The hubby and I went to the specialty pet store yesterday and bought a new toy for our boy. It is apparently rated a 9 out of 10 on toughness level. It claimed to be made of 4 layers including hard plastic, 2 layers of "luggage grade" material, and soft fleece. It is such a hard toy I could probably club a human with it. It lasted less than 24 hours. I just confiscated it from poor Gunther because he ripped open an end and was eating the threads and stuffing. I have yet to find a truly indestructible toy for our almost 9 month old. My next step is the tractor supply store to get him some tires. He loves tires.
