NexGard® PLUS
(afoxolaner, moxidectin, and pyrantel chewable tablets)
All dogs are at risk of coming into contact with common parasites such as fleas, ticks, heartworms, and intestinal worms. Year-round use of broad-spectrum preventative medication can help guard against uncomfortable symptoms and dangerous diseases that can harm your pet.
A combination product such as NexGard PLUS provides internal and external parasite control in a tasty beef-flavored soft chew to make dosing easier for dogs and pet parents alike. Ask your vet about “one-and-done” monthly protection to see if it’s the right fit for your canine companion!¹

NexGard® COMBO
(esafoxolaner, eprinomectin, and praziquantel topical solution)
Regardless of if they’re indoor or outdoor pets, cats are always at risk of parasites. Other animals in the home can bring critters indoors, rodents cats catch can transmit hookworms or roundworms, and ticks can even hitch a ride on your clothing after a day outside. That’s why it’s important to ensure your cat receives consistent parasite control all year long.
Formulated specially for cats, NexGard COMBO is the first and only monthly feline parasiticide that kills fleas and ticks, prevents heartworm disease, and treats and controls hookworms, roundworms, and tapeworms. Ask your vet about “one-and-done” topical protection to see if it’s the right fit.³

NexGard®

Fleas and ticks can be found in any season, all across the country – and no matter where you live, routine parasite control products are essential to protect your pet from discomfort and risky diseases such as Lyme.
NexGard was the first flea and tick product of its kind to market, and over 300 million monthly doses have been prescribed to date. Available in a delicious beef soft chew, it starts killing fleas within hours and continues to target both fleas and ticks all month long. Ask your vet about the #1 dog-preferred flea and tick chew to see if it’s right for your pet!⁵

Heartgard® Plus
(ivermectin/pyrantel)
Heartworm disease has been diagnosed in every state across the country, and just a single bite from an infected mosquito can spread this potentially deadly illness to your pet.

With more than 30 years of proven protection, Heartgard Plus is the #1 dog-preferred oral heartworm chew. Its real-beef flavor makes dosing easier and more enjoyable, and it prevents heartworm disease while also treating and controlling three species of hookworms and two species of roundworms – every month, all year long.⁷
