With one little NexGard® (afoxolaner) chew comes the confidence that you’re giving your dog the #1 vet-recommended flea and tick control. Dogs love the beef-flavored NexGard chewables, and they're easy to give with or without food. Numerous studies have proven that NexGard is safe and effective, and NexGard is the #1 choice of vets. The ingredients in each NexGard chew were carefully designed to quickly kill fleas and ticks for a full month, while being safe and gentle enough to give to puppies as young as 8 weeks and dogs weighing as little as 4 pounds. NexGard kills fleas fast, before they have a chance to lay eggs. NexGard is a flea and tick control product that’s FDA-approved to prevent infections that cause Lyme disease in dogs as a result of killing black-legged ticks.
