Over the Hill

Behind the hedges, the path goes over a hill. It climbs the hill in steps, like stairs, and on the other side, it goes down in steps again, all the way to the goal.

Both halves of the path are made of steps that repeat. You know the way up from the Stairs exercise. The way down is harder: there, the steps go in another direction.

A tip: a loop does every pass the same way, so each pass starts with the dog facing the way the previous pass left it. Which way is the dog facing when it reaches the top? And which way should it face at the start of each step down?
