I highly recommend Andrea Dugan's workbook, Holistic Dog Training, The Foundation.
She is coming here to teach a seminar in Feb, and I am SO excited. She helped me work with Frodo's barking, by teaching him eye contact and focus.
If you are interested, she gave me permission to print the book, and we sell it for $20. Proceeds go to Hull's Haven Border Collie Rescue
