Hi, I was just wondering if you let your chi's of the lead when you go for a walk? I have recently adopted a one year old chihuahua and she is tiny. Her previous owner used to let her off the lead and when we go out she clearly wants to run free but I have had a number of scary encounters with over exuberant bigger dogs and a terrifying one today with a lurcher who clearly thought she was a rabbit!! I feel mean keeping her on the lead when she clearly wants to run but terrified that something will happen to her. Just wanted to know what the general consensus was on the subject. Thanks
