CHANGE ENVIRONMENT, THEN LOCATION,
WHILE ADDING DISTRACTIONS

There is a very valid reason why dogs need to generalise an exercise - although they do not have a detailed and complex memory such as ours, nature has provided them with a very strong sense of location.  This instinctive memory is triggered after the dog has had a good or bad experience and it needs to recall the environment and circumstances in order to survive.

For example, if a dog sees a rabbit (ie prey), when it next passes that particular spot (not only months but even years later) it will be driven to explore the area once again as its instinctive memory recalls that it was obviously a good "hunting spot".   The location and environment trigger the automatic response.  This is also true of threatening or fearful experiences - the dog instinctively feels the need to run away or fight, depending on its ability to escape.
