Captain has started chewing on wood. It is really frustrating, and he gets 24/7 turnout. I have made the decision to send him back home because I have been unable to keep good weight on him despite getting fed twice as many calories a day as he should get. It's been an up-and-down past 7 months, so I think it's time that he be retired fully, and my vet said the same thing. He's just not physically comfortable enough to keep working at upper levels.
