Free house training guide from Dr. Sophia Yin

As you have noticed, I think Dr. Sophia Yin is fabulous.  She has just released one of the chapters of her upcoming book, Perfect Puppy in 7 Days;  it deals with how to house train a puppy.  This guide to potty training is free, and excellent!  You have to download it, and you can't print it, but it's still a fantastic resource.
