[Zeus is Loved]

Our Perseus is a complete and total handful. I am at my wit's end. He chews the wood off furniture, the baseboards, the quarter-round, etc. I bought bitter Apple, and he loves it which makes him chew the wood more. Last week, I was on the phone with Mississippi State University's emergency hospital for over 30 minutes. He had eaten the thick material, foam underneath, and some of the wood off the lid of my quilt bench. Two days later, he ate, literally, one side of a cardboard box from an Amazon delivery. Yesterday, he pulled the top layer off the sheetrock and proceeded to dig and eat the sheetrock out of the wall. He only does this when we are gone. We have tried all suggestions from the trainer, dog psychotherapist at our vet's office, and everything Dr. Google can tell me. Does anyone here have any suggestions? We already know putting him in a pen is the last option (which we do not want to do, as this would devastate his brother, Zeus, as well). As I say a thousand times a day -- mercy, Percy!!! I am attaching pictures of the destruction.
