I have "The Hungarian Vizsla" (Second Edition) by Gay Gottlieb, and also "The Vizsla" (Second Revision, 2000) by Bernard C. Boggs. Both are great books, full of information. I think I especially like Boggs, though... It's sort of like the Bible for Vizsla owners. Not that I don't like Gottlieb, don't get me wrong. I guess I would suggest either one of them, really.
