I don't understand, I have tried to look at some sights and I did a forum search but I don't get some things. Do you actually ever say the command? I can't tell from what I've read, all I see is the rewarding part? How are they going to know you want sit, won't they just sit all the time for a reward? Do you say the command, they do it then click and treat? Also can you click, and while giving the treat say good girl or something, that way they at least kind of associate good girl with the treat in case you don't have the clicker handy? Lastly where can I buy a clicker?
