NexGard Spectra is a monthly beef-flavoured chew that delivers broad-spectrum parasite protection for dogs in a single dose. The 7.6–15kg size suits medium-breed dogs, with an additional pack option for large dogs in the 30.1–60kg weight range. Each chew is designed to be given like a treat, avoiding the mess of spot-ons or the fuss of separate tablets.

A single monthly chew covers fleas, three tick species (including the paralysis tick), heartworm, and intestinal worms — roundworms, hookworms and whipworms. The active ingredients begin killing fleas within hours, and the beef flavouring is formulated to be palatable enough that most dogs accept it without hiding it in food. One product replaces the stack of separate flea, tick, worm and heartworm treatments many households juggle.

Owners tend to choose NexGard Spectra when they want the simplest possible parasite routine — one chew, one date in the calendar, all the main parasites covered. It's a practical option for households with tick exposure or dogs that resist tablets and topical treatments.
