President Biden’s four-legged friends are back at 1600 Pennsylvania Ave. after completing training for a biting incident with White House staff.

News broke Tuesday that the German Shepherds, Major and Champ, finished up training in Delaware and were reunited with their owners. As we reported, BOTH dogs were sent packing after Major bit a Biden staffer.

President Biden recently revealed the incident with Major was just an example of the pooch being protective, and the bite didn’t break the skin … yet it was still enough for the extra training.

We had one of the dog’s former trainers on ” Live” who told us a move to The White House translates a lot of sudden changes for the pups, including a totally new environment. Apparently, both Major and Champ are quick learners, because the new training lasted only two weeks.

Unclear what’ll happen if the misbehaving returns … but at least for now, Major and Champ are out of the dog house.
