Nexgard (afoxolaner) is a beef-flavored chew that dogs love. Given once monthly, Nexgard starts killing fleas and ticks on your pet in just two hours. It kills existing flea infestations, adult fleas before they can lay eggs and four kinds of ticks found here in South Texas. Since Nexgard is given by mouth, it offers a nice alternative to those messy topicals allowing your dog to swim or be bathed immediately. Nexgard is a prescription product readily available at our office so please call us for more information on how you can get your pet started on this awesome flea and tick product.
