After the 30 day rest period,
your dog will come in for a difil test. This is a blood test to make sure
that any heartworm larvae produced by the dying heartworms have been
eliminated. If the test is negative, then your dog can be started on a
monthly heartworm preventative. If the test is positive, then we will
administer an injection of ivermectin to kill any remaining larvae, and
start your dog on a monthly heartworm preventative.
