Heartworm Prevention Is Much Better Than The Cure
Heartworm is a particularly nasty parasite which is spread from host to host by mosquitoes. Dog heartworms are a kind of filaris (a long thin worm), but the condition can affect cats, ferrets, coyotes, wolves, sea lions and even humans. This worm was named as such due to its habit in the final stage of its reproductive cycle to live in the heart of its host.
