Waterproof, stain resistant, odor resistant, and long lasting. Pet necklaces don't pull on your dogs fur, don't smell or stain like traditional cloth collars, look super cute, and are comfortable for your dog. Enjoy this simple, clean, and minimalistic look! While durable and made with high quality materials, please note that this is a decorative necklace for your pet and we do not recommend clipping a leash to it for the purpose of walking your dog.
