How Often Should I Get My Dog Checked for Heartworms?

Frequency of Heartworm Checks for Dogs

It is recommended to have your dog checked for heartworms at least once a year, even if they are on preventive medication. In areas where heartworm disease is more prevalent, such as in warmer climates or regions with high mosquito populations, vets may suggest more frequent testing. Puppies should be tested for heartworms as early as 7 months of age and then retested 6 months later. Regular testing helps ensure early detection and treatment if your dog does contract heartworms.
