NexGard is a monthly beef-flavoured chewable flea and tick treatment for large dogs weighing 25.1–50kg. The active ingredient afoxolaner works systemically to kill fleas and ticks through the dog's bloodstream — no topical application, no residue on coat or furniture.

NexGard kills fleas within 8 hours and provides 35 days of flea protection, effectively breaking the flea life cycle. It covers paralysis ticks — critical for dogs in eastern and coastal Australia — as well as brown dog ticks, bush ticks, demodex, and sarcoptic mange mites. The braised beef-flavoured soy protein chew is highly palatable, and most large breed dogs accept it readily at feeding time without concealment.

For large breed owners in tick-prone regions, NexGard's monthly chew format and reliable paralysis tick coverage have made it one of the most widely used flea and tick products in Australia. No mess, no spot-on residue, and most dogs consider it a treat rather than a treatment.
