All you need are mosquitos for a dog to get heartworm. We buy the horse ivermectin from Dels, a certain cc for every so many pounds - it is much cheaper in the long run. Inject it in a bread ball every month. I am hoping that this also prevents them from getting rat lung worm, or angiostrongylus cantonensis, from eating slugs or snails. This medication is also an anti helminth that is given to people who have rat lung worm.
