Here’s helpful video on how to start clicker training from a skilled positive reinforcement trainer:
What if I don’t have a clicker?
While clickers can speed up the learning process, you can absolutely still do positive reinforcement training without a clicker.
If you’d like to take advantage of the same learning principle, you can just find an alternative marker to replace the clicker. I’ve seen people click their tongues, use Snapple caps or clicking pens, or just say the word “yes” or “mark.” Just make sure that you can quickly, easily, and clearly demonstrate the cue. Timing is critical for this style of training, so you don’t want to be fumbling around with a noise-maker and miss the behavior.
