Dog training methods vary widely in their welfare implications. Understanding the science of learning and its welfare applications helps owners and professionals choose methods that are both effective and humane.
Dog training methods are a direct welfare issue because training occupies significant time in dog lives and because aversive methods cause measurable stress, fear, and physical pain. The scientific evidence supports positive reinforcement not only as more humane but as at least as effective as punishment for virtually all training goals. Dogs trained with punishment show higher stress indicators and more behavioral problems than those trained with rewards. There is no welfare-neutral reason to use aversive methods when effective alternatives exist.
