There are no bad dogs

Barbara Woodhouse, I think said this, and it bears repeating. I recently read a tag line somewhere, and it said "life is too short to work bad dogs". What does that mean? Well, we know what it means- just what it says; that working lower quality dogs ain't worth it. What makes the dog lower quality? Because it's weak? Because it's not stylish? What? I want to know. I think that statement is a load of hooey.

I have worked with many good trainers, and some of the WORLD's best at that, and they would never say this- they say that they learn from each dog that they train. There are no bad dogs.
