What over the counter monthly heartworm/parasite medication would you recommend? I can't afford to buy it from my vet at the moment.

Hi there. Unfortunately, there are no heartworm preventatives that are available over-the-counter - by definition, these are prescription products. But, you can certainly choose to order them through an online pharmacy like 1-800-PetMeds or Chewy.com if you like, as these may be less expensive than purchasing through your vet's office. Your veterinarian should be able to give you a prescription to have filled at any pharmacy you choose, as long as your pet has had an exam within the past year. :)
