I tried kibbles on the family dog, but she didn't get past the pincer grip.
Actually the point the operant conditioning people make (Karen Pryor) is that for many individuals of many species, it isn't the food treat that is so reinforcing, it's knowing that they 'got they message.' There is a video of a fish in a fish tank following a pointer, and totally being so into 'being right' that the fish totally ignored a tasty morsel that was thrown into the tank as a reward. The fish just wanted to 'get to the next level.'
Sound familiar?
