I got another gun dog training book out of the library yesterday. There are only two so my choice is rather limited.
In this one, same as the last one, and in various other non gun dog training books there is an extreme anti sentiment by some towards using treats during training.
Why is this?
Of course what is fine apparently is dragging your dog round by the scruff of it's neck, shaking it, glaring into its eyes at close range etc etc 
After reading that bit I turned to the front expecting to find the book had been published in 1978 or some such. Nope, 2006.
What is it that the anti treat people are worried about? I'm genuinely interested. Is it to do with dominance theory or something else?
