Year-Round Protection Is Essential

Many pet owners might assume that they only need to give their dog heartworm disease preventives during warmer months (mosquito weather). While heartworm transmission can decrease in winter months, the risk of infection is always there.4 Consistent, year-round dosing avoids gaps in protection that would leave him vulnerable to heartworm disease. That’s why it is so important to give your dog HEARTGARD Plus chews each and every month for year-round protection.
