Just found this thread. I have been reading a book that came heavily recommended by a lady from the OB Club here in E'ville "Competition Obedience: A Balancing Act" by: Judy Bryon & Adele Yunck. I haven't gotten far into yet but so far so good!! Even if I decide not to go into competition ob, this book has so far been VERY informative, easy to understand and a great training tool!!
