 Extract: //Recalling the yahtzee search, we can see how the box was a **predominate object in a scent pool**. The yahtzee box meant nothing, it was simply something that stood out and the dogs picked it to show us. We insist during training that they show us something specific, so the dogs have learned that we expect them to show us a thing/​location. When the dogs can easily find the scent source they will show us, but when they have a scent pool or are unable to get to or find the source, they show us something that probably has scent on it but is not necessarily the scent source. A **buried body** sometimes gives off less scent where it lies than does the scent pool that has formed, and **the dog will show us the scent pool**. Extract: //Recalling the yahtzee search, we can see how the box was a **predominate object in a scent pool**.

 We tend to think that every thing our dogs do is significant. We feel we have trained them to show us where the scent source is. In training this is possible, but on a real search we may not know the correct answer. What we have done is train them to show us something so they can please their handler and be rewarded. They have learned to make us happy by showing us something within the pool - anything. Try setting up a training problem (buildings work very well) **where the scent source is up high or not accessible to the dog**, and watch several dogs work. Can be a wonderful handler learning experience.//​ We tend to think that every thing our dogs do is significant. We feel we have trained them to show us where the scent source is.

 +Such problems can mostly be circumvent by isolating the objects in question from the surroundings.
