Thanks everyone for help I had Karen Beaumont up last night to Snoopy and she thinks he may have the start of laminitis but we have caught it soon, she was shocked when she saw how much I feed him and said it was enough for a week, she said basically his feet were good but she gave him a bit of a trim and also trimmed his frog. She advised to keep him in for 3 days with soaked hay and no food or a little tiny bit of food if it made me feel better, then put him in another field with not much grass (dont know how he will take to this cos he will be able to see others in main field). I am now cutting down on feed for him and for my mare as well just in case. Does anyone know anything about muzzles for grass do they stop him eating altogether or just restrict it.
