Abby and Daisy have several different harnesses and I've never had this problem with any of them before, that's why I was so shocked.
Now that I think about it, I think sitting there, she was pulling back behind me and somehow wiggled out...when we're walking, there's probably more tension on the harness from her walking in front of me.
I'm glad it turned out OK too. Thank You
We definetly need the yorkie angels on our side.
