Hi weezerweeks- Heartgards active ingredient is Ivermectin. Try another brand that contains something like Moxidectin instead. Also I try to use an Ivermectin based HW preventative that does not also do worms. Heartgard Plus for example has some other ingredients for worms that you may also want to avoid.
