I picked out a toy at PetCo that Dr. Destructo can't destroy! And believe me, he tries 24/7. It comes in several shapes, next I think we'll get the elephant. It is soft soft rubber, with a way loud squeaker, and perfect for catch and chewing. But try as he might, he can't put a dent in it's super tough skin. And the best part is.....HE LOVES IT!
