Heartgard Plus for Dogs is a monthly beef-flavoured chew that prevents heartworm disease while treating and controlling roundworm and hookworm. The 6-pack covers six months of protection and suits owners who want heartworm and basic intestinal worm cover in a single palatable chew.

Each chew combines ivermectin and pyrantel: ivermectin prevents heartworm disease by killing immature heartworm larvae, while pyrantel treats and controls roundworm and four species of hookworm. Made with real beef, the soft chews are designed to be eaten voluntarily as a treat, removing the need to pill or hide the dose. Suitable for puppies from 6 weeks of age.

Heartgard Plus has been one of the most widely prescribed heartworm preventatives in Australia for decades, and its beef-chew format is a big reason why — dogs eat it willingly, which means owners actually stay on schedule. The monthly routine keeps heartworm larvae from ever reaching maturity.
