LARGE indestructible rubber ball for dogs?

I am having no luck locating a BIG rubber ball for my dog. She is an English Bulldog and she has no trouble at all chewing almost ANYTHING to bits. However, I did find one brand that is remarkably durable-"Kong". I bought her a solid rubber Kong ball about the size of a baseball a year ago and she has long lost interest. She is much more interested in large like basket & soccer (she destroys all my daughters ). Anyway, where can I find a soccerball-sized, indestructible rubber ball? It can't have any holes in it because my dog will get her teeth in them and rip it apart. Any dog toy gurus please advise. Thanx alot!
