Lost small brown dog named Max with a blue collar near the park off Main Street in Central Michigan.

I lost my small brown dog while walking him near the park just off Main Street in Central Michigan. His name is Max, and he has a blue collar with a tag that has my phone number. He's friendly but can be timid around strangers. I last saw him around 5 PM on Tuesday, and I'm really worried about him. If you see him, please let me know!
