You can secure your dog using a strong tie-down and an extra long leash. Make sure the leash is not something that can be chewed through, especially if you have a larger animal with strong jaws.
As a precaution, always make sure to not leave your dog alone while tied down. This can be extremely frightening for your animal and can put them in grave danger if a wild animal were to come around. Also, be sure your dog has access to plenty of water and shade, or that they are adequately protected in colder, harsher climates.
