NexGard Spectra for extra-small dogs (2–3.5kg) is a monthly beef-flavoured chew that covers fleas, ticks, mites, heartworm and intestinal worms in one dose. The orange pack is sized specifically for toy breeds and small puppies from 8 weeks of age, replacing several separate parasite products with a single monthly treat.

Each chew rapidly kills fleas and treats three tick species including the paralysis tick, alongside sarcoptic mange and demodex mites. It also treats roundworm, hookworm and whipworm, and prevents heartworm disease when given monthly year-round. The beef flavouring is designed to be accepted like a treat rather than fought over as a tablet, which matters more with a wriggly 3kg dog than most owners expect.

Owners choose Spectra when they want one product instead of a shelf of them. Consolidating flea, tick, worm and heartworm cover into a single monthly chew reduces missed doses, and the small-dog dosing means no splitting or estimating from a larger pack.
