The Petagon 

The headquarters building of the United States Animal Companions Department of Defense, located alongside The Pentagon in Arlington County, Virginia.

We took our furchildren Fifi and Foofoo, to visit The Petagon so they could see this very hallowed of historic buildings and tell their puppies about it one day.
