In a statement on Tuesday, the Secret Service said the attack occurred on Monday night.

During his 11 years at the White House and the home of the Biden family, the dog has bitten 11 guards.

In the past, the White House press secretary has blamed the attacks on the stress of living in the White House.

“We all know that the White House complex is unique and stressful. That is something you can all appreciate,” she said in July.

As unique as it is, it is stressful for all of us. So you can imagine what it is like for family pets, in general.”

The younger of the Biden family’s two German Shepherds is Commander. Another incident of biting occurred at the Delaware home of the president and first lady.

According to Secret Service spokesman Anthony Guglielmi, a Secret Service Uniformed Division police officer was bitten by a First Family pet yesterday evening around 8 p.m.

Later, he told CNN that the injured officer spoke with Secret Service Director Kimberly Cheatle on Tuesday and is doing well.

White House officials said they were attempting new leash and training techniques on Commander following a rash of attacks on personnel. He has since been moved out of the White House and is now staying with Biden family friends.

As a puppy, Commander arrived at the White House in 2021. James Biden gave him to Mr Biden as a gift.

Willow is also a cat owned by the First Family.
