DOSAGE & ADMINISTRATION

NexGard® makes monthly dosing a rewarding, shared experience between pet owner and dog. Dogs prefer the beef-flavored flea and tick chew.3
 
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, re-dose with another full dose. If a dose is missed, administer a NexGard® chew and resume a monthly dosing schedule.
 

Flea Treatment and Prevention: Treatment with NexGard® chews may begin at any time of the year. In areas where fleas are common year-round, monthly treatment with NexGard® chews should continue the entire year without interruption. To minimize the likelihood of flea reinfestation, it is important to treat all animals within a household with an approved flea control product.
 

Tick Treatment and Control: Treatment with NexGard® may begin at any time of the year.
