How to kill fleas on a dog? - in detail
Fleas infest a canine rapidly; immediate eradication prevents skin irritation, anemia, and secondary infections.
Identify the severity by counting fleas on the coat and examining the environment for eggs, larvae, and pupae.
Apply a multi‑modal control plan:
- Topical spot‑on products containing fipronil, imidacloprid, or selamectin; apply directly to the skin at the base of the neck, following label dosage.
- Oral systemic medications such as afoxolaner, fluralaner, or nitenpyram; administer according to weight specifications, ensuring full absorption within 24 hours.
- Medicated shampoos with pyrethrins or chlorhexidine; lather thoroughly, maintain contact for the recommended time, then rinse.
- Environmental sprays or foggers with insect growth regulators (IGRs) like methoprene or pyriproxyfen; treat carpets, bedding, and resting areas to interrupt the life cycle.
- Regular vacuuming of floors and upholstery; dispose of vacuum bags immediately to remove eggs and larvae.
Concurrent environmental decontamination is essential. Wash all bedding, toys, and grooming tools in hot water (≥ 60 °C). Apply diatomaceous earth to cracks and crevices, allowing it to remain dry for several days before cleaning.
Maintain preventive protection by scheduling monthly topical or oral preventatives, keeping the dog’s coat brushed to detect early infestations, and limiting exposure to flea‑prone areas such as tall grass or untreated wildlife habitats.
Consistent application of these measures eliminates existing fleas and suppresses future outbreaks.
