NexGard is a monthly chewable flea and tick treatment for medium dogs weighing 10.1–25 kg. The soft, beef-flavoured chew protects against fleas, paralysis tick, brown dog tick, mites, lice, and flea tapeworm — covering the full range of common external parasites in a single monthly dose.

NexGard kills fleas rapidly and prevents reinfestation for 35 days, effectively breaking the flea lifecycle before numbers can establish. It also covers paralysis tick — the species responsible for the majority of tick paralysis cases in Australian dogs — along with brown dog tick, mites, lice, and flea tapeworm. Monthly dosing maintains continuous protection without gaps, and the beef flavour is accepted by most dogs without needing to be concealed in food.

The beef flavour means most dogs take NexGard without any fuss, which removes the compliance challenge that comes with other treatment formats. Monthly dosing is easy to schedule, and the paralysis tick coverage makes it particularly relevant for dogs in coastal and bushland regions of Australia.
