Please note that our Black Hardware is powder coated solid Brass and will wear with heavy and consistent use. If your dog is in lots of dirt,sand,mud etc, I do not recommend choosing black, but if you choose black please note that the wear of the hardware is NOT covered under warranty!
I recommend that your dogs neck measurements be one of the middle measurements, if your dog is in between sizes please inquire about custom sizing!
Medium O Ring Collars are best suited for dogs with a 14-16" neck, with the super heavy BioThane and the O ring it can stiffen the collar slightly, If a Medium is being purchased I personally reccomend the Overlap style.
