Meet Champ Biden.
He is a German shepherd who lives with the Vice President's family.
Joe Biden got Champ for his wife as a post-election present.
Champ and Joe are very close.
But Champ and Joe had a little too much fun together on the weekend.
According to the Associated Press:
Vice President Joe Biden is on the mend from a minor bruise after a little canine roughhousing. Biden was seen on Monday with a dark, penny-sized contusion just below his lower lip. The bruise didn't appear to be a serious injury. The vice president's office says Biden got the bruise from playing with his dog.
