Joe Biden’s Christmas is going to the dogs.

The president-elect and his transition team tweeted a fun video on Thursday of his German shepherds, Champ and Major, celebrating in contrasting styles.

The clip cuts between the older Champ chilling near the Christmas tree to a quiet version of “We Wish You a Merry Christmas” and the rambunctious Major chasing and chewing toys to a rock version of the song.

“No matter how you’re celebrating this year, Champ and Major wish you a Merry Christmas,” Biden wrote. The incoming first lady, Jill Biden, also shared the clip.

Major is a shelter dog and his energy has already made an impact this year. The president-elect fractured his foot while chasing the playful pooch late last month and was prescribed a walking boot.

Biden’s Twitter account also shared a plea to respect Covid-19 safety guidelines for the holidays and a video of his and his wife’s interview with Stephen Colbert in which they discuss their tradition of making fake snow for the season.
