For pups six months old or older that haven't been on preventative, a heartworm test should be given before starting medication and the dog tested six months later to be sure there are no parasites. Annual tests thereafter ensure your puppy stays healthy.
I like to start heartworm prevention at some point during the puppy series of vaccines (8-10 weeks of age). The puppies do not have to be tested first because the life cycle has not had time to develop. Past 6-7 months of age, the dog should be tested prior to starting heartworm prevention.
