Clicker training was developed in the 1940s as a way to communicate with dolphins and whales. These days, clicker training is used for all sorts of animals, including dogs, cats, rabbits, horses and more. Because rewards (like treats and praise) are a big part of it, it’s a positive reinforcement training method. It’s simple to do and helps to create a shared language with your puppy that you’ll use together for the rest of their life.
In a nutshell, clicker training helps your puppy associate the clicking noise with good behaviour. You’ll use a clicker to mark the moment something happens (in this case, the right behaviour) and then provide a reward. This ensures your puppy knows exactly what they've done to be rewarded and that they get good things when they behave well. Plus it motivates them to repeat the behaviour, again and again. Although you’ll start with tempting treats, as you move through your training and phase out the clicker you can start to use praise and pats as a reward instead.
Over time, your puppy will learn that the clicking noise means that good stuff is coming - so they’ll pay attention to what they were doing when the click happened, and will repeat it to get another click (but most importantly, another treat!). This is really handy as you train your puppy.
