NexGard Flea & Tick Chewables is a completely new, breakthrough flea and tick preventative from the creators of Frontline, the vets' preferred option. It is the first flea and tick killer of its kind because it comes in a tasty, beefflavored soft chew that shields your dog from a flea and tick infestation for a full 30 days. This means you can stop worrying about messy topicals or bath time accidents where you wash your dog's preventative off. Additionally, it can be administered continuously along with your dog's heartworm preventative. By eliminating adult fleas before they can develop eggs, NexGard tablets protect your pet from fleas and lessen the likelihood of a flea infestation. Plus, it kills the Lone Star tick, Blacklegged tick, American dog tick, and Brown dog tick, which decreases the risk of your pet developing a deadly tickborne disease such as Lyme disease. It is safe and suitable for dogs and puppies at least 8 weeks of age and weighing 4 lbs.
