http://www.bbc.co.uk/programmes/p00pj6dwA warm and intriguing miscellany about the dog-human bond, spiced up by archive clips from past BBC programmes which have the capacity to amuse and cringe at the same time. Moustachioed 60's and 70's professors - even one with a monocle! - spouting forth with plummy voices about domestication, history, anatomy, behaviour and training. Some clips from PDE2 including the pop-eyed evangelist vet, but don't switch off there, the best is yet to come.
Second half starts looking at behaviour in detail - from the Belyaev foxes through to work studying village scavenger dogs. This essay is not afraid to show clips from days past when we got it all wrong; in fact it goes into quite some detail about how domestic dogs are not wolves, and supports modern methods of positive training. We see Barbara Woodhouse with a very stressed GSD, and Jan Fennel, plus snips of Dog Borstal as we are advised that this style of training does not really work, and positive methods are the way to go.
I don't think there has been anything on TV before that has encapsulated modern thinking to this degree; John Bradshaw is a voice of [good] reason, and through him we learn that military dogs are only trained with kind methods - because human lives depend on it.
