I’m dog sitting a few times a week (same dog), and he loves chewing up cardboard. He doesn’t eat it or anything, just makes a huge mess. He has nylabones and similar chew toys, but he’s not very interested in them. He seems to prefer things he can rip to shreds easily. Any idea what sorts of toys would be a good alternative to cardboard for him to reduce the mess?
One of our dogs loves to shred cardboard and egg cartons, like you describe. He also really likes toys like this, and will spend time carefully rooting out the smaller toys from inside. As long as we don’t leave the small toys out for too long, he seems content to play with them as they are designed and not destroy them.
