There was public support when the president and First Lady Dr. Jill Biden brought Champ and Major with them upon moving into the White House — it marked the first time in four years that a pet had lived there, and Major is thefirst rescue dog to live at 1600 Pennsylvania Avenue.

CNN reported that Major is the rowdier of the dogs and that he sometimes exhibits aggressive behavior like barking, jumping and “charging” at staff. Champ at 14 is reportedly more mellow.

Recounting the incidentto CNN at the time, Biden explained that he had just gotten out of the shower when Major dropped a ball in front of him.

“And I’m walking through this little alleyway to get to the bedroom. And I grabbed the ball … and he ran,” Biden said. “And I’m joking, running after him and grab his tail. And what happened was that he slid on a throw rug. And I tripped on the rug he slid on. That’s what happened. Oh man, not a very exciting story.”
