This is not your average leather dog collar. For starters, it's made from some of the greatest bridle leather available, from J & E Sedgwick in England. The leather is as hard-wearing as it gets and will last the lifetime of your pet, and then some.
The color and finish is really consistent, and will wear in and patina beautifully over the years. The hardware is solid brass, and available in a variety of colors and finishes.
This particular piece is 3/4" wide, which ideal for medium size dogs but can be wider or narrower depending on your pooch and your preferences.
