Research has shown that any creature—whether a dog, cat, dolphin, parrot, fish, horse, llama, or person—is more likely to learn and repeat actions that result in consequences it desires and enjoys. So clicker trainers provide consequences desired by their animal in exchange for actions or behaviors desired by their trainers.
Do clickers and treats need to be used for every behavior, forever?
No. Once a behavior is learned and on cue, there’s usually no need to click, as the animal understands the behavior. Clicker trainers can maintain the behavior by replacing specially good treats with occasional and less intensive rewards including a pat or praise. Learned cues and behaviors are also maintained by real-life rewards: for example sitting quietly at the door is rewarded by opening the door so that the dog can have a walk. Clicker trainers then save clicks and treats for the next new thing they want to train.
