The Hevea Moon activity ball made from non-toxic pure natural rubber. The ball has an uneven surface which makes it change direction - ideal for playful puppies and dogs. Designed with a hole makes both the chewing experience more comforting but you can also tuck in treats to keep your dog entertained. The natural rubber is strong, durable and long lasting yet malleable which makes it perfect for dogs that would usually destroy toys in a matter of minutes as it's chewable but practically indestructable! As dogs are colourblind, one of the colours they see best is orange, which is why Hevea have left this product just as nature made it.
