My wife bought a dog harness with that effect. It has a somewhat loose strap at the front that glides back under the dog’s chest and presses the dog’s “upper arm” to its chest when he pulls forward too strong. Works great, and our dog doesn’t seem to mind very much. (The leash is fastened to this strap, btw. In case someone would be looking for such a device.)
