Hello! I tried to message you directly but it didn't let me. I'm almost 95% certain I saw this dog as I was heading south on National yesterday morning at around 9:00 AM. I'd just passed the National and Grand intersection and he was out front of the first house on the corner near the entrance to the MSU parking lot. The address of the house in question is 1101 S National. I'm not certain he'd still be around the area but I hope that can narrow his direction of movement down a bit.

I wish I would have stopped but it didn't really strike me as odd until I was already across town. Best of luck finding him!
