The arrival of Champ and Major marked the return of pets to the White House after a four-year hiatus under former President Donald Trump, who was the first president since Andrew Johnson in the 1860s not to share the presidential digs with a dog or a cat.
U.S. President Joe Biden and first lady Jill Biden announced Saturday the passing of their "beloved" German Shepherd Champ. The Biden granddaughters chose the name Champ, which was a childhood nickname of the president: His father famously used to encourage him by saying, "Champ, when you get knocked down, get up!"
"Wherever we were, he wanted to be, and everything was instantly better when he was next to us", they said in a statement.
Major has drawn headlines for his bad behaviour in the past.
Mr Biden has had a long association with German Shepherds and has had the breed for pets since he was a child.
The Bidens are spending the weekend at their home in Wilmington, Delaware. The family adopted him eight months later.
The Bidens could occasionally be seen walking their two dogs on the White House South Lawn, and the dogs sometimes would join the president on trips to Camp David or visits home to Delaware. A second biting incident occurred shortly afterwards.
The First Lady described being "obsessed" with getting the dogs settled into life at the White House after the inauguration in January.
It is unclear if the Bidens will get a second dog to keep Major company.
Jill Biden's press secretary, Michael LaRosa, said that Major received some extra training while in DE to help him get adjusted to his new surroundings.
After Joe Biden won the US Presidential Election, a Twitter account dedicated to the first dogs of the US revealed that the two are looking forward to "playing all day and receiving countless treats" at the White House.
