Sure sounds like a pet the owner would like to get back. I'm assuming there's something wrong with that phone number situation- was there an area code, did you dial the right number? Hard to believe the dog has the wrong collar or tag on it.

I'd hang onto the dog and check craigslist for starters. You could also have it scanned to see if there's a chip. Call the local pounds and see if they have someone looking for their dog and give them your information. You could post up flyers, maybe leaving out the dog's name and phone number so you have something a caller could verify.
