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. With an irresistible beef flavor, it’s the #1 choice for dogs, too. And because you should feel just as good about what your dog eats as he does eating it, 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. Plus, NexGard is the only flea and tick control that’s FDA-approved to prevent infections that cause Lyme disease in dogs. NexGard kills infected black-legged ticks before Lyme infection can be transmitted.
