Which symptom is most characteristic of GDV when the stomach is distended?

• A. Lethargy only
• B. Abdominal distention
• C. Diarrhea
• D. Excessive barking

Answer: (B)

Abdominal distension stands out as the most characteristic sign when the stomach is distended. In GDV, the stomach fills rapidly with gas and gas buildup or twists on its axis, causing the belly to become visibly enlarged and firm. This distension is the key external clue clinicians look for and often the first noticeable symptom.

Other signs can occur, like restlessness, nonproductive retching, drooling, and rapid breathing, but they’re less specific. Lethargy alone and diarrhea aren’t typical hallmarks of GDV, and excessive barking isn’t related to this condition. The important takeaway is that a visibly distended abdomen is the hallmark feature signaling a potential GDV, which requires urgent veterinary care.
