I was wondering if anyone has any experience with this collar? I have a chance to buy one from someone in Denver for nearly half the price and I was wondering how well it works? I do not like most of Ceaser's techniques, but this collar seems like it would work well.

The reason is that Qenna is going to the Women's prison for board and train to finish her Service Dog training. Right now she has graduated from the prong collar to the choke. Obviously they cannot allow the use of metal collars in the prison so I thought this collar might be a good alternative. I have tried the gentle leader with her, but she will not accept the use of it whatsoever. I've also tried that no pull harness that attaches to the front and it does absolutely nothing for us.

Thanks in advance!

So I ended up ordering the Illusion collar this weekend. It should be here in a couple of weeks and I'll let you all know how well (or bad) it works

AS a professional trainer I have never heard of *graduating* from a prong to a choke collar.

If the prong collar was used correctly (AS DESIGNED) as a "TOOL" in concert with using the/a correction based *method* of conditioning (undesired) behavior ...the use of a choke collar would be considered a continum of the correction curve and in addition possibly more damaging to the dogs trachea and thus a step more to the negative side I would think.

The illusion collar is just Cesars rendition of a "nicer" more eye friendly for some ....looking correction based choke collar/tool that has the advantage of keeping the collar high up on the dogs neck where corrections are more effective and damage to the trachea/throat tissue is minimized. The concept however is the same when considering correction based conditioning in that a true correction results in delivering a stimulus at or above the threshold to eliminate unwanted or undesired behavior so that it does NOT repeat. In this case a aversive choking or restriction of the neck.
Again as I pointed out in more detail in the training article forum reply on leash training.... "Repeated" use of aversive based stimulis (popping or pulling the leash) or in the case of a choke collar (CHOKING/RESTRICTION ON THE NECK/TRACHEA) DOES NOT constitute the proper or effective use of correction based condtioning/training and thus misuse of the tool.... it is a indicator of improper delivery of stimulus in hopes of acting as a true correction and as mentioned inappropriate use can simply and clearly be gauged by the need for continual use of addtional correction based tools/methods.

A dog that has been taught properly on a prong collar (1 week or much less for a knowledgable expert) or with the use of any other aversive should no longer need to be administered a aversive stimulus IF conditioned properly.... so a choke collar or any other type of training/correction based tool/collar should no longer be needed after conditioning behavior with a prong collar..

hope that helps...
