Heartgard Plus Blue for Small Dogs up to 11kg is a monthly beef-flavoured chew that prevents deadly heartworm disease and treats roundworm and hookworm. The blue pack is dosed for the small-breed weight tier, covering puppies and small adults in a single tasty monthly dose.

Each chew combines ivermectin and pyrantel: ivermectin prevents heartworm by killing immature larvae before they can establish, while pyrantel treats and controls roundworm and hookworm infections. The real-beef soft chew is designed to be eaten voluntarily, which makes monthly dosing as simple as offering a treat. Suitable for puppies from 6 weeks of age.

Small dogs are just as susceptible to heartworm as large ones — a single mosquito bite is all it takes. Heartgard Plus's chew format removes the main barrier to consistent monthly prevention, which is getting the dog to actually take the dose.
