Heartgard Plus Chewables are monthly beef-flavoured heartworm prevention chews for dogs. Each dose prevents deadly heartworm disease while treating and controlling roundworm and hookworm — a compact monthly routine that covers the most critical internal parasite threats.

Each chew combines ivermectin and pyrantel: ivermectin kills immature heartworm larvae delivered by mosquito bites, preventing them from developing into adult worms, while pyrantel treats roundworm and hookworm. The beef flavouring is designed to make dogs accept the dose willingly. Available across weight tiers so every dog from toy to giant gets a properly calibrated dose.

Heartgard Plus is one of the most commonly recommended heartworm products in Australian vet clinics, and its palatability is the practical factor that makes it work — dogs eat it willingly, so owners stay on schedule. The monthly cadence matches the heartworm larval development window.
