To better qualify the success of learning based theory one must assess the specific relational dynamics in play between dog and owner. Some of these include the personality type of the owner, the relational need of the dog as well as the ideology and methodology intersecting. When training is approached as an intervention than all the pieces fall into place. If you look at the relational model and how I am approaching training I am making sure relational change is happening first prior to using what I define as using relational markers to direct the dog's decision making process.
The majority of training systems have reversed this process. When learning falls apart they are left scratching their heads and wondering what went wrong. The focus needs to be on getting the relationship right before moving to the next step.
