Works great. Ringer was already trained in 10 or so commands prior to me getting a clicker and a couple books and now I am able to speed up his delivery on the commands that I couldn't do before.
Skylar, adding the clicker doesn't change the reward. All the clicker does is identify when your pup has done something right. How you reward the good behavior is still up to you. You can praise, treat, play tug, etc.. after the click. The great thing about the clicker is the 'click.' The click is instantaneous whereas saying 'Good girl' takes a bit of time.
Only place I am still having trouble is on walks since Ringer gets so excited to see other dogs still and I haven't found any good info on using a clicker to train an alternate behavior.
