LOL just like everything to do with dogs (& people)there is no size fits all method of dog training. When I started(back in the mists of time)99% of training was done a la military/police handlers, chokers the norm lots of heavy handed placing of the dogs. As I was only 8 years old there was no way I could pull & push an adult GSD around & so with the help of a hepherd who used GSDs in Ireland I took my first steps in motivational traning.
When I was 14 I was loaned a bitch to train who had been through the hands of a then all too common dog breaker & in his kennels she was beaten into obedience with a leather strap & choker. She wasn't obedient at all just terrified. So I could not put anything around her neck other than the flat collar she always wore & no way could you put a lead of any strength or weight on the collar. She was also terrified of even being touched(she had been returned as a fuly trained dog)
So I could only attach a very light cord to her collar & I was a a loss to even try to help her. I struck lucky again in the form of a RAF militarypoliceman(not a dog handler)who had self taught himself to train his very nervous white sable GSD using a touch method(yes this was in the 1960's !!!)
With a treat in my hand & the bitch unfed I sat & taught her to touch her nose to my hand for the treat., using this as a starting point. I progressed to holding it about her her head & moving it backwards until she sat & then downwards until she was in a down. We slowly progressd into heelwork again holding the treat so she could touch my hand for it & eventually she would just watch my hand. We worked obedience & got placed in every class we were in but never won as we always lost run offs
When I got my first BC she was tiny(1/2 inch over a sheltie sizewhenadult)& by then I had my back problem(long story caused by an army cadet abseiling into me whilst I was climbing)so I used the same technique & it must have worked as by 8 1/2 months of age she was out of Novice winning 8 beginners & seven novices & she was C only at 2 1/4 despite having 6 months with no retrieve due to being attacked whilst working by a GSD.
I have used this method on all my dogs & whilst not as instant as clicker training is supposed to be, I find it builds a real relationship that gives my dogs the confidence & trust in me they shoud have. I only have my dogs on leads at dog shows, training club & when legally required I never train them on lead not even for recalls or stays.
Like I said this method will not work with all handlers, but they do for me so I personally have no need for a clicker.
BTW the sheep learnt to flock to the clicker(using the dog as a stimulus ;) ) & also to follow me I felt quite like lil Bo Peep :D
