My shnauzer is already 1.5 yrs old and has been trained on basic commands (sit, stay, down) without the use of a clicker. I see that all the classroom lessons are based on the use of clicker training. The question is whether it'll be easier for me to start introducing a clicker to my grown dog or is it easier for me to try training the other commands without a clicker? Could I know your thoughts? Thanks.
