Hello!  I have a 2 1/2 year-old female English.  She was doing well up until mid-March when she began filling with abdominal fluid and acting very strange. I rushed her to an animal emergency center four hours from where I live.  She was there for three days while they biopsies her liver, stomach, and intestines and did numerous blood tests.  She came back with a diagnosis of Irritable Bowel Disease with Protein Enteropathy as a secondary diagnosis.  We are now a few weeks out and she is on high dose Prednisone and a host of other medications.  She has muscle wasting and will go for a little over a week before we have to take her in and have her belly drained.  I am also making her homemade high protein meals.  She is not getting any better and it is breaking my heart.... a local vet, as well as myself, are both not convinced that this is IBD... we both feel it has something to do with her liver.  Has anyone ever experienced something like this??  Any and all suggestions and info are welcome.. I don't know what else to do!!!
