Every animal, from fish to primates, has needs and wants – and that is precisely what facilitates training. I am a firm believer that virtually any animal can be trained, at least to some degree, with the right approach. That’s where positive reinforcement comes in. Positive reinforcement is the use of those wants or needs as rewards for behaviours that you want to encourage, and the simple lack of reward for undesirable behaviours. When using the positive reinforcement method, you never introduce any element of punishment.
