What is Heartworm Disease? • Heartworm disease is a serious disease that results in lung, heart and other organ failure. • Heartworm disease is spread through ONE bite of a mosquito on a dog that is not on heartworm preventive.
Heartworm Disease Facts Heartworms live in the right side of the heart Significant damage is done before pets show signs or symptoms Heartworm disease is detected by a small blood sample taken at your Vets Office • Heartworms that live in the lungs or blood vessels can grow more than 12 inches long • Heartworm parasites live between 5-7 years in a dog • The parasites are transmitted from one dog to another by the bite of an infected mosquito
Lifecycle of a Heartworm • Female mosquito takes blood from infected host • Mosquito feeds on a dog • The larvae then molts under the skin of the new host (your dog) • Over 50-70 days the larvae migrate into juvenile adults • They move into the blood vessels and turn into sexually active adults • The adult heartworm then breeds and releases immature heartworms in to the blood steam in 6-9 months after infection by mosquito
Pesky Mosquitos Carry human diseases like Malaria and Zika Earliest case of Heartworm Disease was in South America in 1847 This is NOT new and they are NOT leaving! • It only takes ONE infected mosquito bite to transmit heartworms • Over 70 species of mosquitos can transmit the disease • Indoor pets can be bitten as well
