Is this your dog? Found at Moross Rd & Linville St

Found this dog around 615pm tonight on Moross near Linville St across from Henry Ford Hospital. He came right up to me when I pulled over to help him. He’s a very well behaved dog and seems to be well cared for as well. I took him to a local vet to check for a chip, but he doesn’t have one. He drank a whole cup of water when I picked him up so I’m guessing he’s been out for a little while. No collar. Description: black with a small amount of white/grey on his chest, about 15-20 pounds, not neutered, seems like a Shih Tzu mix and has an underbite. Unfortunately, I have a dog of my own and can’t keep him tonight so hoping for some help here. Does anyone recognize him?
