What to Expect
RexRun for PAWSitivity opens at 7:00 a.m., so bring your pup and sniff out the Vendor Marketplace early! The trail run starts at 7:50 a.m. after the National Anthem, followed by the trail walk at 8:00 a.m. Once your cross the finish line, refuel with a pancake breakfast from Flippin’ Flapjacks (8:30-10:30), then cheer on the kids during the Kids Fun Run at 8:45 a.m.
The fun doesn’t stop there! All day long, enjoy exciting therapy and police dog demonstrations, and be sure to strut your stuff in our dog costume contest-the winning pup goes home with a prize-packed basket. Our silent and live auctions are packed with wag-worthy finds you won’t want to miss.
Our Kids Zone is bursting with fun with inflatables, games, an obstacle course, face painting, and yummy snow cones. Be sure to wander through the Vendor Marketplace for giveaways and expert tips from the pet pros!
Well-behaved dogs are welcome inside on a 6-ft, non-retractable leash—let the tail-wagging fun begin!

About Us
RexRun For PAWSitivity was inspired by a conversation with the Sergeant of the School Resource Officer (SRO) K-9 Unit and a shared goal to support therapy dogs that help students in crisis and those with special needs.
SRO K-9s are highly trained to calm students and adults during stressful situations. In addition to their work in schools, many serve in specialized roles, including explosive detection, locating electronic storage devices that may contain child sexual abuse material (CSAM), and tracking missing persons.
These incredible K-9s provide comfort when it’s needed most while helping keep our schools and communities safe.
