Heartgard Plus Green for Medium Dogs 12–22kg is a monthly beef-flavoured chew that prevents heartworm disease and treats roundworm and hookworm. The colour-coded green pack covers the standard medium weight tier and suits owners running a monthly heartworm prevention routine.

Each chew combines ivermectin and pyrantel: ivermectin kills immature heartworm larvae before they can develop, while pyrantel treats and controls roundworm and four species of hookworm. The beef-flavoured soft chew is designed to be taken as a treat, which removes the need for pilling. Vet-recommended and suitable for puppies from 6 weeks of age in the 12–22kg weight band.

Monthly heartworm prevention is one of those non-negotiable routines in Australian dog care, and Heartgard Plus is consistently one of the easiest products to maintain it with — dogs accept the chew willingly, and the colour-coded packs make weight-tier selection straightforward.
