Just like I don't need a car. I can get around fine on a bicycle.
If one train protection dogs or says they do, that automatically means you must be doing advanced obedience. Maybe not competition level but certainly not pet level. If this is so, and especially because one is dealing with very hard animals, why would you NOT use a tool that clearly demonstrates better results. Scientifically proven.
My training director says it best. You get better or you just get left behind.
I train pet owners to use the collar. Granted not in the say way.
Let's put it this way. You crank on a dog long enough with direct physical contact and without teaching dog that it is his behaviour and not the owner who is causing the correction, 100% of time, he will crawl up the line. Now don't get me wrong, a mistimed e correction will do the same but much less degree with good timing. Good timing is prerequisite for leash or e collar training. As stated in study leash corrections were MORE stressful .
Food for thought. Why do you think the level of performance especially in OB has improved SO much? Simply put the dogs look happier and more precise since the use of advanced e collar work.
