NexGard Spectra for medium dogs is a monthly beef-flavoured chew that covers fleas, ticks, mites, intestinal worms, and heartworm in a single dose. This pack is sized for dogs weighing 7.6 to 15kg. It is a prescription-strength parasiticide and should be used according to the dosing schedule for the dog's weight band.

The active combination (afoxolaner and milbemycin oxime) kills fleas rapidly, controls paralysis ticks for a full month, and treats roundworm, hookworm, whipworm, and heartworm. Coverage extends to mites involved in mange and ear mite infestations. Because it is an oral chew rather than a topical, there is nothing to wash off after bathing or swimming, and no residue on coats or furniture.

Owners typically choose Spectra when they want one product covering paralysis tick country, heartworm, and intestinal worms rather than stacking separate treatments. The beef chew format also makes monthly dosing straightforward for dogs that resist tablets or spot-ons.
