Finally, a nurse named Karen crouched slowly, extending her arms toward the girl. The dog let out a low, guarded growl—not from aggression, but from fear. His body was tense, protective, unwilling to let her go.

Then Karen whispered gently, “It’s okay. I’m here to help.” At that, the shepherd shifted just enough for her to lift the girl into her arms. The child was frighteningly light, her skin clammy and cold.

“Pediatric emergency!” Karen shouted as she sprinted toward the trauma bay. Doctors snapped back into motion, stretchers rolled into place, alarms blared. Yet no one could shake the image of the dog carrying her through the doors.
