Nexgard is an oral flea and tick treatment commonly used for dogs in the United States. It contains a compound called afoxolaner, which targets the nervous system of parasites, effectively killing fleas and ticks after they bite. Administered as a chewable tablet, Nexgard is typically given monthly and is known for its ease of use compared to topical treatments. It is often recommended by veterinarians as part of a broader parasite control plan. While effective, Nexgard should be used according to veterinary guidance, as some dogs may experience side effects. Its use contributes to the overall health and comfort of pets.
