Happy Birthday, Bo! On top of being one lucky dog, we're pretty sure that Bo is the first pet to ever get a birthday shout out in a Nobel Prize press conference. In honor of the White House pup's first birthday, HuffPost Green thought we'd take a look back at Bo's first six months with the Obamas. Check out these photos, and vote on your favorite pic of Bo.
Also, feel free to leave your birthday wishes for Bo in the comments.
