It is, but then isnt a fix, what the ecollar does......if taught properly.......is an extension of the check cord. It will alow a fair correction with the dog.....afterdog has been taught what the collar is being used for.

Now old schoolers would do several things alot harsher to the dogs for breaking.

Times have changed, if you do the foundation properly an dont cut corners, and dont be in a big hurry to get the check cord off, it will all show itself over time. You be fair to dog an it will be fair with you, teach the what an how, let the dog show you it is understanding the what and how, and there is not any confusion, between you and the dog. During the steadying process, put the dog in a sucessful environment.....and it will succeed. Dogs will tell (show) you when they are ready to go to he next level.
