I have/am trying to train Reuben to walk to heel and sometimes he is really good and other times awful, especially in new places and first walk etc. I will keep perseveering and am patient. However he is so strong now and my shoulder is really hurting and maybe I need something to help me along or at least use in the morning when on the school run and holding school bags, dog and child! I have never used a Halti or anything as I was worried that this would just mask the problem and not teach him how to walk nicely. I have tried a half check collar but am not convinced this has helped much and I don't want to be yanking him about.
