Which of the following is a typical consequence of untreated heartworm disease?

• A. Weight gain
• B. Coughing and lethargy
• C. Increased appetite
• D. Shiny coat

Answer: (B)

Untreated heartworm disease typically leads to serious health complications, particularly affecting the respiratory and cardiovascular systems of the affected animal. Coughing and lethargy are common symptoms because heartworms reside in the pulmonary arteries and can cause inflammation and damage to the lung tissue. This results in difficulty breathing and a persistent cough, reflecting respiratory distress. Additionally, as the disease progresses, the heart's ability to pump blood can decline, leading to overall fatigue and a lack of energy, which manifests as lethargy. In contrast, weight gain, increased appetite, and a shiny coat are not associated with heartworm disease; in fact, pets may lose weight or have a reduced appetite due to the severity of their health issues. Therefore, coughing and lethargy are significant indicators of the presence and impact of untreated heartworm disease.
