Glad to hear that his op went ok - Since Hurley's operation I've got to keep him on restricted exercise for 3 weeks and I totally understand how difficult it will be for you, COL'ers have been great at suggesting how to keep him otherwise occupied - I would suggest Kongs, Kongs, and more Kongs, Hurley is also on a BARF diet so I have been told to give him bones which will keep him busy and also tire him out!
