Many pet parents believe that once the cold weather hits, parasites disappear. Unfortunately… that’s a myth…they don’t! Even during our Midwest winters, intestinal parasites and heartworm remain a substantial risk for dogs and cats.
Intestinal Parasites including roundworms, whipworms, hookworms, and giardia can survive in soil, frozen ground, and indoor environments. Pets can still be exposed to parasites on winter walks, in yards, at dog parks, or even from wildlife passing through the backyard. And because pets tend to spend more time indoors during the winter, parasite transmission rates inside multi-pet homes can actually increase.
Pet owners also tend to think less about heartworm in the winter, because we don’t see mosquitoes every day, but mosquitoes don’t magically die off. Many survive in garages, basements, barns, under leaf litter, and tend to emerge during warm spells throughout the winter. Just one mosquito can transmit heartworm, which is much more expensive (and dangerous) to treat than to prevent.
Bottom Line: Continue Prevention Year-Round
Don’t pause preventive meds just because of snow or cold weather. Year-round parasite and heartworm prevention, combined with regular vet check-ups, is the safest approach, especially now that mosquito seasons and parasite risk periods are expanding.
If you’re unsure which prevention is right for your pet, or if you’ve missed some doses, we’re happy to help get you back on track. Stay warm and keep those pets protected!
