My pup Ace is a 1 1/2 year old lab/husky/rottie mix. To say he likes to chew would be an understatement. He won’t play will stuffed dog toys like our previous dogs would, all he wants to do is destroy them! So I got him the super chewer box. He did manage to destroy several toys from that box rather quickly, but they sent us a replacement right away. Now Ace receives strictly Nylon only toys, plus of course the treats. He opens his own box when it comes (after I take the tags off the toys and take the treats out) and he rips apart the box and grabs the toys quick. The toys keep him content so he’s not always trying to chew other stuff around the house. He’s happy and I’m happy.
