Heartworm is a common parasite in dogs, cats, ferrets, and several mammal species. During National Heartworm Prevention Month, we urge you to learn more about the transmission, symptoms, and treatment of this parasite. Left untreated, heartworm disease can cause serious illness or the death of your beloved pet.
What is a Heartworm and How Does It Get Inside Your Pet?
A heartworm is approximately 12 inches long and lives inside the blood vessels, heart, and lungs of animals who are infected with it. The most typical course of transmission is through a mosquito. When a female heartworm is present inside of a dog or cat, she can reproduce thousands of microscopic worms that travel to the bloodstream. A mosquito ingests some of these baby worms when it stings an infected pet and feeds on his blood. Heartworm transmission occurs the next time the mosquito bites a pet.
