Our mutt has destroyed almost every toy we've ever given him, even the ones labelled as indestructible. We got him the medium chuckit erratic balls and he's not destroyed them at all, he likes to play with them on his own too which is a bonus. As they are so bouncy he can just drop it and watch it bounce away, then dives after it and the game starts all over again. Most definitely a 5 star toy!
