They have ruled a further embolism out, the x rays show the lungs full of fluid as her restricted tubes aren't allowing her to naturally get rid of the mucus you would expect to find on the lungs. She is on steriods, bronchial-dilators and has just finished antibiotics to clear up any potential infection that might cause further scarring. They have talked about doing a lung biopsy but we have decided against this as it is very aggressive way of getting information only to confirm what they suspect is most likely and frankly in the last 18 months she has had enough done.
She has had a good night and looked bright this morning, at least the steriods have upped her appetite so she tucks into her food with gusto which is one of her pleasures. She is just so reluctant to get up and move about and she wheezes when she does which kills me as she was THE most active dog I have ever known and it upsets me to think what she is thinking and what she remembers being able to do, I suppose it's the case for old dogs as well.
Thanks to everyone for their thoughts and wishes! and I hope that Mil gets out soon. It is crazy what we do for them, but somehow you just can't not - thank goodness for insurance!!
