Yes, I've seen that. But I disagree with her assesment of NILIF. It is a GREAT system of training, especially with strong-willed breeds. It just takes consistency. WELL worth the effort! "Nothing -in-life-is-free" just means that before the dog gets anything, he has to sit, be quiet, stay...whatever you ask of him, before he gets whatever it is - his food, a toy, petted. He learns that YOU are the source of all good things, and he doesn't have to fight you for them. I really don't understand her objection.
