The first dog, Bo Obama, has been a holiday favorite this year, showing up everywhere from the White House Christmas card, to holiday decorations, to the first lady's lap.

Recently, Bo was in tow as Michelle Obama visited the Children’s National Medical Center in Washington, D.C. As the first lady prepared to read "'Twas The Night Before Christmas" to the kids, the large Portuguese water dog leaped onto her lap and made himself the center of attention.

"This is exactly what he does at home," the first lady said on the video. "He tries to beat Malia and Sasha to my lap."

Bo's paw prints can be seen all over this holiday season, including on the back of the White House Christmas card along side the signatures of the president, first lady, Sasha and Malia.

On the front, the card features a painting by Iowa artist Larassa Kabel of Bo playing in the snow. According to People magazine, the painting is based on a photo taken in 2010 of the pup frolicking on the snowy White House Lawn.

According to Colleen Christian Burke, author of “Christmas with the First Ladies: The White House Decorating Tradition from Jacqueline Kennedy to Michelle Obama,” the holiday theme at the White House this year is "joy to all," but it seems as if the real theme is Bo Obama.

“He’s a real celebrity in the White House,” Burke said on CNN’s “Starting Point” Monday.

“This year we have Bo-flakes,” she added. “If you go through, you should find the ornaments that have Bo’s paw prints on them. There are always Bo sculptures and Bo cookies. He is a big, big part of the White House at Christmas.”
