I always enjoy this thread!
Just finished a trial w/ my club and the dogs lost nothing on their bark and holds.
Yet, I almost ALWAYS initiate the work with some type of helper correction!! Exceptions to this are really powerful dogs that I'm not willing to go to war with.
I especially do this with law enforcement dogs where I spend more time utlizing helper corrections and return to them when we proceed to varying environments/ scenarios.
Ivans approach works well, unless the dogs really bite (not protest a little and grab at the helper but bite). Sometimes this can still be accomplished by the decoy pulling the dog into the arm with a leash attached to the collar while the handler approaches and admonishes the dog for its mistake.
But why helper corrections? What about the anthropomorhic answer that if my dog is met with aggression he should bite?
First, what we teach is move and you'll be bitten. Simple appraoch, simple to understand. It includes allowances for minor movement (or in the case of police dogs, natural movement to include things like protective movemetns like raising their hands to cover their face etc.).
Second, if I want the dog to look at the decoy from the outset as a potential combatant, not simply a motor behind the sleeve, I have to remove from the dogs the desire to make prey on the equipment hanging on my arm. Helper corrections do this.
Do they continue ad infinitum? NO! My dog was started with helper corrections and so has virtually EVERY dog in my club and that I have placed on the street, and once past the initial helper corrections, they will and do, fight bad guys who batter them. Do they tolerate helper corrections, sure, it is a training tool I use and keep in my basket. Does it cause the dog to not fight bad guys with sticks? No, in fact, watch a stick trained dog around someone with a stick, it is, in fact very in drive and focused.
Where do I go from the initial helper corrections? I often go to using the e-collar, w/ intermittant, frequent low level stimulations while barking. Occasionally it is used continous mode for some really difficult dogs to stop their motion into the blind with an immidiate return to momentary stimulations for the barking.
Rule of thumb.....frequent short corrections create action, a single strong correction ceases action. Barking is action so we use short repeated corrections.
The dog is also taught to be uninhibited about being hit by a stick while engaged with a helper and that displays of fighting behavior (bigger stronger grips, biting deeper, and draging down the helper for sport, any fighting that is forward such as head shaking, leg wrapping, as well as the acceptable sport behaviors for the service dogs).
Now, for those still unconvinced about the decoy correcting the dog, especially those who have the mistaken idea that they want their dog to be powerful under the stick, I will direct you to K. Mosts book. I will also state that the idea that a dog should be thundered by a guy with a stick, though pervasive in all working dog circles (and a superb test of character for breeding stock) is possible way off the mark. Dogs are simply flesh and blood, and really not great weapons. Wouldn't we be better served if our dogs meant for many types of service were taught to let go of the bad guy that swings at them and move to the opposite side and reangage? Quite honestly, one of the reasons we don't do this is that we don't want to have to explain why the bad guy got bit multiple times. The other is that sport has forced the idea that a tough dog hangs on regardless of what happens to him, I guess even if that is being beaten to death (and thereby uselessness in the event), when maybe training should take a different angle on this in regards to some service dogs.
For those in sport, whatever produces the greatest intensity at the blind and often that can be the stick given the right decoy, right handler, and proper balance to the work.
Just some food for thought.
