We live with a stoopid woofie who keeps eating our catnip mice. How do we stop it?

I hate to admit, I do not know. When I had Hank the Dog I had visions of gluing his teeth together or covering some of my toys with stuff that dogs would hate and then make him think all my toys were like that, but then I might forget and lick one on accident... it was either tick the people off by ruining his teeth or risking getting a bad taste in my mouth. The only solution may be to hide your stuff. I wish I had better news.
