NexGard is a monthly chewable flea and tick treatment for large dogs weighing 25.1 to 50 kilograms. The soft, beef-flavoured chew is designed to be given once a month, covering fleas, the paralysis tick, mites, lice, and flea tapeworm. It's suitable from puppy age and is taken willingly by most dogs as a flavoured treat.

Each monthly chew works systemically — no topical residue, and no need to keep dogs away from water after dosing. The formula kills fleas rapidly after ingestion and provides 35 days of coverage, helping break the flea life cycle before eggs establish in the environment. Paralysis tick protection is particularly relevant for dogs in eastern coastal regions of Australia. NexGard is veterinary-formulated and one of Australia's most widely prescribed monthly flea and tick treatments.

Monthly dosing keeps the regimen straightforward, and the chew format removes the need for pill-hiding or topical spot-on application. Most dogs take it readily at treat time, which makes consistent monthly compliance considerably easier than it sounds. For dogs in paralysis tick regions, the 35-day coverage window aligns with the recommended monthly treatment schedule.
