Nexgard for Dogs

Nexgard Flea & Tick Chewables

What is Nexgard?

Nexgard is a highly palatable beef-flavored, easy-to-use chewable flea and tick treatment for dogs and puppies 8 weeks of age or older, weighing 4 lbs or greater. It kills adult fleas and is indicated for the treatment and prevention of flea infestations. The treatment also treats and controls tick infestations of Black-legged tick, American dog tick, Lone star tick, Brown dog tick and Longhorned tick for a complete month.

Lyme Disease Prevention

Nexgard is indicated for the prevention of Lyme disease infections (Borrelia burgdorferi) as a direct result of killing the Black-legged ticks that transmit the bacteria.

How does it work?

Nexgard contains afoxolaner as its active ingredient. After administration, this active component is quickly absorbed into the dog's bloodstream. Afoxolaner works by interrupting the neurotransmission of the parasite. As soon as fleas and ticks bite the Nexgard-treated dog, they ingest afoxolaner which causes hyperexcitation in the parasites' nervous system and kills them.

Nexgard starts killing fleas within four hours of administration and kills them before they can lay eggs. It kills more than 99% of fleas within eight hours and is known to achieve 100% effectiveness against adult fleas 24 hours post-infestation.
