Interceptor Spectrum is a monthly worming chew for medium dogs weighing 11–22 kg. Each flavoured chew provides broad-spectrum protection against heartworm and intestinal worms, covering multiple parasite types in a single monthly dose — a practical foundation for routine parasite prevention in medium-sized dogs.

Each monthly chew covers both heartworm prevention and intestinal worm treatment in a single dose. The flavoured format means most dogs will accept it without needing to be disguised in food. The yellow packaging identifies the medium-dog concentration for the 11–22 kg bracket, which helps avoid dosing confusion in households with multiple dogs of different sizes.

The monthly schedule and chewable format make Interceptor Spectrum a low-friction addition to a dog's routine. Once-a-month dosing is easy to track, and the single treatment covering multiple parasite types means less complexity for owners managing regular parasite prevention.
