NexGard Spectra for dogs 30.1–60kg is a monthly beef-flavoured chew sized for extra-large and giant breed dogs. The 3-pack covers three months of comprehensive parasite protection — fleas, ticks, heartworm, and intestinal worms — in a single chew each month, suited to the breeds that need the highest weight-tier dose.

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 and treats roundworm, hookworm, and whipworm. The top weight tier ensures extra-large dogs receive a properly calibrated dose rather than doubling up on lower-tier chews. Suitable for dogs from 8 weeks of age.

Extra-large dogs are the hardest to dose with topical spot-ons — the coat is thicker, the surface area larger, and residue management more difficult. A single chew that handles the full spectrum makes monthly parasite control significantly easier for giant-breed households.
