• Vascular Pathophysiology of GDV in Canines:
• When the stomach rotates clockwise on its mesenteric axis (volvulus, typically $180^\circ - 360^\circ$):
• The spleen is displaced and the short gastric arteries and left gastroepiploic vessels are stretched, avulsed, or thrombosed.
• Because these vessels supply the Greater curvature of the stomach, this anatomical region suffers severe hypoperfusion and venous congestion, making the greater curvature the most prone to ischemic necrosis and perforation.
• nalysis:
• (Greater curvature): Correct.

Correct option: (3) Greater curvature
