Nexgard Flea, Tick Monthly Chew for Dogs

NexGard chewable is a monthly oral treatment for fleas and ticks in dogs. It comes in a soft and tasty beef-flavored chew that protects dogs for one full month. Being the number one choice of vets, it destroys adult fleas before they can even lay eggs, thus preventing flea infestations. This effective and palatable formula kills American dog ticks, Black-legged ticks, Lone star ticks, and Brown dog ticks. NexGard prevents flea-borne and tick-borne diseases like flea allergy dermatitis and Lyme disease in dogs.

NexGard chewable is very easy and convenient to dose, as its delicious beefy flavor is loved by all dogs. You can give it to your dog with food, or just offer it as a treat! Fleas and ticks are more active in the summer, but if they find their way into your warm home during the winter, they will feast on your dog. Most veterinarians recommend treating your dog for fleas and ticks once a month regularly without missing any months.

How Nexgard Chewable Works?

NexGard contains afoxolaner as its main ingredient. Afoxolaner for dogs kills fleas and ticks by over-stimulating their nervous systems. When you treat your dog with a NexGard chew, its active ingredient, afoxolaner, enters the bloodstream of the dog and fights fleas and ticks whenever they bite your dog.
