WHAT IS DOG HEARTWORM DISEASE AND HOW IS IT CONTRACTED
Heartworm disease is caused by a parasitic worm called Dirofilaria immitis. These worms can live inside, and be transmitted by, as many as 30 different species of mosquitos. They are carried by the mosquitos and spread when a dog or other pet is bitten by an infected mosquito. The Microfilariae, an early lifecycle stage of this parasitic worm, must pass through a mosquito in order to become infective larvae. Once transmitted to a dog through a mosquito bite, they will mature into adults within about 7 months. They will then mate and reproduce while living inside the dog.
Heartworm worms are called “heartworms” because the adult worms live inside an infected dog's heart, lungs, and corresponding blood vessels. They can live inside your dog for as many as 7 years!
