I do! But after a while I transferred from a clicker to a clear word (exactly the same concept but instead of a click, you say a short word you never say any other time. I use "yatta!" - Japanese for "yay!"). Only because I'm really scatterbrained and can't be trusted to have the clicker on me.
Look up Karen Pryor and/or Susan Garret for good resources. The most important thing is to spend a few days building the association between clicking and treats.
I use clicker training! I dont use it for basic obedience, just a treat should suffice. I use it more for other things like working through fear, strangers etc as the click is reassuring to her and she knows shes doing well when she hears it. I bought a clicker i can hang round my neck and its there whenever we go out.
Speaking of word training, I use the greek word for come 'éla' when doing recalls. It sounds so much nicer than shouting come lol! x
I'm with Quill! I bought Karen Pryors clicker. But, I am sooo uncoordinated that I don't click fast enough! So I just say good boy, which was a poor choice of words - but it just came out and I didn't think he would make the connection! So now, if I say good boy, he looks up at me as if to ask "where's my reward?"
Clicker training can be done without the actual clicker. The principle is the same. You most always have your voice available, and the quicker you can say "yes", Yada, or whatever, the better after the pup does the desirable action. I use yes!
