I used this on my last dog a 2 year old rescue Lab Mix. that knew nothing when I got her.
With this DVD set as a guide she turned into a wonderful dog. EVERYOne asked how I got her to be such a good dog. She was a very happy dog and went everywhere with me. Totally trustworthy Off leash.
I could have her lay down and walk off 3/10 of a mile and she would stay until i blew a whistle. She would stay when people or dogs walked past her a few feet away.
If this does not work for you it is not the dog it is You not following the instructions. Gary K
