Found medium-sized friendly brown dog with collar but no tags in backyard near park.

We found a friendly medium-sized brown dog in our backyard yesterday, running around and looking lost. It seemed quite scared but approached us without hesitation. The dog has a collar with no tags, and it's well-groomed. We suspect it might belong to someone in the Southwest KS area, as we live near the park. If you recognize this pup, please reach out!
