About K-9 Rex

The star of our event is K-9 Rex, a four-year-old black Labrador therapy dog. He and his fellow K-9s with their handlers go to local schools to primarily offer comfort to students with special needs, many who are in crisis and are dealing with stress, anxiety and depression. RexRun for PAWSitivity 2026 is presented by Back The Blue K-9 Force, a volunteer-run nonprofit organization. It is dedicated to providing funding for safety and training equipment, health care needs as well as expanding the team of K-9s to meet the needs of these communities. 100% of all net profits from RexRun for PAWSitivity 2026 go to Back The Blue K-9 Force.
