Common Heartworm Questions
  1. Does my dog really need to be on a heartworm prevention?
  2. Do we live in a heartworm hot bed?
  3. Do I really need for my dog to be on heartworm prevention year round?

The answer is YES to all three!

In warmer seasons, the number of heartworm cases rises. In the past 12 years you can see heartworm incidences moving into areas where before there were hardly any reported cases. Visit the American Heartworm Society for more information and to view the most recent heartworm incidence maps.

Without the prevention every month your pet could become infected before you know it. The increase of warmer weather throughout the US has done away with the “flea and/or heartworm seasons”. Remember it could be any season, anytime, and anywhere.
