Thank you for thinking of her! She was still a little quiet still this morning but moving much more freely and clearly resigned to the fact that the collar isn't coming off!
The combination of milk, oil, fish and veg has worked a treat today and things are moving much more comfortably in the bowel department!
She is a different dog this evening! We've just been out for a 10-15 minute walk - the tail was wagging happily the whole way and she kind of looked at me as I opened the front door as if to say 'is that all?'!
I can see that by tomorrow the problem isn't going to be us feeling sorry for her, but more about keeping her from overdoing things!!

What is the maximum she should be out walking for? (on lead, of course...)
Thanks for all your support and kind words.
