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.
Puppies under 7 months of age can be started on heartworm prevention without a heartworm test (it takes at least 6 months for a dog to test positive after it has been infected), but should be tested 6 months after your initial visit, tested again 6 months later and yearly after that to ensure they are heartworm-free.
