I recently took Lacy to her new vet and asked the same thing. She's been on heartguard every month since 3 months old. First of all, in Texas the vet you're using can't sell Heartworm preventative unless they have a negative heartworm test on file for your dog. I'm sure you can find some vets that will but most won't. If your dog does happen to have heartworms and you give them the preventative, you can kill your dog. Also they told me nothing is 100% effective. Heartguard guarantees it's product if you are on it every month and have a heartworm test once a year. If for some reason your dog does contract heartworms, the company will pay for the treatment. Really it's better to be safe than sorry...
