126 Martingales are great, and CHEAP!!
Correct me if im wrong mods. Honestly if you just want to manage the leash pulling; ie; you dont care if she knows a basic heel as long as she doesnt pull; then get an ez walk harness or a pinch collar (understand that we DO NOT yank on a pinch collar it is only there to make her uncomfortable if she pulls on the leash). My two cents.
