Wait until you throw one of these new Ballz for Fido! Bounce, fetch, fun - we've done it all. Tails will be wagging uncontrollably and excitement will be high. Just choose your favourite colour. Molecule Balls are soft enough not to hurt your dog's teeth but firm enough to bounce. The Molecule is made from 100% polyester with thick, natural rubber and calcium carbonate that is non-toxic to humans and dogs and floats nicely on water for easy fetching.
