i don't want to get down on any method, i would like to say though, that no matter what, i see some methods of Koehler as full blown abuse. such as sticking the dog's head in a water filled hole it dug to get it to quit digging.

sure, i use a lot of praise, but i also sometimes use butt swats. (not that i've had to do that in a long time.) praise works a lot better, but sometimes they are just like children, and it is the only way to get their attention. that and a LOUD voice.

most the time though, praise is the best teaching tool. and talking things though w/ them. it's amazing how much they actually do learn.

my biggest piece of advice is establishing a NO and Good. those will be the biggest factors.
