NexGard chews can be administered with or without food. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes to ensure that part of the dose is not lost or refused. If it is suspected that any of the dose has been lost or if vomiting occurs within 2 hours of administration, redose with another full dose. If a dose is missed, administer a NexGard chew and resume a monthly dosing schedule.
