Positive reinforcement training methods produce better welfare outcomes than aversive techniques across companion animals, working animals, and zoo species.
The choice of training method is a direct welfare choice: aversive training relies on fear, pain, and discomfort to modify behavior, while positive reinforcement uses pleasure and reward. The scientific evidence is clear that positive reinforcement achieves equivalent or better behavioral outcomes while producing animals with lower stress, better emotional welfare, and more positive relationships with their human handlers. Welfare-conscious animal care defaults to positive reinforcement as the ethical standard.
