I cant find any toy that Abby cant destroy

, even the ones that are guaranteed to foil even the toughest chewer - she decimates in a very short period of time. The only toys she hasnt demolished are the ones she isnt very fond of - eg Kongs, rope pull toys and those very hard rubber things. She loves, and does not destroy, sponge rubber balls (not tennis balls). I have searched for toys made with sponge rubber instead of that awful stuffing and have come up empty handed so far.

Wish I could manufacture some - would probably make my fortune.
Abby likes to gnaw on her Nylon Bone - this keeps her occupied for long periods.
