Every village at the Bridge has a school. It is attended by pre-born puppies who need to learn what scientists call “instinct.” A group of the most learned dog professors teaches the pre-borns, led by Dean Apollo. Angels can train for as long as they want, and recently three of Apollo’s most tenured professors resigned. He needed someone he trusted and was an educator on the mortal side. There was only one dog. But, it would break their mother’s heart.
