Hi, I bought the online book Secrets to Dog Training, because I have a big Guardian dog, and she was very aggressive to strangers in our house. I knew she could be trained because her mother was not aggressive. I got several good tips from the book as well as a personnel email on how to correct her behaviour. It worked and she is now much much better. I am
very pleased and satisfied I bought the book. Thanks a bunch Daniel for doing what you do.
