Heartworm disease is responsible for infecting thousands of dogs and cats every year. This disease is potentially fatal yet completely preventable. Heartworm affects both dogs and cats, however, dogs do have an increased risk of developing this disease, especially those that live outdoors.
What causes heartworm disease?
Heartworm disease is caused by a blood parasite that is spread by mosquitoes. These heartworms migrate through the tissue until they enter the vascular system. Once infected, these nasty parasites reside and live on the right side of the lungs and pulmonary arteries where they obstruct the flow of blood to the heart affecting the rest of the body. By the time heartworms reach the lungs, they are mature and can grow to be as long as 14 inches. Hundreds could be living at one time.
