Our heavy duty 2 ply leather dog collar is 1-1/4 inches wide and has dome studs. This leather dog collar tapers to 1 inch at the buckle for easier buckling. Stress points are double-riveted and stitched with heavy nylon thread. This dog collar is available in Colors Black or Burgundy and in sizes 19" 21" 23" 25" 27" MADE IN THE USA! All collars are not sized the same. Our collars are sized from tip to tip. Please use a cloth tape measure to measure your dogs neck. To get the correct collar size add 4 inches to your dogs exact neck measurement. For example a 17 inch neck will need a size 21 dog collar. A 19 inch neck will need a size 23 dog collar.
