Despite the claims in their adverts, this ball lasted no longer than a generic cheap football from the pound shop (..about 30 minutes) The only difference is that it cost 5x the price. We now have one very pleased-with-himself dog and a pricey toy that looks like a dropped Halloween pumpkin.
No response from the company when contacted.
Avoid if your hound is at all on the 'destructive' side when it comes to toys.
