Interceptor Spectrum Worming Chews for medium dogs (11 to 22 kilograms) deliver monthly heartworm prevention and broad-spectrum intestinal worm treatment. The yellow-coded chews make dose selection straightforward.

Each chew prevents heartworm infection while treating and controlling roundworm, hookworm, whipworm, and tapeworm. The highly palatable formulation ensures most medium-sized dogs accept their monthly dose without fuss. Provides complete internal parasite coverage in a single, convenient treatment.

Interceptor Spectrum has earned veterinary trust for its comprehensive worm coverage that goes beyond basic roundworm and hookworm to include tapeworm — a gap in many competing products.
