Wow, RexRun 2026… what an incredible day. 🐾❤️

Our biggest turnout yet, and we truly cannot thank you enough for making this year so incredibly special.

To everyone who donated, volunteered, sponsored, brought a vendor booth, participated in the race, cheered from the sidelines, brought their pups, bid on auction items, or simply showed up to support our cause… THANK YOU.

Every single person who showed up helped make a difference for the K9s who serve and protect our communities & schools, and we are so incredibly grateful for every bit of support.

RexRun has grown so much over the years, and seeing our community come together like this is exactly why we keep doing what we do. 🐾

From our entire RexRun & Back the Blue K-9 Force family, thank you for showing up, showing out, and making RexRun 2026 one for the books. We are so incredibly lucky to have this community behind us. ❤️

We hope you know just how much your support means to us. Every donation, every helping hand, every wagging tail, and every person who came out to be part of the day means more than we could ever put into words. We’re so grateful you’re on this journey with us. We’ll be holding onto the memories, the smiles, and all those four-legged faces that make it worth it.

And just like that… we’re already looking forward to the next one. Mark your calendars and come do it all over again with us on August 28, 2027! 🐾❤️

Happy National Dog Day from the goodest boys! 🐾❤️

They work hard to help keep their schools safe…

…but they work even harder to bring joy to the people they serve.

From a quick hello to a much-needed moment of connection, these incredible K9s have a way of making every interaction a little brighter.

Happy National Dog Day to our SRO & Patrol K9 heroes — and all the good they do every single day. 🐾❤️
