A Rhode Island dog whose inspiring story of going from shelter dog to lifesaving police K-9 became the subject of a recent Netflix movie has been euthanized.

State Police said Sunday K-9 Ruby was put down Friday following a “sudden, acute, and untreatable illness.” She was 11 years old.

Col. Darnell Weaver, superintendent of the state police, expressed gratitude for K-9 Ruby’s years of service.

“K-9 Ruby dedicated her life to serve the citizens of Rhode Island and make a positive impact on every person she ever interacted with,” he said in a statement. “She became a symbol of hope for all shelter dogs, showing the world what a shelter dog can do when just given love and the chance to shine.”
