Heartworm Testing and Prevention
DVPH follows the recommendations of the National Heartworm Symposium.
- For our geographic region, we recommend all puppies begin monthly heartworm medicine by 16 weeks of age.
- Heartworm medications need to be given year round.
- As added protection, heartworm testing (a simple blood test) is advised annually, even with year-round prevention, at the time of routine vaccinations.
