Thanks all, he's not been too bothered by it really. It's stopped him from going around the back of the table to get to the back door (no idea why he has to do that anyway when he can get to it directly across the floor) and he has a little trouble chewing his chew as he can't hold it and chew it so it just rolls away down his cone - and guess who gets looked at to pick up the soggy chew
All good at the vets last night anyway so as long as it continues that way he's back there on Monday night, hopefully to have the staples removed.
