Beware Of Increased Heartworm Risk To Dogs After Hurricane Irma & Other Major Storms

Heartworm disease is a worm parasite that infects the heart and lungs of dogs. The disease has devastating consequences for positive dogs as the worm damages heart and lungs tissues leaving the infected dog prone to clots, inflammatory lung and heart disease, and eventually heart failure.  The disease is spread by the bite of an infected mosquito when it feeds on a canine host.

Mosquitoes reproduce in fresh or brackish, standing water and moist soil.  The female lays her eggs in water and wet or moist soil daily during her 4-8 week lifespan.  The eggs hatch into larvae, form into a pupa, then emerge into an adult mosquito in about 2 weeks.  This is why in the aftermath of mass flooding events like hurricanes mosquito blooms occur within a couple of weeks after the storm clears out.  With this massive increase in the overall numbers of the insect vector by which heartworm is spread, heartworm risk greatly increases in the months following tropical storms and hurricanes.

While heartworm is a year round risk in Florida and year round prevention is strongly advised, it is especially critical to administer timely heartworm prevention medication in the months following a major tropical storm or hurricane.  Luckily, heartworm prevention medications are both safe and affordable, with most products administered orally or topically on a monthly basis (with the exception ProHeart, which is administered by injection once every 6 months).

In the aftermath of bad storms like Irma, countless Floridians have to deal with loss of homes, businesses and tragically even loss of life.  In the midst of so much stress and calamity, it can be easy to forget to administer monthly heartworm prevention to your dog(s) with so much to cope with in the aftermath of a storm.  Therefore, with potentially tragic health circumstances to dogs if forgotten, in addition to offering well wishes to all who experienced Hurricane Irma, I also offer this friendly reminder to keep all of your dogs current on their heartworm medication.
