Those who love their dogs
, too much to leave them ashore, and expecting to take them cruising, should consider the implications of heartworm.
Heartworm infestation is dangerous; untreated dogs
die and treated dogs go through weeks of discomfort while the worms are killed and expelled from their bodies.
Although at one time confined to more southern climates, heartworm has now spread to nearly all climates where its vector, the mosquito, is found. Heartworm disease is now present on every continent except Antarctica, and occurs where these four factors are found:
* a susceptible host population
* a stable reservoir of the disease
* a stable population of vector species
* a climate that supports the parasite’s life cycle
