Much better is to keep the dog away from ANYTHING that triggers him for a long time, at least a few weeks if not months and in the meantime train some commands that get the dog looking at you instead, focussing on you, so you have a powerful interruptor that can be used later. This is the key to solving it - a powerful interruptor that is stronger than the initial impulse and the feelgood fix. If you work hard away from the triggers to achieve a strong interruptor, then you can start slowly re-introducing the stimulus, from afar at first, slowly working towards what you want and need. I found other ways of getting his attention and we have just gone back out there into the big wide world and things are a LOT better, not perfect yet but I do have a great interruptor. I also read up LOTS on dog body language so I could accurately spot the very moment my dog was going into stress mode or chase mode, and pre-empt it. Keeping him away from them was a good thing, it weakened his addiction.
