RexRun For PAWSitivity 2026 Trail Run/Walk

RexRun for PAWSitivity 2026 opens at 7:00 am so you can visit with the doggies and get an early peek in the Vendor Marketplace! Our family 5K run/walk event kicks off at 7:50am with the singing of our National Anthem. The 5K trail run begins at 8am and is followed at 8:10am with the 5K walk (dogs are welcome!) and the kid's run at 8:45am. Afterwards, treat yourself to a tasty pancake breakfast (free for all registered participants) at the Flippin' Flapjacks food truck! Throughout the day, we will feature therapy and patrol dog training demonstrations. Be sure to catch our colorful dog costume contest (complete with a prize basket brimming with canine fun) and participate in both our silent and live auctions that are always too good to miss!

The Kids Zone will feature inflatable activities, a selection of lawn games, an obstacle course and balloon catapult for family fun. Meanwhile, children can enjoy face painting, and, naturally, snow cones! Don't forget to explore the Vendor Marketplace for event giveaways and to consult with specialists about your pet needs. Dogs are permitted in the inside event area provided they are well-behaved and on a 6-foot leash.

Who is Rex and why he is so important?

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 2025 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 2025 go to Back the Blue K-9 Force.
