Our 10 year old, 18 pound Splotch was coughing and at first we thought it was hair balls. It wasn't. Today he went to the vet and was diagnosed with bronchitis. They gave us Orbax and also Prednisone. Now, Orbax I understand. It's an antibiotic. But the other stuff is, among other things, an immune suppression drug. It also had some pretty awful side effects listed. I'm wondering if I should just stick with the Orbax and leave the other stuff alone. Anybody had experience with this?
