Denise Mankin, DVM, was on duty late one night in a Des Moines, Iowa, emergency veterinary clinic when Yeller, a Labrador Retriever, was rushed in sporting a fresh wound to his back. Yeller had been shot after escaping from his rural home. After stabilizing Yeller with IV fluids, antibiotics, and pain medications, Mankin opened up the dog's abdomen to find blood filling his abdominal cavity. A bullet had perforated Yeller's small intestine in five different locations, and two of the sites were hemorrhaging profusely. Within moments, his blood pressure plummeted. As Mankin worked desperately to tie off the blood supply to his damaged bowel, Yeller went into cardiac arrest. Cardiac drugs restored Yeller's heart beat, and donor blood, having been warmed for transfusion, was pumped into him.
