Hevea's Star shaped activity toy is made from non-toxic natural rubber. It is designed with a hole in the middle to fill with a treat, helping to combat boredom and keep your dog occupied if they suffer from separation anxiety. 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 indestructible! The Star toy also has a textured surface, making it helpful for teething puppies. 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.
