Heartgard Plus Green is indicated for the prevention of heartworm disease in dogs. It is effective against the immature stages of heartworms (larvae) that are transmitted through mosquito bites.

Heartworm disease is a serious and potentially fatal condition that can affect dogs. It is caused by a parasitic worm called Dirofilaria immitis, which is transmitted through mosquito bites.

Heartgard Plus works by containing the active ingredients ivermectin and pyrantel. Ivermectin helps prevent heartworm disease by allowing the immune system to recognize and inactivate heartworm larvae before they can develop into adults. Pyrantel, on the other hand, treats and controls hookworms and roundworms.

  • Administer monthly: Give your dog the appropriate dosage of Heartgard Plus Green chewable tablet once a month to ensure continuous protection against heartworm disease.
  • Give with or after a meal: Heartgard Plus can be given with or after a meal to help with digestion and absorption.
