Part 3 - Following

Every turn when the dog is tame and the dog is somewhere (this is the dog moving rule):

let the target be the location;

let kennel be the location of the dog; [1]

if the kennel is the target:

make no decision;

if (the kennel is the Upstairs corridor and the target is the Hotel lobby) or (the kennel is the Hotel lobby and the target is the Upstairs corridor): [2]

make no decision;

let the way be the best route from the kennel to the location, using doors;

if the way is not nothing and (the door way from the kennel is nothing or the door way from the kennel is open):

try the dog going the way.

Last report going when the tame dog is in the location:

say "The dog wags his tail, glad to see [us]."
