Positive reinforcement training methods, which reward desired behaviours without punishment, significantly improve animal welfare across species while achieving better behavioural outcomes than aversive approaches.
Training methods that rely on punishment, pain, or fear cause genuine welfare harm, even when effective at producing behavioural compliance. Animals trained through aversive methods show elevated stress indicators, reduced willingness to engage, and generalised anxiety that affects their overall wellbeing. Positive reinforcement produces behavioural reliability alongside positive emotional associations with training contexts. The evidence strongly supports welfare-based training approaches across all species and training contexts.
