Just saw a large black pitbull roaming up Chestnut (from Mozart in the direction of Stony Brook) about half an hour ago (6:15ish). I called Animal Control who said they'd "see if they could send someone out," and MSPCA and ARL were closed/not answering phones when I called.
Keep an eye out so we can help get that guy/gal home and also make sure our neighbors are safe!
He didn't seem aggressive - didn't hear any growling/barking and I saw him walk past a couple people with no fuss. When I was closer to him, he was definitely on alert in a way that may have been curiosity or nervousness.
If you see him/are able to call Animal Control with an updated location of the dog, the # is: 617-635-5348.
