An antique wide leather dog collar featuring heavy metal studding and conical spikes. The collar is constructed from thick, dark leather and is embellished with multiple rows of small, rounded metal studs flanking a central row of large, tapered metal spikes. It is equipped with a substantial metal buckle and a large D-ring for leash attachment. This style of collar was typically utilized for large or working dogs during the late 19th and early 20th centuries. The leather is heavy-gauge and hand-stitched around the hardware. No maker's marks, manufacturer stamps, or patent dates are visible on the leather or metal components.
