I use Ivermec daily for all 6 of my dogs. It is SO much cheaper and effective. It is the main ingrediant in heartworm medications. I got started on it from my vet b/c one of my guys had demodex for a few months and once I realized the savings of using it, I just switched all my babies to it! You can get it from any farm supply store. Just make sure you knwo your dosage!!
