All our Good Karma Rope Toys are hand tied and dyed using non-toxic vegetable dyes. As your dog chews, our rope toys fray and act like doggie dental floss. And at Jax & Bones, we believe in playing it forward, so with every purchase of a Good Karma toy, we donate 10% of the proceeds to rescue and animal welfare groups to help these animals find a forever home. Special Features: - Non-Toxic Ropes - Great for Dental Hygiene - Handmade Product Material: Rope
