Training method has direct welfare implications for dogs, with positive reinforcement-based approaches producing better welfare outcomes, lower fear and stress, and stronger human-animal bonds than aversive methods.
Training method affects dog welfare through both the immediate emotional impact of training interactions and the longer-term consequences for fear, anxiety and aggression. Dogs trained with punishment associate humans and training contexts with unpredictable threat. Positive reinforcement builds confidence and cooperation. The welfare case for positive methods is supported by extensive scientific evidence.
