Drawing inspiration from their pack of 16 rescue dogs, Earthdog has been making eco-friendly, durable hemp goods for dogs for nearly a decade. Everything is handcrafted in Tennessee, USA. Look at their logo closely, and you'll see a three-legged dog...their original logo model Kody! Unlike nylon and other synthetics, hemp softens with wear making these collars extremely comfortable for your dog. Hemp is a plant which produces the strongest of all plant fibers. It naturally repels weeds, requiring no irrigation, pesticides or synthetic fertilizers, which helps reduce water pollution and soil contamination. Hemp fabrics are naturally anti-bacterial, anti-microbial, mildew-free and rot-free.
