In experimentally induced infections of heartworms in dogs, the proportion of infective larvae developing to adults is high (40% to 90%). However, the proportion of infected dogs from which mature worms have been recovered is almost 100%. The number of worms infecting a puppy can be very high, with the amount of worms in dogs ranging from one to around 250.Microfilaremia, the presence of heartworm offspring in the blood of infected dogs, is comparatively common. However, not all heartworm infections result in these offspring circulating in blood. These are known as occult heartworm infections and might be the result of a number of factors such as single sex heartworm infections, host immune reactions affecting the presence of circulating offspring (microfilariae) and most significantly, the management of heartworm preventives.
