The Signs and Symptoms of Heartworm Disease

Heartworm disease is a serious condition caused by parasitic worms that live in the heart, lungs, and blood vessels of affected animals. It is spread by mosquitoes and can affect dogs, cats, and other mammals. At Lakewood Pet Vet, your veterinarian in Lakewood, CA, we see the impact this disease can have when it is not detected early. Like a clog in a critical pipeline, heartworms interfere with the body’s normal flow, putting strain on vital organs. If you are looking for a heartworm test, we are here to help.

Early Signs to Watch for

In the beginning, symptoms can be subtle or even absent. Mild coughing, occasional fatigue, or a slight decrease in activity may be the only clues. These signs are easy to overlook, especially in active pets. Regular checkups and testing are important because early detection increases the chances of successful treatment.

Progressive Symptoms

As the infection advances, the signs become more noticeable. Persistent coughing, difficulty breathing, weight loss, and reduced appetite can appear. Some pets may tire quickly after moderate activity. The worms grow and multiply over time, creating more blockage in blood flow, much like sediment building up in a water line until it affects performance.

Severe Stage Indicators

In advanced cases, symptoms may include a swollen abdomen from fluid buildup, collapse, or sudden difficulty walking. These signs indicate significant damage to the heart and lungs and require immediate veterinary attention. At this stage, the disease can be life-threatening.

Heartworm in Cats

Cats are less likely than dogs to develop heavy worm loads, but even a small number of heartworms can cause serious problems. Symptoms in cats may include coughing, vomiting, or sudden collapse. Sometimes the first sign is sudden death, which is why prevention is critical.

Why Testing and Prevention Matter

Because the early stages of heartworm disease are often silent, annual testing is essential. Preventive medication, given monthly, can stop the disease before it starts. Prevention is far safer and less costly than treatment, which can be lengthy and risky.
