I was kind of disappointed by this book because it didnt tell me anything that I didnt know already. The one thing that I did learn was that you cant really potty train a dog until its 4 months old because it doesnt have bladder control...which I actually read in another book later. Honestly, the best way to potty train your dog is to leave him/her for a weekend with a friends dog that is already potty trained. They learn things from a pack so much more quickly then they do from you. My dog used to go in the house at least 2 times a day, I went out of town and left her with my friend who also has a dog and she came back scratching the door when she needed to go. That following week she only went one time in the house, it was AMAZING. Sorry...a bit of a tangent, but thought some people may find it helpful. All in all...skip the book and just google your info youll learn everything thats in this book.
