Training method has a direct impact on dog welfare, with positive reinforcement approaches producing better-welfare outcomes than punishment-based methods, including reduced fear and improved learning.
Training should improve dog welfare by building a positive relationship and equipping dogs with skills to navigate their environment. Punishment-based methods including shock collars, prong collars, and alpha rolls cause pain, fear, and anxiety, compromising welfare during training and potentially damaging the human-dog relationship long-term.
