My book, Force-Free Gundog Training:  The Fundamentals for Success, is now available on Amazon (world-wide!).  If you do pick up a copy, please do leave an Amazon review to give me some click and treats and make it more likely that I will be motivated to get to work on the next book!!  I have a proof left over - a copy of the book which is exactly the same as those sold, except it says 'Not for resale' across the front.  I'm going to draw a name from a hat for it!  If you'd like to enter the draw, please email me your training question(s) at jo@dogworks.org.uk The article on variable reinforcement referred to in the podcast, is Doesn't Intermittent Reinforcement Create a Stronger Behaviour? by Eileen and the dogs.
