I taught the word contact with a small lid and treat on it to teach Tiz to stop on command and then transfered it to the contact. I hope I explained this right.
I had just started learning with clicker for agility with Scout but we only did begining class and had not started a class to really transfer it to equipment when he became ill. I am really happy with clicker training it did not take him very long to understand what I was asking of him.
