Lennox O Ring Leather Dog Collars are designed with distinct style and functionality in mind. The O Ring minimizes tangles and allows for easier management of your dog by leashing in from the top! Our leather dog collars come in 5 distinct styles and sizes. We created the Lennox O Ring Leather Dog collar so that dog owners would be able to enjoy walking, running, hiking, snowshoeing or other outdoor activities with style and function. Our collars come with a money back guarantee and can be purchased online or at selected boutique pet stores.
