Heartworm preventatives work retroactively. This means they work backwards to protect your pet from disease they may have been exposed to in the previous months. Because of this, the American Heartworm Society recommends giving heartworm preventative 3 months after the first frost. By that time in Minnesota we start warming up again. Therefore, we recommend giving heartworm preventative year-round. Pledge to protect your pet's heart every 30 days!
