[UPDATE 5/1/16 9:41pm] News came in that the dog may soon be reunited with its owner. Will post again when more information comes in. Thank you.
According to a Massachusetts Veterinary Referral Hospital post on their facebook page twelve hours ago, a good Samaritan bright him in and they were unable to locate a microchip. This information was sent to LynnHappens 10:17am this morning, so it’s safe to assume the search for his people is still on.
