Most puppies should be started on a heartworm preventative at least by two months of age. And now in most areas of the United States, it is recommended that heartworm preventative be given all year long, although the risk of getting heartworms is still greatest in the summer months. Heartworm preventative is usually given monthly in the form of a chewable tablet. The most popular brands are Heartgard and Interceptor. It is important the you give this tablet every month. Please note that if your German Shepherd Puppy goes 6 months without heartworm prevention, consult your local veterinarian. Blood testing will be required before administering heartworm preventative.
