A 3-year-old German Shorthair Pointer named Bolt has won a national contest for being the cutest canine. Bolt is trained to detect explosives and works at an airport. The Transportation Security Administration holds an annual "Cutest Canine Contest" with 85 TSA K-9s competing from across the country.

The contest involves TSA employees narrowing down the field to four finalists, and then travelers vote for the top dog on social media. Bolt's win has brought him national attention for his cute appearance.

Further details about Bolt and the contest are available, including how the competition is held and the response to Bolt's win.
