PROVIDENCE, R.I. (AP) — 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.”

Ruby served with the Rhode Island State Police for 11 years and was handled by Corporal Daniel O’Neil, Weaver said.

Part Australian shepherd and part border collie, Ruby was one of the first shelter dogs trained to serve with the Rhode Island State Police. She participated in numerous search-and-rescue missions and made many public appearances during her career.
