What is the strongest, plush chew toy that there is?

I need a chew toy that my pug/beagle mix can not destroy. She is only interested in soft toys (not hard rubber ones) and pulls the stuffing out in minutes! I have heard that tuffies are good but they are not chew toys. Any suggestions for a durable chew toy?|||anything made by hyperproducts. my dog is a very aggressive chewer and destroys all toys EXCEPT ones made by hyperproducts =] best wishes
