* Heartworm larvae mature into adult worms that live in the heart and pulmonary arteries. These worms can block blood flow, leading to:
* Heart failure: The heart struggles to pump blood effectively due to the blockage and inflammation caused by the worms.
* Lung damage: The blocked pulmonary arteries cause pressure build-up, leading to damage to the lungs and difficulty breathing.
* Blood clots: The worms can trigger the formation of blood clots, which can travel to the lungs and cause further damage.
* The body's immune response to the worms can also cause problems. The immune system tries to fight off the worms, but this can lead to:
* Inflammation: The body's inflammatory response can damage the heart, lungs, and blood vessels.
* Secondary infections: The weakened immune system can make dogs more susceptible to other infections.
Ultimately, heartworm disease is a progressive and debilitating condition that can lead to death if left untreated. However, with prompt diagnosis and treatment, many dogs can recover.
Here are some key points to remember:
* Prevention is the best way to protect your dog from heartworm disease. This involves administering monthly heartworm medication.
* Early diagnosis is crucial for effective treatment. If your dog shows any signs of heartworm disease, see your veterinarian immediately.
* Treatment is complex and can be expensive. It involves a series of injections and medications.
* Recovery can be slow and requires careful monitoring.
If you have any concerns about heartworm disease, please contact your veterinarian for more information.
