Heartgard Plus is a monthly beef-flavoured soft chew for small dogs up to 11kg. It's primarily a heartworm preventative, and also treats and controls roundworms and four species of hookworms — addressing the core internal parasites in Australian dogs with a single monthly dose. The soft chew format is accepted by most dogs without resistance.

Heartworm prevention works by eliminating immature larvae before they can develop into adult worms — this is a preventative, not a treatment for existing infection, so consistent monthly dosing matters. The formula tackles roundworms and hookworms alongside heartworm, simplifying internal parasite management for small dogs. Real beef in the formulation supports palatability even in dogs that usually resist medication.

Heartgard Plus suits owners who want straightforward internal parasite coverage without juggling multiple products. The monthly cadence is easy to maintain, the soft chew is accepted by most dogs, and the coverage across heartworm, roundworms, and hookworms handles the primary internal parasite risks in one go.
