Put the shock collar in the safe until she absolutely knows what she is supposed to do; and that is a good way down the road.
"Training Spaniels and Retrievers": Ken Roebuck
X2, I haven't read/seen this book/DVD, but I recommend highly his "Gundog Training Spaniels"
http://www.amazon.com/Training-Spaniels-Gun-Dog-Staff/dp/B0013QTSQ2 I apply this method to both Spaniels and Flushing Retrievers. If this one is anywhere near as good it should be great. Great advice on the E collar as well, and when you do bring it out be sure you collar condition her properly before actually using it for correction
