U.S. President Joe Biden and First Lady Jill Biden mourned their German Shepherd dog "Champ" today, Saturday. The Biden family described their dog as their "beloved constant companion" for 13 years. In a statement, Biden said, "He was with us in our most joyous moments and on our saddest days, and he was sensitive to all our unspoken feelings and emotions. We love our beautiful, kind dog and will miss him always." "Champ" was one of two dogs of the same breed living in the White House with the president and his wife.
