Really? That is interesting, and hard to believe, since ivermec has the same active ingredient in heartguard which is ivermectin. I think a lot of vets just want you to buy heartguard from them for lots of $$$
Hello everyone!! I am new to this forum; I recently read a tread from last year about using cattle/swine Ivomec to prevent heartworm in dogs. I am wondering if anyone has any experience using a cattle/swine/poultry product to control fleas on their dog(s)??
