NexGard Flea & Tick Treatment for Dogs and Puppies

NexGard for dogs and puppies kills adult fleas and is indicated for the treatment and prevention of flea infestations (Ctenocephalides felis) and the control of tick infestations, including Ixodes scapularis (black-legged tick), helps prevent infections that cause Lyme disease, Dermacentor variabilis (American dog tick), Amblyomma americanum (lone star tick), Rhipicephalus sanguineus (brown dog tick), and Haemaphysalis longicornis (longhorned tick), and preventing fleas from laying eggs and multiplying. Use NexGard flea and tick chews for dogs older than 8 weeks and weighing 4 lb. or more.

How it Works

NexGard (afoxolaner) contains afoxolaner which is absorbed into the bloodstream after ingestion. When fleas and ticks ingest blood containing afoxolaner, it causes hyperexcitation and death in these parasites.
