Put the dog to sleep.
Reduction in grade, from Field Grade Officer, (Major) to Junior Officer (Captain). Forfeit all pay and benefits for 90 days.
Not the dog’s fault-you can’t hand a German Shepherd-or any other guard breed dog-to some stupid staffer to walk if that person knows nothing about that breed of dog-the Bidens are obviously stupid pet owners who need a poodle or a Yorkie-not a big dog...
Rehome him where there isn’t so much pedestrian traffic.
