Clicker training was orignally used for marine animlas. Trainers relized that they weren't always able to get the food to the animals right away. So they came up with clicker training. Clicker training is mainly just comunication. And when training your dog comunication is key. To do clicker training first you need a clicker. You can usually find these at any local pet store. Once you have a clicker you want to get your dog to understand that the clicker means a reward is coming. To do this, tell your dog to sit, when he/she does, click, and reward. If they don't know sit you can just click and reward, click and reward. Keep on doing this until you think your dog understands what the "click" means. If you still don't understand, you can ask me questions in a comment. Good luck with clicker training! Happy tails!
