Q. Is there something I can buy over the counter at Walmart for heartworm? I don't have the money for a prescription

A. Prior to starting any heartworm medication, your dog must have a negative heartworm test. This can be done at a local clinic in your area. Heartworm medications are usually prescription only and require a prescription from your local veterinarian. However if you are looking to find these medications at a lower cost than your vet clinic offers, many websites such as 1800PetMeds and DrsFosterSmith offer these products at a reduced rate. Since these products are prescription-only, you will need to have your vet fax over the prescription before they can mail you the medication. However, many vets are very happy to do this in order to provide medication for you at a lower cost!
