Banfield Survey Highlights Gaps in Heartworm Prevention Awareness Among Pet Owners

Key findings from the survey show that almost 30% of pets are not on any form of heartworm prevention. Additionally, 21% of pet owners erroneously believe that mosquitoes in their regions do not carry the parasite, despite heartworm cases being reported in all 50 states. Furthermore, 41% of those surveyed think that heartworm is only a seasonal threat, leading 51% to skip year-round prevention; among those, 18% use prevention only during spring and summer.

These statistics alarm veterinary professionals, especially given the rising incidence of heartworm disease, which is entirely preventable with appropriate year-round medication. Dr. Alea Harrison, chief medical officer at Banfield, noted that heartworm infection rates continue to climb nationwide, even as preventative measures are generally safer, easier, and more affordable than treatment for existing infections.

According to the American Heartworm Society (AHS), heartworm cases are increasing not only in traditional hot spots but also in areas where the disease was once uncommon. Dr. Jennifer Rizzo, AHS president, emphasized that states with the highest incidences include Mississippi, Louisiana, Texas, Alabama, and Arkansas, with several states experiencing a rise in high-density heartworm areas.

Previously less affected states like Washington, Oregon, and Massachusetts have also reported increased prevalence. For example, Delaware saw a 299% rise in heartworm rates over the past five years, with Montana and Nevada following closely behind at 140% and 101%, respectively. Banfield's records indicate a 47% increase in heartworm diagnoses among cats over the same period.

The survey results stress the importance of ongoing education for pet owners about the necessity of year-round parasite prevention.
