Interceptor Spectrum for large dogs (22 to 45 kilograms) is a monthly tasty chew providing comprehensive heartworm and intestinal worm protection. The blue-coded 3-pack covers three months of broad-spectrum parasite prevention.

Each chew prevents heartworm disease and treats five types of intestinal worms: roundworm, hookworm, whipworm, and tapeworm. The palatable format means most large breed dogs accept their dose readily. Precisely dosed for dogs in the 22 to 45 kilogram weight range.

Interceptor Spectrum is a veterinary favourite for its combination of heartworm prevention with the broadest intestinal worm coverage available in a single monthly chew.
