The internet exploded last week after the nonprofit Massachusetts Vest-A-Dog posted this picture of a 9-week-old German Shepherd trying on a K-9 vest. The picture was dubbed “too cute to handle” by BuzzFeed and “criminally cute” by the Huffington Post. The puppy’s name is Tuco, “named after Tuco Salamanca, a Mexican drug kingpin in the AMC series "Breaking Bad," according to their Facebook page. MA Vest-a-Dog has provided Boston Police Department K-9 unit with 26 vests since 2000. The calendars are available for a $10 donation at www.mavestadog.org. Today, Tuco is six months old and just about fits into his vest.
