Buster is now at the vets having his ultrasound plus other investigations. He was no better this morning, he just wants to sleep. He went for a wee at 3 this morning then didnt go for another until we were at the vets. The vet said she may have to ring Cambridge university where he was in February & go on a highr dose of drug for AIHA even though his pcv is ok it could be affecting his pancreas. He looks so sad, it breaks your heart. Will let you know anything when the vet rings but thanks for everyones support.
