The training methods used on dogs have lasting effects on their emotional welfare; punishment-based methods increase anxiety and aggression while positive reinforcement builds confidence.
Training is one of the most significant determinants of long-term dog welfare because it shapes the emotional and behavioural patterns that a dog carries throughout its life. Dogs trained through punishment — physical corrections, choke chains, shock collars — learn to avoid punishment rather than gaining a positive emotional relationship with training and the trainer. This fear-based learning is associated with higher background anxiety, increased reactivity, and greater risk of fear-motivated aggression. Positive reinforcement training, which rewards desired behaviour and teaches dogs through positive experience, creates dogs that actively engage with training and with their owners, with lasting welfare benefits.
