How can you get rid of fleas and lice on dogs? - briefly
Apply a veterinarian‑approved topical or oral flea‑and‑lice medication, then bathe the dog with a suitable insecticidal shampoo and comb out any remaining pests. Clean the pet’s bedding, vacuum the environment thoroughly, and repeat the treatment according to the product’s schedule to prevent reinfestation.
How can you get rid of fleas and lice on dogs? - in detail
Eliminating both fleas and lice from a dog requires a coordinated approach that targets the animal, its living environment, and any secondary infestations.
Begin with a thorough inspection. Use a fine‑toothed comb to separate adult insects and eggs from the coat, focusing on the neck, base of the tail, and under the belly. Collect the found specimens for identification; confirming the presence of both species guides treatment selection.
Administer an appropriate topical or oral parasite product. Products containing fipronil, imidacloprid, or selamectin are effective against fleas, while formulations with pyrethrins or lufenuron address lice. Follow the manufacturer’s dosage instructions based on the dog’s weight, and repeat the application according to the recommended interval (usually 30 days) to break the life cycle.
Give the dog a medicated bath. Use a shampoo formulated for both fleas and lice, allowing the lather to remain on the skin for the time specified on the label. Rinse thoroughly, then dry the coat with a clean towel or low‑heat dryer to prevent re‑infestation.
Treat the surrounding environment simultaneously. Wash all bedding, blankets, and toys in hot water (≥ 60 °C) and dry on a high heat setting. Vacuum carpets, upholstery, and cracks in flooring; discard the vacuum bag or clean the canister afterward. Apply an environmental spray or fogger containing an insect growth regulator (IGR) to indoor areas where the dog spends time, ensuring ventilation during and after application.
Implement preventative measures. Use a monthly flea‑preventive collar or oral tablet to maintain protection. Groom the dog regularly with a flea‑comb to detect any resurgence early. Keep the yard trimmed, remove standing debris, and consider treating outdoor areas with a pet‑safe insecticide if fleas are present in the environment.
If the infestation persists after two treatment cycles, consult a veterinarian. Prescription medications such as spinosad or a combination of ivermectin and milbemycin may be required, and a professional assessment can rule out underlying skin conditions that complicate control.
