Over-the-counter Heartworm Preventative?

My 9-year-old Corgi is officially on her last month of Heartworm preventative and I'm hoping that I can avoid the excessive fees charged by all of the local vets in my area to get my hands on more. Can I buy it online, or do I have to have a prescription from a vet? I checked Amazon.com, but they don't have any. I know that you can buy flea medication for double your dog's weight and actually get 6-months of treatment instead of 3 for nearly the same price, is it the same with heartworm pills? Can I just cut the pills in half?

I would also love to hear about any flea, tick, AND heartworm 3-in-1 treatments, if anyone has had good results with one that I can get online/in a store.

You can purchase heartworm preventative online. I get mine from Drs. Fosters & Smith. You can also get it from 1-800-pet-meds.

Lastly, heartworm preventative can only be purchased with a prescription. There is no OTC heartworm preventative product.

BTW, I haven't bought my heartworm preventative from my vet for over 20 years. My current vet, doesn't even carry it, she'll fax a prescription to where I choose to get it from.

As for flea & tick, you do not need a prescription. I use K9AdvantixII. I also get that from Drs. Fosters & Smith.
