Petedge has a Dental Dinosaurs (durable) that I promise, your dog cannot destroy. I bought one a couple years ago when Zada was teething and my sons BIG dog who destroyed everything my son ever bought for him, loved that thing and could not tear it up. I gave it to him to take home and each Christmas I get him a new one. He carries it with him everwhere he goes and chews on it all the time. They are only $3.99.
