Left-sided heart disease in dogs is commonly associated with which pulmonary finding?

• A. Lung congestion
• B. Ascites
• C. Nerve Degeneration
• D. Osteoporosis

Answer: (A)

When the left side of the heart isn’t pumping effectively, pressure backs up into the pulmonary circulation. This raises hydrostatic pressure in the pulmonary capillaries, causing fluid to leak into the lung interstitium and, as it progresses, into the alveoli. The result is pulmonary edema or lung congestion, which is the typical pulmonary finding in left-sided heart disease in dogs. Clinically you may see coughing and difficulty breathing, and radiographs often show interstitial to alveolar edema centered around the lung bases or perihilar regions. Ascites speaks more to right-sided heart failure with systemic venous congestion, while nerve degeneration and osteoporosis are unrelated to this cardiac issue.
