A leash-with-variable-anchor has two opposing fastener structures, one for removable attachment to a collar or to a harness and another for fastening back onto a portion of an elongate-member of the leash, forming a 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.
