When to reward?

A wonderful blog post by Dr. Patricia McConnell focused my thoughts on when to reward our dogs.  Obviously, in my opinion for a novice nosework dog you want to reward after each successful find or when you help the dog find the odor when they have tried their best.  But what about an advanced dog obviously if they find one hide that’s a “good dog” but the room has two more hides left to go so does the reward go at the end? Please share your thoughts.
