Dear Readers: If you have a dog, it should be on a HEARTWORM preventative medication no matter where you live. It used to be that if you lived in areas with harsh winters, you didn't have to give the pet the medication during the winter months. Now, the American Heartworm Society says you should give your pet heartworm medication all year long. The disease can still be spread by wildlife or when you travel with your pet. Pets become infected when they are bitten by mosquitoes that are carrying the parasite.
