I recommend "Breeding to Win" by Patricia Craige Trotter. While Pat's breed is Norweigian Elkhounds, much of what she talks about is applicable to our breed.
Saw her seminar last night and I couldn't agree more. "Born to Win" is on my "to buy" list ASAP. She is judging at our local show this weekend. I think what she discusses applies to every breed, not just her own.
