Training method choice has significant welfare implications for dogs. Evidence comparing positive reinforcement and aversive methods consistently favours force-free approaches.
Training method welfare is not merely a preference question. Aversive methods cause measurable physiological and psychological harm. Suppressed behaviour from punishment may be mistaken for training success while underlying anxiety remains or worsens. Dogs trained aversively show higher bite risk in ambiguous situations due to conflict between desire to escape and inhibited response. Force-free training is not just kinder - it is more effective and produces more reliable behaviour.
