The German Shepherd, the older of the Biden’s family’s two dogs, was 13 years old.
The President and First Lady, Dr Jill Biden, described Champ as ‘our constant cherished companion’ who was ‘adored by the entire Biden family’ in a heartfelt statement posted on the official POTUS twitter account on Saturday.
‘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 Bidens said.
‘Wherever we were, he wanted to be, and everything was instantly better when he was next to us.’
The Bidens got Champ from a breeder after Mr Biden was elected vice president in 2008.
He became a fixture at the vice president’s home at the Naval Observatory, and more recently at the White House.
The Bidens, who are spending the weekend at their home in Wilmington, Delaware, told how Champ was ‘happiest’ chasing golf balls on the front lawn of the Naval Observatory or ‘racing to catch our grandchildren as they ran around the backyard in Delaware’.
He also enjoyed ‘joining us as a comforting presence in meetings or sunning himself in the White House garden,’ the Bidens revealed.
‘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,’ the statement added.
‘We love our sweet, good boy and will miss him always’.
The Biden’s younger dog, Major, also a German Shepherd, was adopted from the Delaware Humane Society in 2018.
The President and his family were pictured walking their dogs on the White House lawn or taking them for trips to Camp David and Delaware.
Major is said to have been somewhat troublesome in the past, causing the then President-elect to hurt his foot after tripping over the dog while they were playing in November.
He is also said to have undergone training after two biting incidents at the White House.
Days after the second mishap, another stink was caused after one of the Biden’s dogs apparently pooed on the floor of the White House.
