Yes, the earlier a dog gets to know how to lead as naturally as possible, the fewer problems arise later. By turning towards you, the dog also learns to orientate itself more towards you later when free running (frequent eye contact). But please also consider: Dogs, like children, learn through experiences with the environment. They want to interact, sniff, walk, and learn to assess themselves and others. It is therefore very important to give the dog these experiences.
With the STURMFREI, contact with other dogs on a leash is also possible by not tightening the neck (collar) or throwing it back (chest harness). This will help you avoid leash aggression in the long term.
