Heartworm In Winter?
If your veterinarian has your dog on year-round heartworm medication, and you live in a state where the birds actually fly south for the winter, you might want to consider changing vets or at least not following his or her advice on this matter.
Here's why: heartworm can only be transmitted to a dog if the heartworm nematode has completed the first part of its lifecycle inside the body of a mosquito. The first part of that lifecycle can only be completed if the temperature stays above 57 degrees for at least 45 days straight, both day and night.
