A puppy left abandoned in a box in East Boston is now fighting for its life, MSPCA Angell said Tuesday.
The rescue organization said the 6-week-old puppy was found Monday night and is sick with parvovirus, which can be deadly.
As of Tuesday afternoon the dog, who has been named "Tuesday," was stable and is being fed through a tube. MSPCA officials said he isn't out of the woods yet, but his condition hasn't gotten any worse.

"He's got a fighting spirit, so we feel very confident that he's going to be well, but he's not out of the woods yet," said Mike Keiley of MSPCA-Angell.
Authorities are looking to find whoever left Tuesday behind.
All dog owners are reminded that parvovirus is preventable with a vaccine.
