Very nice and sturdy leash. HOWEVER, it is not adjustable. Unless it means that it should be worn by a dog with such a huge neck that we would have trouble putting it on him from the beginning. The two metal clips "find" each other, so the leash cannot tighten around the neck.

Very beautiful and durable! You may want to get a smaller size than usual. Measure the diameter. It doesn't work as a regular choke, it stops.
