I am not familiar with this particular author, but any good dog training book shoud do, go to petsmart, or library or other good bookstores like Barnes and Noble or Borders etc. Take a look at house breaking books,(there is a House training for Dummys too!) The main thing is to be persistant and to hang tuff! Use a carrier or small pen while ya'll are out and let him out the first thing you get home! Keep a constant schedual with him. See about going again to the lessons at Petsmart and they can help with house training suggestions too.
