NexGard is a monthly beef-flavoured chewable for dogs that treats and prevents flea and tick infestations, including the paralysis tick — a serious risk along Australia's east coast. This 6-pack provides six months of protection and is sized by weight bracket, so it's important to match the pack to your dog's current weight.

The active ingredient afoxolaner kills fleas within hours and provides 35 days of flea control plus one month of paralysis tick and brown dog tick protection. It also treats demodectic and sarcoptic mange and covers biting lice. Because it's an oral chew rather than a spot-on, bathing, swimming and coat contact don't affect how well it works.

Owners typically choose NexGard because dogs eat it willingly as a treat, which removes the wrestling match that comes with topicals. The single-chew monthly dose is easy to remember, and the paralysis tick coverage is the main draw for anyone in tick country.
