Dog training question.

My question is: has a shock collar worked for you in the past?

Probably a good place to start. As you know I adopted the Malinois and he has a very aggressive prey drive (still working on it, lol) he does pay attention to the collar.

I would suggest a Mini Educator with tone, vibrate and shock.

When using the shock, set it as low as possible to the point the dog reacts. My Mal will respond to a 5-7 (out of 100) on the shock when training. When you go for walks you may need to pump it up to 30-35 maybe more depending on attitude to dissuade her from overriding your voice commands.

When you train, train her on the "leave it" command for anything you want her to, well, leave alone, lol. Once the dog learns that command you should be able to command "leave it" and she should do just that.

Do a search on YouTube for Larry Krohn videos, he does a fantastic job of explaining different commands and how to incorporate the collar into training. He gets some amazing results.
