＇Dog traction rope breast strap＇ is the safest small dog leash. Small dogs will be injured with the collar because of their young bones. Also, because of their small size, it is easy to get rid of the collar when using the collar, causing the dog to get lost. When the pet chest rope is used, the tension will be evenly distributed on the front legs and the chest to prevent strain. There are 3 adjustment buckles on the rope to adjust the fit size and prevent the dog from getting lost. There are sizes S and M to choose from. The leash can be adjusted in two lengths, with a total length of 1.3 meters. You can put on the D buckle to shorten the leash by half.
