The first published description of heartworm in a dog appeared in the 1847 issue of the Western
Journal of Medicine and Surgery. After all this time, heartworm still plagues dogs across
the country.

"Despite improved
diagnostic methods, effective preventatives and increasing awareness among veterinary
professionals and pet owners, cases of infection continue to appear in dogs... around the
world."

The truth about heartworm disease is:
-
It is still a serious and potentially fatal threat; it is not under control as some would
believe.
-
The infection rate remains unchanged over the past ten years, despite tremendous awareness of
heartworm disease.
-
An estimated 250,000 dogs and cats tested positive for heartworm infection in 2004. This is up
slightly from a 2001 survey.
-
Approximately one-half of U.S. dog-owning households are not using heartworm preventatives.
-
The most common signs of heartworm disease are hidden.

"It is important to know
the heartworm status of your patients so an informed approach to therapy can be devised."
|
|
 |

Therefore, all dogs should be screened:
-
Routinely in endemic areas
-
Once a year when going on preventatives (according to manufacturers' instructions)
-
Routinely in non-endemic areas due to the mobility of owners and pets
The good news is—you can diagnose and treat infection early in your patients,
before severe damage has occurred. View A
Clinical Approach to Heartworm Infection
or review treatment protocols available from the American
Heart Society.
