Bought this after our active working cocker spaniel had a front leg amputated. She continues to pull when on the lead, but this harness really helps. It is soft, comfortable and easy to put on. I think your sizing needs to be reviewed. A medium was too small and the large is only just big enough!!
Lovely strong and comfy harness for my dog. The step in feature is good for us as he doesn’t like things putting over his head. Easy to fasten and unfasten.
