we're still suffering with this we've got holes int the walls from his chewing and our couch arms are a mess =/ try bully sticks, some member really like them, Pann didn't care for them. Instead I give Pann pig ears and
hooves to avert his chewing and it has helped a
tremendous amount especially the hooves, they last forever and they're cheap and hard and an awesome chew toy. I've also heard bitter spray helps. For us nothing but the hooves and ears worked. good luck!
