NexGard Spectra for Large Breed Dogs 15.1–30kg is a monthly beef-flavoured chew providing all-in-one parasite protection in a convenient 3-pack. Designed for the standard large-breed weight band, it covers fleas, ticks, mites, lice, heartworm, and intestinal worms — the broadest coverage available in a single monthly chewable.

Each chew combines afoxolaner and milbemycin oxime: afoxolaner kills fleas rapidly and controls paralysis ticks, brown dog ticks, and bush ticks for a full month, while milbemycin prevents heartworm disease and treats roundworm, hookworm, and whipworm. The comprehensive formulation means owners running separate flea, tick, and worming products can consolidate to a single monthly chew. Suitable for dogs from 8 weeks of age in the 15.1–30kg range.

Large-breed dogs spend more time outdoors and pick up more parasites, making consistent monthly cover non-negotiable. NexGard Spectra's chewable format removes the common frustrations of spot-on treatments on big coats — no parting fur, no wet residue, no post-application avoidance period.
