I would really rather supervise Jasper when he's chewing on stuff, but I feel bad when he's in his crate for a few hours with nothing to do. I was wondering if anyone knows of some safe chewy treats to leave to entertain him with him while I'm gone. I'm so paranoid about him choking on things when I'm not there. He's not really an aggressive chewer though, so I guess that's one less thing to worry about. I was thinking about starting to leave him a bully stick or something. Any suggestions?
