I listed my suggestions for durable toys in post #5. I tried to do a copy & paste but then none of the links worked. So, I thought I would just link the whole thread. There are other great suggestions in the thread too.
Hope you find something that helps. Mine will play with a toy for months and then suddenly shred it. I never know what sets them off. Actually I think Ben is the only one who destroys toys. Rocky prefers to chew up my flip flops
