How to treat a dog for lice? - briefly
Apply a veterinarian‑approved lice shampoo or topical medication, following the label directions and ensuring full coverage of the coat and skin, then repeat the treatment after 7–10 days to interrupt the parasite’s life cycle. Clean bedding, grooming tools, and living areas with an appropriate insecticide or hot wash to prevent reinfestation.
How to treat a dog for lice? - in detail
Treating a canine lice infestation requires a systematic approach: confirm the diagnosis, select an appropriate ectoparasiticide, apply it correctly, and implement environmental control.
First, verify the presence of lice by examining the dog’s coat and skin. Look for small, crab‑like insects moving slowly, egg cocoons attached to hair shafts, and signs of irritation such as scratching, redness, or hair loss. A veterinary microscope can help differentiate lice from fleas or mites.
Second, choose a product specifically labeled for canine lice. Options include:
- Topical spot‑on treatments (e.g., selamectin, imidacloprid + moxidectin) applied along the back line.
- Oral medications (e.g., afoxolaner, fluralaner) that provide systemic action and also control other parasites.
- Shampoos containing pyrethrins, pyrethroids, or neem oil, used for immediate kill of adult lice.
Third, administer the chosen medication according to the label dosage. For spot‑on products, part the fur and apply the entire dose directly to the skin; avoid contact with eyes or mucous membranes. For oral tablets, give the full dose with food to enhance absorption. Shampoos must be lathered thoroughly, left on the coat for the recommended contact time (usually 5–10 minutes), then rinsed completely.
Fourth, repeat the treatment as directed, typically after 7–10 days, to eliminate newly hatched lice that survived the initial application. Most products require a second dose to break the life cycle.
Fifth, address the environment. Wash bedding, blankets, and any fabric the dog contacts in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and floor surfaces, then discard vacuum bags or clean the canister. For severe infestations, treat the home with a residual insecticide spray labeled for lice control, following safety precautions for humans and pets.
Sixth, monitor the dog for adverse reactions such as vomiting, lethargy, or skin irritation. If any signs appear, contact a veterinarian promptly. Maintain regular grooming and periodic health checks to detect re‑infestation early.
By following these steps—accurate diagnosis, targeted medication, proper application, repeat dosing, thorough environmental sanitation, and vigilant observation—a dog can be cleared of lice efficiently and safely.
