A locking leash device comprising the four main elements: the guide, the leash shuttle, the brackets, and the locking mechanics. A locking leash device is used to secure a pet animal, such as dog, to stationary objects, such as a pole, small tree, etc., and prevents the pet from tangling a leash about the point of attachment and/or wrapping up in the tree or pole they are tied off to, giving customers a tangle free experience with their dogs. A locking leash device is a portable, convenient to use, simple, lightweight, weather and rust resistant device with interchangeable and replaceable parts that are easy to assemble and remove and made of a resilient material, so as to minimize stress on the dog. It is an environment friendly locking leash device that does not damage any part of the tree, and can be used in many different areas, such as campgrounds and parks.
