The fastest, easiest, most effective approach is to recreate the undesired situation in a controlled setting, and correctly use sound distractions with praise to erase the misbehavior. Dogs can learn or unlearn almost anything in four properly conducted repetitions.
Taken to it’s extreme, these four repetitions should be performed in four different places, or with different people, dogs, or whatever the “props” involved may be. Understanding how dogs think, learn, and process information is a stretch of the imagination for most of us. It is obvious that they know more about psychology than we do.
They think, have a sense of humor, communicate, tease, lie, steal, etc. just like any one else. But, they don’t think human. Dogs are limited to thinking like dogs. It’s your responsibility to think things out from their perspective and try to use good judgement.
Be consistent. Dogs get confused if you’re not consistent. Now that you are getting familiar with teaching a command through conditioned reflex, you can use similar techniques to stop or break any behavior whatsoever.
Using a set of cans, or any other source of sound, so long as it is brief, and so long as it can be presented from different directions on each consecutive instance, are all that you need to do to break any behavior. Simply create the sound, and follow through with praise! It’s that simple. Any behavior can be stopped or broken, simply by creating a sound, and praising immediately. The secret is, to allow the undesired behavior to begin again, and simply present the sound from another direction, and follow through with praise. Of course you have to understand how your dog thinks and learns in order to successfully achieve this.
What you do is create the sound every time bad behavior starts and follow that with praise. You will have to so this several times in order to change his conditioning. It takes persistence.
Of course, you may continue correcting your dog forever, as most trainers do. We do not understand why a trained dog needs correction. Seems that if he were trained, that would be the end of it. That would imply that if a trained dog makes a mistake, that this mistake is probably not an accident, but rather, a challenge to your authority.
You will soon come to enjoy this process because it really works well and you can take satisfaction from knowing how to change behavior. Do bear in mind that this is changing existing behavior, not teaching new behavior.
