It’s not unusual for some dogs to have “clicker aversion,” especially with box clickers, as they make a loud, sharp sound. Start with the clicker behind your back, or in a pocket, to muffle the sound at first. If you’re trying to clicker train your dog and he or she seems to be worried about the sound, please stop using your clicker immediately. Some dogs show few signs of discomfort before suddenly running from the room when the clicker is presented; others look increasingly uneasy with every click. Better to stop sooner rather than later, as the problem is harder to fix if your dog has developed a phobia.
Next time you’re ready for a training session, start with your dog in a different location using different treats, no clicker in sight. Give a quick “smooch” sound with your lips instead of the clicker… if this worries your pup for some reason, just switch to the word “Yes” instead. If you’d like to go back to a mechanical clicker, try to find one that makes a softer sound, or even use the top of a click pen. Don’t attempt to reintroduce the clicker, however, until your dog has had a few weeks of non-clicking clicker training!
Surprisingly, dogs who are bothered by the sound of the clicker at home seem to cope perfectly well in a class or an environment where the other dogs are getting clicked.
