All good karma dog rope toys from Jax & bones are hand-tied and dyed using vegetable dyes. As your dog chews, these toys unravel and act as doggie dental floss! dip these toys in water and freeze to cool down a hot dog or soothe a teether. Why good karma?! a portion of the proceeds from our toys is donated to rescue and animal welfare groups. This toy is durable and great for agressive chewers or multiple dogs who like to tug and play together. .
