I have just gone through this with my girl, BeBe. We were traveling in our motorhome, and the same thing happened She also had a fever. She did have a fever. the first vet (Myrtle Beach, Banfields, Petsmart) I think gave her too much predisone for too long. She came right out of her dizziness, but a week later we were in Jacksonville, FL and she vomited digested blood and it was in her stool. The second ver, also Banfields at Petsmart, put her on IV's for 2 days and I am weaning her off prednisone, and giving her meds twice a day. She is almost back to her normal self but lost lots of weight. It was scary for us since we had little choice about where to go, but beware of prednisone!! I am hoping she is on the mend now.
