What is Heartworm? Heartworm is a parasitic infection that affects dogs and can be potentially fatal if left untreated. It is caused by a type of worm called Dirofilaria immitis, which is transmitted through mosquito bites. When an infected mosquito bites a dog, it injects microscopic larvae into the dog's bloodstream. These larvae then migrate to the heart and lungs, where they mature into adult worms. Over time, the presence of these worms can cause severe damage to the dog's organs and can even lead to heart failure. It is important for dog owners to be aware of the causes, symptoms, and treatment options for heartworm in order to protect their pets from this serious condition. How is Heartworm transmitted to dogs? Heartworm is transmitted to dogs through mosquito bites. When an infected mosquito bites a dog, it injects microscopic larvae into the dog's bloodstream.
