The active substance of NexGard is afoxolaner, a new ectoparasiticide belonging to the isoxazoline group, which is systemically active against ticks and fleas. The benefits of NexGard are its efficacy in the treatment of flea and tick infestations on dogs.

NexGard is a brand new, revolutionary flea and tick preventative from the makers of Frontline®, the #1 choice of veterinarians. It's the first flea and tick killer of its kind because it comes in a yummy, beef-flavored soft chew that protects your dog from a flea and tick infestation for a full 30 days.

NexGard is for use in dogs only. The most frequently reported adverse reactions include vomiting, dry/flaky skin, diarrhea, lethargy, and lack of appetite. The safe use of NexGard in pregnant, breeding or lactating dogs has not been evaluated. Use with caution in dogs with a history of seizures.
