What to do if a dog has lice? - briefly
Isolate the dog, then apply a veterinarian‑approved lice treatment—such as a medicated shampoo or topical dip—and thoroughly clean bedding, grooming tools, and the living area to prevent reinfestation. Follow the vet’s dosage schedule and re‑examine the pet to confirm eradication.
What to do if a dog has lice? - in detail
If a canine shows signs of a lice infestation, begin by confirming the diagnosis. Examine the coat in natural light, looking for tiny, crab‑like insects, nits attached to hair shafts, or excessive scratching. Use a fine‑toothed comb to collect specimens for veterinary verification if the infestation is unclear.
Once lice are confirmed, follow these steps:
- Isolate the animal – Keep the dog separate from other pets for at least 48 hours to prevent cross‑contamination.
- Administer a topical or oral ectoparasiticide – Choose a product specifically labeled for canine lice. Apply according to the manufacturer’s instructions, ensuring full coverage of the skin surface. Oral medications may require a single dose; topical treatments often need a repeat application after 7‑10 days.
- Treat the environment – Wash all bedding, blankets, and toys in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and cracks in flooring; discard the vacuum bag or clean the canister afterward. For severe cases, apply an approved insecticide spray to the home’s interior, focusing on areas where the dog rests.
- Perform a thorough grooming session – After the first medication, comb the coat with a fine lice comb to remove dead insects and nits. Repeat the combing daily for a week.
- Monitor for secondary infections – Observe the skin for redness, pustules, or foul odor. If any appear, seek veterinary treatment for bacterial or fungal complications.
- Schedule a follow‑up examination – Return to the clinic 2‑3 weeks after initial treatment to verify that the infestation is resolved and to discuss any necessary repeat dosing.
Prevention measures include regular grooming, routine use of a preventative ectoparasiticide, and maintaining a clean living area. Avoid contact with stray animals or environments known to harbor lice. Prompt identification and systematic treatment eliminate the parasites and reduce the risk of skin irritation or secondary disease.
