To stop a dog from pulling on the lead, consider using a no-pull or training lead. No-pull leads reduce the pressure on your dog's neck and guide them back towards you when they pull. Training leads, on the other hand, are designed to offer greater control, helping you reinforce proper walking behavior. They are often longer than standard leads, allowing you to guide your dog more effectively and encourage good walking habits. Consistent training and positive reinforcement are key to successful leash training.
