, ensuring thorough coverage of the entire body. Rinse after the recommended dwell time.
- Spot‑on products: Use a veterinarian‑approved spot‑on solution, placing the dose on the back of the neck where the puppy cannot lick it.
- Oral medication: In severe cases, a vet may prescribe an oral antiparasitic that targets lice.
Follow the product’s dosage schedule precisely; many treatments require a repeat application 7–10 days after the first dose to eliminate newly hatched lice.
Fourth, decontaminate the environment. Wash all bedding, blankets, and toys in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and floors thoroughly, then discard the vacuum bag or clean the canister. Treat the household with an approved environmental spray if recommended by the veterinarian.
Fifth, monitor the puppy’s condition. Check the coat daily for remaining insects or irritation. If itching persists, consult the vet for possible secondary skin infection or allergic reaction, which may require additional medication such as antihistamines or antibiotics.
Finally, implement preventive measures. Maintain a regular grooming schedule, keep the living area clean, and use a preventive ectoparasite product as advised by the veterinarian to reduce the risk of future infestations.
