Active avoidance can only happen once the dog truly understands the contingency for the punishment. Meaning the dog truly understands the command. If you are having to repeatedly correct then they need to go back to learning the command either via escape or positive reinforcement. If the dog doesn’ truly understand the command you are adminstering a non-contingent punisher and can lead the dog to start to shut down because it does not truly understand what is being asked of it. Like with punishers Skinner states “the mere presentation and rate of the reinforcer is much less important than the contingency of which it is a part.” I invite all to read Skinner, your world will EXPLODE! You can go to his site and read his books for free! Contingencies of Reinforcement is my all-time fave.
