Training methods that rely on pain, fear, and punishment cause measurable welfare harms in dogs, while positive reinforcement-based training achieves equivalent or better results without these costs.
The debate about dog training methods is sometimes framed as a matter of personal preference, but the welfare evidence is clear: aversive methods cause measurable psychological harm. A dog trained through fear and pain experiences significant welfare costs during every training session. The argument that these methods are necessary for specific outcomes (protection dogs, working dogs in extreme environments) has limited evidence and does not apply to pet dog training. Choosing a force-free trainer is a direct welfare decision for your dog.
