There are possible dangers to using a dog zip line. Be sure to test it and monitor your pet closely to see how it behaves with the contraption. For example, make sure your dog isn't getting wrapped up in the leash. And help your dog feel comfortable with the system by standing by it for the first several uses.
Attaching the leash of the zip line to your dog's collar is another danger the system poses. We highly recommend using a dog harness. A harness fits around the body instead of the neck, which could be harmed if pulled by the zip line.
In addition, any kind of zip line or tie-out system that prevents your pet from running away will also limit its ability to get away from predators or other aggressive animals. It’s very important to always keep a watchful eye on your fur baby when it’s tied outdoors.
