With one little NexGard® (afoxolaner) chew comes the confidence that you’re giving your dog the #1 vet-recommended flea and tick control1. Numerous studies have proven that NexGard is both effective and safe for flea and tick protection. NexGard® (afoxolaner) flea and tick control chewable is FDA-approved to prevent infections that cause Lyme disease in dogs as a result of killing black-legged ticks. And each bite-sized monthly flea and tick treatment dose is gentle enough to give to puppies and dogs as young as 8 weeks, weighing as little as 4 pounds.
 
NexGard is also the #1 dog-preferred flea and tick protection over other brands2. Dogs love its irresistible beef flavor.3 And because you should feel just as good about the medicine your dog receives as he does taking it, the ingredients in each NexGard flea and tick Protection chew have been carefully designed to quickly kill fleas and ticks for a full month, killing fleas before they have a chance to lay eggs and black-legged ticks before they transmit Lyme infections. NexGard is flea and tick control for dogs that is easy to give, effective, and enjoyable, month after month.
