I used the Koehler method on Rocky after
trying the positive methods.
The Koehler method worked the best
for him.
I have learned to combine the different
methods in my training.
I now brush up with using mostly positive training with Rocky, but the Koehler method was a great fondation. In my case Rocky was a hard core butt head.
You either hate the Koehler method or you don't.
I think a lot depends on the personality
of the dog on which method works best.
I prefer a combination of methods,
so I pick and choose from each.
