What is the potential outcome of heartworm infection in dogs and cats?

Heartworm infection can lead to severe health consequences for both dogs and cats, making it a critical concern in veterinary care. In dogs, heartworms can be found in the heart and lungs, where they cause significant damage to the cardiovascular and respiratory systems. The presence of these parasites can lead to conditions such as heart failure, severe lung disease, and can ultimately result in death if left untreated.

In cats, while they are seen as atypical hosts compared to dogs, heartworm infection can still be dangerous. Cats can suffer from a condition known as heartworm-associated respiratory disease (HARD), which can cause serious respiratory issues and can also be fatal. The complexity of the disease in both pets underlines the seriousness of heartworm infections, confirming that they are not harmless or merely treatable without consequences.

This reality emphasizes the importance of preventive measures and timely veterinary intervention when a heartworm infection is suspected.
