Heartworm disease is not contagious, meaning that a dog cannot catch the disease from being near an infected dog. See a graphic of the heartworm lifecycle in dogs. The adult heartworms mate and the females release their offspring into the dog’s bloodstream, completing the lifecycle. In the newly infected dog, it takes about 6 to 7 months for the infective larvae to mature into adult heartworms. When the infected mosquito bites another dog, the mosquito spreads the infective larvae to the dog through the bite wound. Microfilariae must pass through a mosquito to become infective larvae. Over the next 10 to 14 days and under the right environmental conditions, the microfilariae become infective larvae while living inside the mosquito. When a mosquito bites the infected dog, the mosquito becomes infected with the microfilariae. In an infected dog, adult female heartworms release their offspring, called microfilariae, into the dog’s bloodstream. In the United States, heartworm disease is most common along the Atlantic and Gulf coasts from the Gulf of Mexico to New Jersey and along the Mississippi River and its major tributaries, but it has been reported in dogs in all 50 states. The worms are called “heartworms” because the adults live in the heart, lungs, and associated blood vessels of an infected animal. The mosquito is the intermediate host, meaning that the worms live inside a mosquito for a short transition period in order to become infective (able to cause heartworm disease). The dog is the definitive host, meaning that the worms mature into adults, mate, and produce offspring while living inside a dog. It is caused by a parasitic worm called Dirofilaria immitis.The worms are spread through the bite of a mosquito.
