Happy it worked out for you. Interesting with the use of the two leashes. I would find that part awkward -but that is just me. I do think whatever tool is used - a harness or a collar - that training has to go along with it. That is why I went with the Walk In Sync harness

(front ring harness - one leash) - a leash and training videos come with it. I do agree with you - the harness makes walking a joy.
