With winter at our doorsteps, we commonly get asked “does my pet need heartworm protection in the winter?” The answer to this question is…absolutely! Here’s why:
Heartworm disease is spread by mosquitoes. You never know when that last mosquito will die for the season…or when the first one will hatch in the spring. Furthermore, if the temperature gets a little warm (over 50F), mosquitoes may be able to come out of hibernation. Heartworm prevention works in a completely different manner than flea and tick prevention. Heartworm prevention kills the baby heartworms that the pet has been exposed to over the last month. So if you miss a dose, any heartworms your pet was exposed to over the last month have the opportunity to grow to adulthood. The preventatives only kill the baby worms. Heartworm preventatives also have other benefits. Most of them kill many intestinal parasites every month as well.
We have a variety of heartworm preventatives, and our doctor can help you pick the one that is right for your pet! Call us if you have questions or would like more information!
