As the heartworms
die and lose their attachment to the interior of the dog's heart, lungs, and pulmonary arteries, and as their bodies are released into the bloodstream, the decaying fragments are deposited into the alveoli, where they can plug up the bronchioles and cause tissue death in the lungs.
The statement you refer to should have read, "If your dog does not have heartworms

Cats should be tested for heartworms

. This will reduce the possibility of the infection being passed to other dogs through mosquitoes, shorten the lifespan of the adult worms, and lessen the chance of adverse side effects from worm death.
Infestation with fleas, ticks, mites, a variety of intestinal worms, and other nasty little critters such as heartworms
are more likely then.
