You don't do ANY heartworm preventative? Not even ivermectin which can be bought over the counter in some states? (PLEASE unexperienced people do NOT just go out & give this to your dogs without having the dog tested and an ok from your vet. Giving your pet a heartworm preventative if the dog is positive may cause death) Do you at least get them tested every year or two?Originally Posted by .sarah
