If the mindset is only “the dog needs training”, any training program will fail.
I learned this lesson (among countless others) many years ago with my game changer dog, Lobo. After bouncing from trainer to trainer to help me resolve some significant behavioral issues that developed directly after my divorce, there were 3 massive pieces to the equation each and every trainer missed: 1) the fact that "obedience training" does not resolve "behavioral issues" (every trainer harped on "obedience training" with him; a well-trained dog does not directly translate into a well-behaved dog), 2) the state of mind aspect, and 3) the human ingredient: the part I played in the development and influencing of his behaviors.
