NexGard Spectra is a monthly beef-flavoured chew for large dogs weighing 15.1 to 30kg. Each dose protects against fleas, ticks, mites, lice, heartworm, and intestinal worms — the full spectrum of common parasite threats in a single treatment. It suits large breeds like Labradors, Kelpies, and Golden Retrievers, and is available in 3-pack and 6-pack formats.

The combination of afoxolaner and milbemycin oxime drives the dual action. Afoxolaner targets the nervous systems of fleas and ticks, killing them rapidly; milbemycin oxime prevents heartworm disease and treats roundworms, hookworms, and whipworms. The soft beef-flavoured chew is accepted by most dogs without any disguising — no pill pocket required. Because some intestinal parasites can transfer to humans, consistent monthly dosing also reduces household exposure risk.

Owners who consolidate parasite prevention into a single monthly product tend to stick with the routine — fewer steps means fewer missed doses. NexGard Spectra is a practical choice for large breed households managing both internal and external parasite risk year-round.
