Ground anchor for dogs

A handy ground anchor keeps your dog in place.

A handy ground hook for hunting, for example! The rotating retaining ring prevents the strap from tangling.
The ground hook is twisted into the ground, for example, into the lawn, so that the twisted part sinks completely into the ground. The dog is attached by its collar/harness to a wire or leash, which is then attached to the swivel ring around the hook. There is a handle at the top of the hook for twisting it into the ground.
