In January, the president and first lady arrived at the White House with their dogsChamp and Major. It marked the first time in four years that a pet had lived at the presidential residence and the veryfirst time a rescue dog called 1600 Pennsylvania Avenuehome. The Bidens adopted Majorfrom the Delaware Humane Association in 2018.
On June 19, the Bidens announced 13-year-old Champ’s death with a touching tribute to the German shepherd.
The Bidens' 2-year-old dog, Major, initially left the White House earlier this year toundergo additional trainingfollowing several “biting incidents” at 1600 Pennsylvania Ave. LaRosa said in a statement that the canine would not be returning to live at the White House, as that is what the first family believes is what is best for the pet.
“After consulting with dog trainers, animal behaviorists, and veterinarians, the First Family has decided to follow the experts' collective recommendation that it would be safest for Major to live in a quieter environment with family friends,” LaRosa said. “This is not in reaction to any new or specific incident, but rather a decision reached after several months of deliberation as a family and discussions with experts.”
This news leaves Commander as the sole pet residing at the White House, but the puppy won’t be alone for long. According to LaRosa, the Bidens plan to welcome a cat, who is currently residing with a foster family, to the White House in January.
