President Biden’s two German shepherds have been moved to the family home in Delaware after one of the animals showed ongoing aggressive behaviour to White House staff, according to a news report.

A report published by CNN on Monday evening said that the dogs, Champ and Major, had been moved after Major had what one person described as a “biting incident” with a member of the White House’s security staff.

White House officials in the East and West Wings did not respond to requests for comment on Monday evening. A person familiar with the dogs’ whereabouts said that Champ and Major had been moved to the family home in Delaware, but added that it was typical for them to stay there when Jill Biden, the First Lady, was travelling. Jill Biden is currently on the West Coast visiting with military families as part of her Joining Forces initiative.

The dogs joined the Bidens at the White House shortly after the Bidens relocated to Washington. Since then, they have been allowed to roam unleashed on the White House grounds and have been given carte blanche to explore the complex. They are often part of the backdrop in Oval Office photos. “They really don’t have any rules, they’re really good dogs,” Jill Biden said.
