Heartworms are long, spaghetti-like, white-colored parasitic worms known as Dirofilaria immitis. They grow up to a foot in length and live inside the lungs, heart, and associated blood vessels of a dog for several years. These deadly worms reproduce within the heart, interrupt the normal functioning of the heart, and lead to death if left unattended.
Heartworms are transmitted to dogs by an infected mosquito. When a mosquito bites an infected dog, it ingests immature heartworm larvae (microfilariae), which grow within the infected mosquito within 10 to 30 days. When this infected mosquito bites a healthy dog, heartworm larvae are transmitted into the dog's bloodstream and reach the heart. These worms grow and reproduce within the heart, causing dangerous heartworm disease. Let's learn more about the life stages of heartworms.
