Some vets test first for heartworm before giving the heartworm meds and some dont. Mine didnt. I now buy my flea protection Advantage on Ebay. The heartworm meds on Dr Fosters and Smith you still need a prescription from your vet. I found a place in Australia where you can buy the heartworm meds much cheaper without a prescrition. I will try to find the link and post it. I am going to buy mine from there and save $$ |
