How do I administer NexGard Spectra to my dog?

The beef flavored chew can be easily offered as a treat or added intact to food. Monitor your dog to ensure all pieces of the tablet have been swallowed. If part of the dose is rejected or lost, treat again with another full dose. NexGard Spectra does not need to be administered with food.

Can I administer more than one dose per month?

NexGard Spectra provides month-long protection against parasites, so it is not necessary or recommended to administer the chews more frequently. For continuous coverage, make sure you dose your dog on the same day each month.

Why do I see more fleas on my dog after dosing?

NexGard Spectra works by overstimulating a flea’s nervous system. During this process they become more active and rise to the top of your dog’s coat, where they can be seen more easily.

Is NexGard Spectra effective for heavy flea infestations?

NexGard Spectra helps to control flea infestations by killing fleas on your dog before they can lay eggs, breaking the breeding cycle. If your home is heavily infested, you may see pre-existing eggs and larvae hatch and develop in the weeks following the first dose, but these will be killed with subsequent doses.

Can I divide NexGard Spectra tabs to give to more than one dog?
