Probably the most commonly asked about problem! Here are RPD's
favorite recommendations. Note that the books in the previous section
also oftnen cover housetraining.
Evans, Job Michael. _The Evan's Guide for Housetraining Your Dog_.
Howell Book House, 1987.
Evans was a monk at New Skete for some years. He discusses all
aspects of housetraining puppies and dogs, giving many
constructive solutions for all kinds of specific problems.
Smith, Dr. M.L. _You Can Teach Your Dog to Eliminate on Command_.

It's a small paperback but full of excellent advice on how to
get the right timing etc. to give the command. Great assist to
housetraining in general.
