No one knows exactly how Blue, a pit bull mix pup, got from Florida to Michigan.

The pooch ended up at the Humane Society of Midland County in central Michigan in March. She was picked up as a stray and staffers were psyched to find she had a microchip. 

They called the phone number registered to the chip. A woman in Florida answered. She told them her dog had been missing for a week. She had no idea how Blue had traveled across the country, but she wanted her back.
