Hello and Welcome to YT. "Yorkies For Dummies" is the first one I recommend."Yorkshire Terriers: A Smart Owners Guide" is the second book. These are excellent resource books .Another book "How to Housebreak Your Dog in 7 Days" Is very helpful. They are not as easy to housebreak. Here is the schedule that they are using. It seemed to work for Galen. Good luck
