I agreed with Dr Dunbar to.
I do use a ah ah noise but tend to use it to get the dogs attention and then ask for a incompatible behaviour to the "bad" behaviour they were displaying so i can reward that.
I dont use the word no as I dont think it gives my dogs enough information and is too general.
Im not a computer and of course do at times say ah ah/ pack it in and dont redirect but my dogs do get the jist that i want them to stop what they are doing.
My dogs also have a non reward marker that comunicates to them when i think something i have asked for isnt good enough.
I do agree that clickers although a great tool are not the be all and end all of dog training and there are some things i never use the clicker to teach I use my voice and body language.
I agree with spanielcrazy that voice can have a big influence on a dogs reactions particulary in situations where they are stressed.
I do talk to my dogs (quite a lot

) but they are intelligent enough to know the difference between me blathering and me training them.
Personally I DONT want to train like a computer and I dont think it improves our relationship with our dogs or respects them as individuals. How can training be fun if someone is just stood there clicking

Jack would rather have a "good boy" then ten clicks and treats and brie would rather have a big cuddle and told shes a princess

those words mean something to them and are just as much of a marker as a click. I could click before I say them but I dont really see a reason to as to me its just more natural. I deliberatley get my dogs to associate praise and verbal markers with their actions as personally i think it improved their bond with me and makes training more interactive.
Sorry if I interpreted what was being said wrong its late and I skim read the articale while listening to the video and playing with seth (while telling him what a clever boy he was).
