»Laurie O'Keefe DescriptionWhen a mosquito carrying infective heartworm larvae (Dirofilaria immitis) bites a dog, it can transmit infection. The larvae grow, develop and migrate in the body over a period of several months. Mature male and female worms reside in the heart, lungs and blood vessels. The worms mate and the females release their offspring (microfilariae) into the bloodstream. Offspring can be detected in the bloodstream 6-7 months after entering the dog.
