Mosquito Diseases - Dog Heartworm
What is heartworm disease?
Thirty known species of mosquitoes transmit heartworms. The female mosquito becomes infected by biting the infected dog and ingesting the heartworm microfilariae. The microfilariae develop for 10 to 30 days in the mosquito and are then transmitted to the next dog that it bites. When fully developed, the infective larvae enter the dog’s bloodstream and move to the heart and adjacent vessels where they grow. Within two to three months they start reproducing within the dog’s vessels.
It is important to note that heartworms are not transmitted from dog to dog. It is the female mosquito that acts as the intermediary host, transmitting the disease to canine victims.
