Good boy, Champ. @potus announced Saturday that the Bidens' oldest, beloved dog Champ has died at age 13. The president and first lady remembered the "sweet, good boy" in a post on Instagram. "Our hearts are heavy today as we let you all know that our beloved German Shepherd, Champ, passed away peacefully at home," he wrote. "He was our constant, cherished companion during the last 13 years and was adored by the entire Biden family." The elder of President Joe Biden and first lady Jill Biden's two German shepherds, Champ had been showing signs in recent months of fading energy during public appearances for walks on the White House grounds. "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," Biden added. The aged German shepherd died at home just months after he helped bring canine joy back to the White House. Champ and his younger doggie comrade, the rambunctious, occasionally naughty 3-year-old rescue pup, Major, were the first dogs to take up residence in the White House since Sunny and Bo Obama moved out in 2017. 📸 @gettyimages, @apnews
