Heartgard Plus Worming Treatment for dogs 23–45kg in the 6-pack is a six-month supply of monthly beef-flavoured chews that prevent heartworm disease and treat roundworm and hookworm. Dosed for the large-breed weight tier, it provides consistent half-year protection in a single purchase.

Each soft chew combines ivermectin and pyrantel: ivermectin kills immature heartworm larvae before they can establish disease, while pyrantel handles roundworm and four species of hookworm. Made with real beef, the chews are designed to be eaten voluntarily — no hiding in food or wrestling with pills. Suitable for puppies and adult dogs from 6 weeks of age.

Heartworm prevention works best when it's maintained without gaps, and a 6-pack removes the purchase intervals that can lead to missed months. The combination of heartworm and intestinal worm coverage keeps the monthly routine straightforward.
