The soon-to-be first pet is being honored with a virtual "indoguration" celebration on Jan. 17, courtesy of the Delaware Humane Association — the shelter President-elect Joe Biden got him from.

That means inauguration day is as big a deal for Major as it is for his owners, Joe and Jill: Along with older brother Champ, Major will be ascending to the highest canine office in the land, First Dog. To celebrate, the shelter from which the Bidens adopted Major, the Delaware Humane Association, will be holding their own livestreamed inauguration event on January 17: Major Biden's Indoguration Party.

President-elect Joe Biden's two German shepherds, Champ and Major, showed off their opposite personalities in a sweet video montage that shows the two canines getting into the holiday spirit."No matter how you’re celebrating this year, Champ and Major wish you a Merry Christmas," Biden wrote alongside the festive video.

President-elect Joe Biden and his wife, Jill Biden, are preparing to move into the White House in January, and their dogs, Major and Champ, will join them, marking a significant first for animal lovers.
