NexGard Spectra is a monthly beef-flavoured chew that covers fleas, ticks, heartworm and intestinal worms in one dose. This pack is dosed for small dogs weighing 3.6 to 7.5kg — check your dog's current weight before buying, as the dosage bracket matters for both efficacy and safety.

The active ingredients afoxolaner and milbemycin oxime start killing fleas within hours and control paralysis ticks, brown dog ticks and bush ticks alongside roundworm, hookworm, whipworm and heartworm. One chew a month replaces the usual stack of a spot-on plus a heartworm tablet plus a wormer, which is the main appeal for owners juggling multiple parasite products. The beef flavour means most dogs take it as a treat.

Owners tend to move to NexGard Spectra when they're tired of pinning the dog down for a spot-on or splitting a wormer into a bit of cheese. Consolidating flea, tick and worm cover into a single monthly chew is simpler to remember and easier to administer, which in practice means fewer missed doses.
