National Heartworm Awareness Month is an opportunity to learn more about this preventable disease and what you can do to protect your furry friend from it. National Heartworm Awareness Month is in April, and it’s the perfect time to educate yourself about heartworms. Heartworm disease is a devastating condition that can affect both dogs and cats, although it is much more common in dogs. The disease is caused by a parasitic worm that invades the heart and lungs, causing serious damage and, potentially, death.

What’s Heartworm Disease Exactly? Is It Curable?

Heartworm disease is a serious condition that can cause heart disease, lung disease, and other main organ damage. It affects primarily dogs, cats, and other mammals. Dirofilaria immitis, a parasitic worm, is responsible for the disease. The mosquito bite spreads the worms. A mild persistent cough, reluctance or decreased appetite, fatigue, and weight loss are all signs of heartworm disease. The disease can lead to heart failure in pets and swollen abdomens due to excessive fluid.

Unfortunately, there is no cure for heartworm disease, but it can be successfully treated if caught early. That is why it’s so important to be aware of the signs of the disease, which can include coughing, lethargy, weight loss, and difficulty breathing.
