I have been wondering about this too. We have a bigger dog would has one. He stays in the yard very well. He hasn't worn the collar in 6 months. I don't let Bella out unless I am out there with her on a rope. What I worry about is the times she darts out when we open the door. We try to be careful but with four boys and friends in and out we can't always. She just takes off and goes far. She knows she is not supposed to be out and well not let me get her. I am worried she will get hurt. |
