NexGard Spectra for dogs 15.1–30kg (Purple) is a monthly beef-flavoured chew delivering all-in-one parasite protection. The 3-pack covers three months of doses for large-breed dogs, handling fleas, ticks (including paralysis ticks), heartworm, and intestinal worms in a single chewable treatment.

Each chew combines afoxolaner and milbemycin oxime: afoxolaner rapidly kills fleas and treats three types of ticks — paralysis, brown dog, and bush ticks — for a full month, while milbemycin prevents heartworm and controls roundworm, hookworm, and whipworm. The beef flavouring is designed to be accepted as a treat, removing the need for spot-on applications or pilling. Suitable for dogs from 8 weeks of age in the 15.1–30kg weight range.

NexGard Spectra's main appeal is consolidation — one monthly chew replaces the separate flea, tick, heartworm, and worming products most households used to run in parallel. The chewable format also sidesteps the common complaints about spot-on residue on furniture and children's hands.
