Don't get me wrong, I used Water Dog as my guide for two Labs in the past. But it's seriously lacking in quite a few areas. NOT JUST in the use of an ecollar, but in finishing out FF (Wolters only gets as far as kind of a formal HOLD (or maybe kind of an "informal HOLD"). He doesn't get into swim-by, water cheating, complex (or even semi-complex) blinds and the list goes on and on.

I think the most complete training books available today are (NOT in any specific order) are the Smartwork books, The 10 Minute Retriever and the Lardy Articles.
