Hmmm - probably not the best podcast - mainly because Clive Wynne seemed to be trying to teach you the obvious at times! Even so, he does seem to genuinely want to understand this phenomenon, and to me, that is the important thing. If dogs don't use Ψ to do this trick, I want a reasonably watertight explanation of how they do it!
One of Clive Wynne's big ideas - mentioned several times - is that dogs pick up on what articles their owners are taking out with them. A simple control for this would be to ask the owner (sorry, I forget her name) to take all her gear with her (assuming she can fit into the boot of her car) every time she does a test.
