Heartgard Plus is safe for dogs and puppies 6 weeks of age and older and is safe to use in pregnant and nursing dogs.
What is the difference between Heartgard Plus and Heartgard?
Heartgard Plus contains ivermectin and pyrantel. Heartgard tablets contain only ivermectin. Both products prevent heartworm disease in exactly the same way and with the same reliability, when dosed once a month as recommended. However, Heartgard Plus also controls roundworms and hookworms in dogs, due to the added ingredient. When using Heartgard, it may therefore be necessary to treat for these intestinal worms also, as advised by your veterinarian.
