U.S. President Joe Biden's dogs are back in the White House after being sent to Delaware when Major, the younger German shepherd, allegedly bit a Secret Service agent, Inquirer reported Thursday.

"Champ and Major are here at the White House," White House Press Secretary Jen Psaki told reporters in a briefing Wednesday.

Major, the 3-year-old rescue dog, also underwent training while in Delaware, CNN said. Major is the first shelter dog to live in the White House.

Psaki said earlier this month that the dogs were slowly adjusting to their new surroundings at the White House when the biting incident happened.

After a reported incident involving a White House security staff member, Biden told ABC News that Major was just being protective.

Biden defended Major's actions earlier this month, saying it did not "bite someone and penetrate the skin."

The president said the dogs' visit home to Delaware was a pre-planned trip and had nothing to do with the incident.

Twelve-year-old Champ joined the Biden family in 2008. They adopted Major in 2019 after fostering him from a litter of six other German shepherd puppies.

First lady Jill Biden has said training Champ and Major for their new life at the White House has been a priority since they moved in after Biden's Jan. 20 inauguration.

The first lady has also hinted they may get a cat.
