Is NexGard PLUS worth it over plain NexGard?

Yes if you also want heartworm and roundworm coverage. Plain NexGard handles fleas and ticks only, so PLUS saves you a second monthly product. If your dog is already on a separate heartworm preventive, plain NexGard may cost less.

What weight of dog is this box for?

This purple box is for dogs 33.1–66 lbs. NexGard PLUS comes in other box colors for smaller and larger dogs, so match the weight band to your dog's current weight.

Can puppies take NexGard PLUS?

Yes, puppies can start at 8 weeks of age. Use the correct weight band, and check with your vet for puppies under the minimum weight for the smallest box.

Does it cover tapeworms?

No. NexGard PLUS covers roundworms, not tapeworms or whipworms. If tapeworms are a concern, ask your vet about a separate dewormer.

How often do I give it?

One chew once a month, ideally on the same date each month. Each box holds 6 chews, a six-month supply.

Our take on the NexGard PLUS

NexGard PLUS is a monthly beef-flavored chew that protects dogs against fleas, ticks, roundworms and heartworm disease. It combines afoxolaner, moxidectin and pyrantel in one tablet, so it replaces a separate heartworm preventive and dewormer. The 33.1–66 lb box of 6 chews is $115.19 at Chewy.com as of November 4, 2026, the lowest of the two stores listing it new. That works out to about $19 per month of protection.
