The evidence for reward-based, force-free training methods demonstrates clear welfare advantages over aversive methods. Understanding this evidence guides better training choices for dogs and their owners.
Training methods that use pain, fear or intimidation to suppress behaviour impose welfare costs that extend beyond the training session itself. Dogs trained with electronic shock collars, choke chains or physical punishment show lasting increases in anxiety, reduced ability to learn in similar contexts and increased risk of redirected aggression toward people or other animals. The welfare cost is not merely the acute pain of the aversive stimulus but the chronic fear state associated with training environments, handlers and equipment. Welfare-positive training using positive reinforcement achieves the same or better compliance outcomes while building the dog's confidence and trust relationship with handlers, improving welfare across all contexts.
