A Lexington family is desperately looking for its black lab mix named Bear.
Bear, who was adopted earlier this week, ran out an open door and has been missing since. He doesn't know the area and his family is worried about him.
There were four sightings on Wednesday near his home near the golf course at the end of Cedar Street.
If you see him, please do not chase him as he will run. He's scared, timid and harmless. Please call 781-608-3807 if you see him.
