Note: Usually Automatic Retractable Leash Cannot Be Pulled to the End at a Time! During the Use Process, Customers and Friends Must Keep Locked and Let the Dog Move Freely, So as Not to Cause the Dog to Rush Forward Suddenly, Causing Damage to the Movement Caused by Violent Rush, almost All Automatic Retractable Leash Have This Weakness. If You Mind, We Recommend That You Use Common Style Traction Rope. Thank You for Your Understanding and Cooperation!!
