There is no doubt that the interactive Kong toy works as show here by Smudge. We have never seen Smudge show any interest in any kind of toy, interactive or otherwise. Only "problem" is she is resource guarding and the others just don't have any chance to share the new toy.

Dog Training Collars & Harnesses : Fitting an Easy Walk Dog Harness

A great product for bigger dogs and dogs that pull, but as always fitting is very important. 

Clyde with his new, fitting image as a scholar 

Clicker training lesson 1: Introduction to the clicker and establishing eye contact completed. Well done Clyde.
It seems that it will take a while longer with Digit as he is showing and aversive reaction to the clicker sound. I might have to re-think the training method for Digit. I will give it to the end of the week, just doing clicker introduction with him. 
Any ideas that can help?
