Which clinical sign is most suggestive of left-sided congestive heart failure in a dog?
Correct answer: A. Pulmonary edema with coughing
- A. Pulmonary edema with coughing
- B. Marked abdominal distension only
- C. Persistent polyuria without dyspnea
- D. Isolated hindlimb lameness
Explanation
Left-sided heart failure increases pulmonary venous pressure and may cause pulmonary edema, coughing, and respiratory distress. Right-sided failure more commonly produces systemic venous congestion, including ascites. Polyuria and lameness are not defining signs of left-sided failure.
