President Joe Biden‘s dog, Commander, had at least two dozen biting incidents with U.S. Secret Service agents before being moved out of the White House, prompting the Secret Service to adjust operating protocols at not only the White House but also Camp David and Biden’s Delaware homes, according to internal documents.

The documents themselves were first obtained by John Greenewald of the government transparency group The Black Vault through a Freedom of Information Act request. The documents detail Secret Service agents’ efforts to work around the German shepherd and catalog each individual biting incident.
