Champ had been part of the Biden family for the last 13 years. He was one of two German Sheppards living at the White House. The other one is named Major.
Champ also lived in Washington when Joe was vice-president during Barack Obama's term in office.
The White House released an official statement on behalf of the Bidens. The couple said that they "will miss him always".
"Our hearts are heavy today as we let you all know that our beloved German Shepherd, Champ, passed away peacefully at home", the statement said.
"He was our constant, cherished companion during the last 13 years and was adored by the entire Biden family. Even as Champ’s strength waned in his last months, when we came into a room, he would immediately pull himself up, his tail always wagging, and nuzzle us for an ear scratch or a belly rub", the statement continued.
"Wherever we were, he wanted to be, and everything was instantly better when he was next to us. He loved nothing more than curling up at our feet in front of a fire at the end of the day, joining us as a comforting presence in meetings, or sunning himself in the White House garden".
"In his younger days, he was happiest chasing golf balls on the front lawn of the Naval Observatory or racing to catch our grandchildren as they ran around our backyard in Delaware".
"In our most joyful moments and in our most grief-stricken days, he was there with us, sensitive to our every unspoken feeling and emotion. We love our sweet, good boy and will miss him always".
