Handmade in our Toronto workshop, our collars are made from vegetable tanned, chemical free full grain leather. Protect your dog from synthetic and chemically produced materials. All our leather collars use only the highest quality veg tanned (bark tanning, chemical free) full-grain leather and are built to resist wear and tear from being worn daily. The leather will age beautifully with your pet. One solid piece of full grain leather. No bonded leather, period. This results in a collar that minimizes stretch and will never break or crack at the holes. Built to resist wear and tear from being worn daily, the leather will age beautifully with your pet!
