NexGard Chew for Dogs: A Comprehensive Guide
Introduction
NexGard Chew is a revolutionary monthly chewable medication that provides effective and convenient protection against fleas and ticks for dogs. Developed by Boehringer Ingelheim Animal Health, NexGard has quickly become a trusted choice among veterinarians and pet owners alike. This article delves into the comprehensive benefits, mechanism of action, and usage guidelines of NexGard Chew, ensuring optimal health and well-being for your canine companion.
Understanding NexGard Chew
Mechanism of Action
NexGard Chew contains afoxolaner, a novel active ingredient that targets the nervous systems of fleas and ticks. When ingested by the dog, afoxolaner is rapidly absorbed into the bloodstream and distributed throughout the body. It then binds to specific receptors in the parasite's nervous system, causing paralysis and death.
Efficacy
NexGard Chew has demonstrated exceptional efficacy against both fleas and ticks. Studies conducted by Boehringer Ingelheim have shown that it:
- Kills 98-100% of adult fleas within 24 hours
- Kills 100% of adult ticks (including the American dog tick, deer tick, and lone star tick) within 48 hours
- Prevents re-infestation for up to 30 days
Benefits of NexGard Chew
Comprehensive Protection
NexGard Chew provides comprehensive protection against a wide range of fleas and ticks, including those that transmit serious diseases such as Lyme disease, heartworm disease, and Rocky Mountain spotted fever. This broad-spectrum protection ensures that your dog is shielded from harmful parasites and their potential health implications.
Convenience and Ease of Use
Unlike topical treatments or sprays, NexGard Chew is an oral medication that is easy to administer. The beef-flavored chew is highly palatable and readily accepted by most dogs. Its monthly administration schedule ensures consistent protection without the need for frequent reapplication.

NexGard Chew has an excellent safety profile and is well-tolerated by the majority of dogs. Clinical trials conducted by Boehringer Ingelheim have shown that it is safe for use in dogs as young as 8 weeks of age, weighing at least 2 pounds.
