Heartgard Plus 0–11kg Small Blue is a monthly beef-flavoured heartworm chew for small dogs and puppies. The blue pack is dosed for the lightest weight tier, covering toy breeds and young puppies whose heartworm prevention needs a properly calibrated small-dog dose.

Each chew delivers ivermectin and pyrantel: ivermectin prevents heartworm by killing larvae before they can mature, while pyrantel treats roundworm and hookworm. The soft beef chew is designed to be taken as a treat, removing the dosing challenges that come with pilling small or fussy dogs. Suitable from 6 weeks of age.

Heartworm doesn't discriminate by size — small dogs are just as vulnerable as large ones. A properly dosed small-dog chew ensures consistent protection without the risks of splitting larger doses or under-treating lightweight animals.
