You don't acutally need to use a clicker to follow the same "clicker" method. Just replace the clicking sound with one sound or word to signify a correct response. Like - "SIT"...CLICK (or say "YES")..reward.."GOOD SIT".
I "clicker" train deaf dogs using a flashlight to replace the click. You could replace the click with the sound of your hand smacking your leg, or click with your tongue, or a word, as above..YES.
