You are so right Kat, this is the kind of BS that ruins it for all good dog owners. She obviously has no clue what her dog is doing if he is that far ahead, and ya know, unfortunately for her dog they will run into the wrong dog with owners who don't care as much as you two, and her dog will get torn up. Then she will be blaming EVERYONE except herself.
Sorry a good day had to be ruined by this.....tom
