I can't imagine why someone will suggest weeks of ignoring the dogs. How they suppose to understand what you DO want from them? They don't understand time as it is abstract, past and future does not exist for them. That is sweetest part about dogs, they live in the moment- 5 minutes of timeout is an eternity for them. Usually 2 minutes is a max for dog to dissociate behaviors so they don't create patterns. My timeouts last long enough for me to come up with new idea how to proceed.
Controlling reinforcement is very valuable tool but not by weeks of ignoring the dog. Since I train my dogs that collar grab is good thing to happen at some point all I need is to hold the collar to prevent them from going to sniff or redirecting them if they too involved for the moment. Since they do not get upset for collar touch it is enough of timeout for them to reset the picture. And then again I will evaluate why did I have to use it- was I training too long, do I need more often breaks, did not have good level of arousal, my reinforcement rate low, etc.
Punishments, even mild ones should not be given lightly.
John Rogerson mentions that punishment/ correction is a bar of slippery soap that you are trying to reshape in the shower by standing with your foot on it- soap MIGHT reshape but more likely will shoot from under your foot in any direction...
Well said.
