I didn't watch the program but a dog trainer I know and respect was complaining about it on Facebook. She made it sound like the was a lot of aversive training going on in the program. Shouted NO and yanking the dogs around - apparently one in that episode got bitten for taking the advice of the trainer?
I'm I'm two minds about the ethics of an aversive No. I rather suspect my own dog trainer (we go to a weekly class) trains me like her dogs(!), she doesn't give me any attention or feedback on me saying no, but every piece of advice follows the ignore and replace rule of thumb. When I first got this dog I didn't know any better and a couple of times shouted and growled at her. She cowered and I felt bad because although I wanted a well behaved dog I want a good relationship with my dog, not a dog who is scared of me. I definitely don't do that any more, my "dmr" is fairly consistent, but I do still use a calm and quiet and elongated "nooo" as ive described. Whether I'll come around to not using a no as an interrupter, I guess time will tell.
I try to think like the animal interacting with another of their own species. Dogs definitely have a "No" amongst their own kind. If I were a dog would I want to be around a boss who was quick to say "NO! FUCK OFF YOU ARSEHOLE!!" and yank my collar often, in a loud and scary way? Or would I be happier with a boss who mostly praised me for the stuff I got right, and occasionally quietly said "hmm no actually not like that. Here, let me show you what I did want."?
Of course I'm still wrangling the fact that might I prefer even more a boss who ignored what I did wrong but encouraged me to do right? I stil genuinely don't know if I'm anthropomorphising too much there, or if actually I'd like to know when I'm it doing it wrong - I think I would. I have a lot of time for my current boss, she's lovely and she without realising shapes our behaviour by only offering what she wants not pointing out what she doesn't. Equally the only times she frustrates me is when I know she's pussy footing around a delicate subject and I'd much rather she was direct with me! We have another boss who tries but falls a lot shorter of the mark, and he is stressful as hell to work for. We get a lot of "no" in the form of "hmm, I didn't mean for you to do it that way, here's what I want next time" and it has resulted in a lot of stress because somehow despite his best efforts to communicate goals clearly and our best attempts to fulfil them, we always seem to displease him and it never seems good enough. There's no surface "No" or aversive from him, but we all perceive the thinly veiled aversive anyway.
I guess what I'm really mulling over is that my own experiences with humans a well as with animals are causing me to reflect on how to be the owner my pets want me to be, although I'm also very aware that human experience and cognition is not the same as doggy. 40 years ago I had lovely ex gundogs who were certainly trained with aversives both before and since I got them, and they still genuinely seemed happy non-stressed members of the family. Since then training and learning theory has moved on and I wouldn't dream of using aversives like was acceptable back then - I guess we can all only do the best we can with the tools we have got.
