The Bidens’ older German Shepherd, Champ, is 13. He also moved to the Biden’s Delaware home.

The dogs initially moved into the White House in January following Biden’s inauguration. Major is the first shelter rescue dog to live in the White House.

The dogs last month appeared alongside the first lady during the annual Puppy Bowl in a public service announcement encouraging Americans to wear masks amid the ongoing coronavirus pandemic.
