Query: Created a welt under my dog's front leg

I loved the idea of this harness because I had tried the muzzle type of gentle leader and my dog (lab) still pulled. But I noticed after using this harness for 2 weeks that my dog developed a raised and bleeding welt under his front leg (where the harness loops under his chest). As a result, I am back to a regular collar.
