A leash-with-variable-anchor may have two opposing fastener structures, one for removable attachment to a collar or to a harness and another for fastening back onto a portion of leash-with-variable-anchor, forming a closed looped structure, an anchor. The anchor may function as a handle. The anchor may also be quickly, easily, and safely attached to various articles, such as, but not limited to, posts and without a need of detaching from the collar or from the harness. In some embodiments, the loop structure of the anchor may be variable (i.e., adjustable) in size. In some embodiments, at least portions of loop structure of the anchor may elastic.
