NexGard SPECTRA for Medium Dogs 7.6-15kg (Green) is a beef-flavoured monthly chew that covers fleas, ticks, mange mites, biting lice, heartworm and intestinal worms in a single all-in-one product. It's designed for adult dogs and older puppies in the mid-range weight band.

One chew per month kills adult fleas rapidly, treats and controls paralysis ticks for a full month, and covers demodectic and sarcoptic mange mites plus biting lice. It prevents heartworm disease and also treats and controls roundworm, hookworm and whipworm. The beef flavour is designed to be taken as a treat rather than hidden in food, and dosing is weight-based, with the green pack calibrated for 7.6 to 15 kilogram dogs.

NexGard SPECTRA Green is one of the most widely sold dose sizes in the range because it covers many common mid-sized breeds, including Border Collies, Cavoodles, Kelpies and Staffies. Owners stick with it because a single chew replaces stacking separate flea, tick, heartworm and worming products.
