Mick is home and has spoken to the vet (the same one I spoke to yesterday who has been dealing with Millie) and he seemed a little more positive today.
She is in good spirits and is happy to go out and play in the yard. He said that, in theory, although the osophagus has narrowed it is still wide enough to let food through as he got the camera through without a problem. Therefore they just need to try to work out why she isn't keeping the food down and so is hoping that completely resting her throat and stomach will help ease the problem. She is drinking water and is on a barrage of drugs to help. In another 36 hours or so they will try her on a soup like meal and will gradually increase the thickness to see what point she can get to.
He said that it is possible to put a stent down her throat that should help the osophagus widen - if they feel that is needed - but they wouldn't want to do that for a while yet as it needs to heal as there is a chance that if they did it now it could rip.
However, if she still can't keep food down in a few days time he really doesn't see anywhere else to go.
I don't actually think the situation has changed since I spoke to him yesterday - I think it is more to do with the way he has worded it and the way we have interpreted it!
So, still no news yet.
