The choice of dog training methods has direct welfare implications, with scientific evidence strongly supporting positive reinforcement approaches over aversive techniques.
Training method choice has direct welfare consequences for dogs: aversive techniques (choke, prong, shock) work through pain and fear, causing measurable cortisol elevation, stress behaviours, and in some cases lasting fear associations. Positive reinforcement works through reward, creating positive emotional associations with training and owners. The scientific evidence is clear — there is no situation in which aversive training is welfare-justified given the efficacy of reward-based alternatives.
