Champ, Joe Biden’s beloved pet dog, died in peace, and the president has paid tribute to the friend who had been there for his family “in our most joyful moments and in our most grief-stricken days.”

The Bidens revealed Saturday June 18, that the German Shepherd, who was 13 years old, died at the White House.

The president said he will miss the family dog, who has been with them since he was elected vice president in 2008.

“Our family lost our loving companion Champ today. I will miss him,” he twitted.

Mrs Biden wrote on Twitter: “RIP to our sweet, good boy, Champ. We will miss you always.”

They said: “Our hearts are heavy as we let you all know that our beloved German shepherd, Champ, passed away peacefully at home.

“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.

“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.

The Bidens got Champ as a puppy in 2008, just after Joe was elected as Barack Obama’s Vice President.

Champ’s name was chosen by Biden’s grandchildren as a touching tribute to one of their grandfather’s well-known remarks.

“Any time you get knocked down, champ, get up!” Biden remembered what his father used to say.

When the Bidens moved into the White House in January, Champ and the couple’s other dog, Major, joined them.

Major, a three-year-old German shepherd, was the first rescue dog to ever live in the White House.

Major has had a difficult time adjusting to life at the White House, and after biting two government employees, he was temporarily sent away for more training at Biden family home in Wilmington, Delaware.

In recent months, the two dogs have gained popularity on social media, with their own Instagram account @first_dogs_usa and Twitter account @TheOvalPawffice recording their escapades.

@first_dogs_usa shared a photo of Biden and Champ together on Friday.
