He's older but he looks good. I'd bring him to the vet like wick said. Check his ears for a tattoo. That may help for finding an owner.
If he still has his nuts I bet he slipped his collar and got out. I'd try to find his owner.
I lost my chocolate lab that way. Still kinda hurts inside that I lost my buddy.
