A clicker is just a marker. Saying the word "Yes!" has the exact same effect if you use it correctly (just like the principles of using a clicker ).
You are just to quick for me LOL. Thats what i was going to say.

I too would start associating the clicker with good stuff like getting fed and playing etc . And if you have not done so i would 'load the clicker', which is pretty much sitting down with the dog and doing a reptition of 'Click, Treat' for free.
