Scientific evidence increasingly supports positive reinforcement-based dog training as both the most effective and most welfare-positive approach, with aversive training methods causing welfare harm and behavioral deterioration.
Dog training methods have significant welfare implications that extend beyond the training session itself. Dogs trained with aversive methods including shock collars, prong collars, and physical corrections show increased fear, stress responses, and conflict behaviors compared to those trained with positive reinforcement. The welfare harm of aversive training is not limited to the physical sensation but extends to the chronic anxiety and behavioral inhibition it creates. Dogs are more likely to show displaced aggression when trained with punishment, creating both welfare and safety concerns.
