Discovering Heartworm Disease in Dogs

Heartworm is more than a buzzword; it's a serious disease that can affect any dog, from Chihuahuas to Great Danes. No state in the U.S. is heartworm-free, and areas with high mosquito populations see more cases. It spreads through mosquito bites and can harm your dog's health long-term. As veterinarians, we've seen its impact on dogs and their owners. This guide covers what heartworm is, how it's transmitted, symptoms, prognosis, and most importantly, prevention and treatment.
