What is the use of dog shoulder straps?

In short, the shoulder strap has a relatively large contact area with the dog's body, and when towing the dog, the force on the entire shoulder strap is relatively uniform for the dog, which makes the dog more comfortable to wear. Moreover, the stress point of the shoulder strap is not located on the neck of the dog in the complete collection, so the dog is also relatively willing to wear it.
Strictly speaking, a dog's shoulder strap should be a restraint tool, especially when outdoors, by wearing a shoulder strap and pulling the traction rope properly, it can better control the pet dog within a safe range and prevent it from experiencing safety issues.
