Wow, I realize I am new here but that is a ton of info! I have 2 dogs, a lab/Border and Husky. Both pull like the dickens. I use a Halti and the pulling stopped and they walk with a loose leash. Now the 2 part problem, 1) they have learned that by backing up away from me they can slip the Halti's and 2) I am trying hard to transition back to a normal collar as I know the Halti's 'bug' them on their noses. Perhaps I am impatient but it seems at times to be going backwards.
