I've recently moved my 4yr old gelding to a new yard and he's absolutely destroyed the edges of his stable, anything he can get his teeth around! I'm tearing my hair out, he's always got a haynet which has helped but he's piling on weight and due to other issues i'm hesitant to up his workload just yet. Dentist says it's normal and he'll grow out of it but ideally I need something sooner!

Any ideas for a healthy alternative I can put in with him to help him cope? Thank you :)
