Since finding your balls in Fideaux several years ago, thats ALLLL I BUY for my amazingly strong Skye terrier, , who prefers to run about with the small bone in her mouth and pushing the ball with her nose, slamming it into moms shins. How they are a blessing is that she barks whenever folks walk in front of the house, BUT if she has a ball in her mouth they laugh at her instead of being pissed and at least her barks are muffled. In fact i need to order 2 more, cause ALWAYS NEED A SURPRISE when we cant find any of the old ones and they MUST BE [ S.F.]GIANTS ORANGE,, not nearly as interested in the other colours whoever found this strong product is a Saint. the ONLY TOYS SHE TAKES A FEW MONTHS TO DESTROY
