I have kept my dogs on heartworm prevention all year round for many years. It alleviates the need for yearly testing. Now we test every two years.
One thing that many people don't know, certainly I didn't know for a long time, is that heart worm prevention works backwards, not forward. In other words, if you give your dog his dose on April 1, it takes care of what may have bit him the previous 30 days. Where we would all think that the April 1 dosage would be for April 1-30th.
