And a 13-year-old Massachusetts girl is being thanked.
Eighth-grader Anna Barowsky struggled for months to raise the $750 to buy the vest.
MBTA Transit Police Chief Paul MacMillan says Anna made dog-shaped biscuits, doggie earrings out of clay, homemade whole wheat dog biscuits and even had a lemonade stand.
Anna is to get a "Certificate of Appreciation" at a special ceremony this morning at transit police headquarters in Boston.
