Hmmmm. I have to be very frugal these days too (since I moved here). I'm glad it worked. Could be only ironic. If your dog doesn't have heart worms and isn't exposed, then he/she can't get it and preventative meds are a waste of money and, like you said, toxic. We test our dog and no preventative is dispensed. We make her food (she gets some whey from the cheese making for extra calcium cause she's an old bag like me) and she gets crazy exercise with all the other animals. Keeping them healthy helps to prevent the effects of the heartworm. But, I'm not exactly a naturalist and I recommend the faint of heart (pun intended) to use a vet and take their recommendations.
