The evidence overwhelmingly supports positive reinforcement training as superior to aversive methods for both welfare and training outcomes.
Training is unavoidable for companion animals living in human environments, making training methodology a high-impact welfare decision. Aversive methods including shock collars, prong collars, and alpha-dominance techniques cause measurable suffering and compromise the human-animal relationship. Force-free training strengthens the bond, reduces stress, and produces animals who actively choose to engage.
