Evidence-based dog training using positive reinforcement produces better behavioral outcomes and significantly better welfare than aversive training methods.
The science of dog training has become clear: positive reinforcement methods work, and aversive methods cause unnecessary suffering. Dogs subjected to shock collars, alpha rolls, leash corrections, and intimidation-based techniques show acute and chronic stress responses — elevated cortisol, behavioral inhibition, redirected aggression, and impaired learning. The American Veterinary Society of Animal Behavior (AVSAB) position statement explicitly recommends against punishment-based training and dominance theory. Positive reinforcement training — rewarding desired behaviors with food, play, or praise — is effective, strengthens the human-animal relationship, and causes no welfare harm. The persistence of aversive training is primarily cultural rather than evidence-based.
