NexGard Spectra is a monthly beef-flavoured chewable for large dogs (15.1–30kg) that covers fleas, ticks, mites, heartworm, and common intestinal worms in a single dose. One of the most comprehensive all-in-one oral parasite treatments available in Australia, it comes in 3-pack and 6-pack configurations for ongoing monthly protection.

The dual active ingredients — afoxolaner and milbemycin oxime — work together to address both external parasites (fleas, paralysis ticks, brown dog ticks, mites) and internal ones (heartworm, roundworm, hookworm, whipworm). Monthly dosing keeps the schedule straightforward. The soft, beef-flavoured chew is palatable enough that most dogs take it willingly, and flea kill begins within hours of the first dose.

Owners choose NexGard Spectra primarily for the coverage it delivers in one monthly chew — no separate spot-on, no worm tablet, no tick collar. For dogs in tick-prone areas, or households where missing a treatment could mean exposure to multiple parasites simultaneously, the all-in-one format is the practical choice.
