(in the US) even if not posted, the generally understood(even if unwritten) rule applies in most things - slower traffic (i.e.: pedestrians) keep right - faster traffic (i.e.: bikes) pass on the left.
Pedestrians should walk facing oncoming traffic, whichever side of the road that may be.

When I was training my dog, I was always told that you should train them to walk on the right side of the sidewalk. Even then, I always see owners walking their dog on the left side of the sidewalk.

I hope this is what you meant, otherwise, I'm sorry I don't have that answer.
In the UK the sidewalk is commonly referred to as the pavement.
