I have been working with Hunley to not pull when walking but he seems to be a puller. And for a little guy he is strong and my arms are tired after we walk, even for a short time. I have been incorporating all techniques I've read up on to get him to stop pulling, which only work for about a second (not even long enough for me to say good boy when he stops for a breather) and he's off pulling with all his might again. I have one of those step-in nylon harnesses you can purchase anywhere, but was wondering if the strap that goes down his chest is what is making him want to pull?! I was thinking of investing in a buddy belt and wanted to know if this may encourage him to NOT pull. Any input is greatly appreciated. Thanx.
