Does My Dog Need Heartworm Prevention in Winter in Oxford, MS?

Yes—keep your dog’s prescribed heartworm prevention going all year. A cooler day in Oxford is not a reason to skip a dose. The FDA recommends year-round protection, including winter.

Why does winter prevention matter?

Infected mosquitoes spread heartworms. Fewer mosquitoes in winter does not eliminate the risk, and heartworm disease can seriously damage a dog’s heart and lungs. Prevention is easier than treating an established infection.

For Oxford families, make prevention part of your regular pet-care routine rather than deciding dose by dose based on the weather. Put a reminder on your calendar and check your supply before it runs out.

What if my dog misses a dose?

Use a heartworm preventive prescribed for your dog’s weight and health needs. If you missed a dose or stopped treatment, call your veterinarian for a restart and testing plan rather than guessing or doubling up.

Dogs should also receive annual heartworm testing, even when they take prevention consistently.
