Heartworm disease is becoming well
established in Oregon. Heartworm
disease is spread by mosquitoes. The
process of transmission starts with
a mosquito biting an infected
animal. The mosquito then draws up
the heartworm microfliaria (babies)
and bites another animal, depositing
the microfliaria in to that animal.
The
worms grow up over a six-month
period and live in the heart. The
worms are about the size of a
ballpoint pen refill (approximately
3-6 inches long). They cause
problems with the circulation and
lungs. Dogs are the primary hosts
for this worm, although cats can
become infected. The reason it is
spreading across Oregon is the
coyote. Coyotes are a reservoir as
they are becoming infected and not
being treated.
Another source of infection is if a
dog in your neighborhood becomes a
carrier. The good news is that
heartworm disease is very easy to
prevent. Simply test your dog and if
they do not have heartworm disease,
start them on a monthly preventive.
Ask for Sentinel, Heartgard or
Interceptor, they are all chewable.
Revolution is a topical flea
medication that also carries
heartworm disease protection. Most
of these medications can’t be given
without a test because if an animal
has heartworm disease and is given a
preventive it can be detrimental.
Some of the medications also protect
against intestinal parasites
(worms). Humans do not get
heartworms but have been known to
get nodules on the lungs. |
