NexGard Spectra for small dogs 3.6-7.5kg (yellow pack) is a monthly beef-flavoured chew that combines external and internal parasite protection in a single dose. It is suitable for dogs from eight weeks of age and is dosed strictly by bodyweight, so the yellow variant is matched to the small size bracket rather than being interchangeable across the range.

Each chew treats and controls fleas, three species of ticks including the paralysis tick, plus mites and lice, and it also covers heartworm prevention and the main intestinal worms including roundworm, hookworm, and whipworm. Fleas begin to die within hours, and the single monthly dose replaces having to layer a separate flea, worm, and heartworm product on different schedules.

Owners choose NexGard Spectra when they want one product on the calendar instead of three. The beef-flavoured chew is given like a treat, which sidesteps the wrestling match that comes with spot-on liquids and tablets, and the all-in-one coverage is the main reason vets recommend it for small breeds.
