Why do dogs die from heartworm?

Dogs die from heartworm because of the damage the worms cause to the heart, lungs, and blood vessels. It's not the worms themselves that kill, but the consequences of their presence in the body. Here's a breakdown:

* 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.
