Hi Ceejay,
It's interesting as Kendal Shepherd has continued the work on canine communication and followed on or added to Turid Rugaas (website here:
http://www.canis.no/rugaas/ ).
You're ahead of me as I've not actually got the book, although I do have notes from my "canine aggression understanding, handling and treating" lecture with her :)
She showed some very useful video clips including one of her grooming her dog who wasn't very happy about it (showed lots of signals and discomfort levels rising) and then showed how the problem could be addressed very simply by offering him a chewie whilst he was being groomed, which immediately showed how he moved right down the ladder. He was still showing some discomfort but far less and was much happier.
I still tend to think that some of the signals are very much calming and coming from that side, but then when you think about it, why would a dog feel the need to calm ? and so we are off up the ladder again! ;)
