Heartworm Life Cycle |
|
|
|
The adult heartworms live in the heart and major arteries of the lungs. The worms produce microfilariae (baby heartworm larvae), which circulate through the dog's bloodstream. |
| Mosquitoes bite a dog infected with heart worms picking up the microfilariae that are circulating in the infected dog’s blood stream. The microfilariae undergo several changes, or molts, in the mosquito’s system. This takes several weeks. | ||
| The infected mosquito bites another dog and transmits the larvae into the dog’s bloodstream. | ||
| Over the next 4-6 months, the heartworm larvae develop and migrate to the dog’s heart and lungs. |
What are the clinical signs of heartworm disease?Heartworms live in the heart and in the major arteries of the lungs. They can grow up to 10-14 inches in length and cause permanent heart and lung damage and even death. Clinical signs can include:► Coughing ► Difficulty breathing ► Sluggishness ► Weight loss ► Sudden death Can heartworms be treated?If diagnosed early, most dogs can usually be success-fully treated with a recently developed drug called Immiticide. Treatment is expensive, and some dogs may have permanent damage done to the heart and lungs. Should my dog be tested?Puppies can start on a preventive without testing. Dogs over six months old could possibly have adult heartworms. They should be blood tested prior to starting the preventive to avoid serious reactions.
