What are the best practices for safely securing a dog with a cable while outdoors?

When securing a dog with a cable outdoors, it is important to use a strong and durable cable that is appropriate for the size and strength of the dog. The cable should be attached to a secure anchor point, such as a sturdy tree or post, and should allow the dog enough room to move around comfortably but not get tangled or caught on objects. Regularly check the cable for wear and tear, and never leave the dog unattended while tethered. It is also recommended to use a harness rather than a collar to prevent injury to the dog's neck.
