Our 1 1/2 yr old white male boxer named Dexter has recently been diagnosed with ulcerative colitis. Quite possibly Histiocytic colitis. He just started baytril 138 mg once a day and metronidazole 750 mg per day. Any one here have any experience with this disease and the treatment for it? What was the outcome? He is the sweetest dog and we are so worried. Any info would be greatly appreciated. thanks, kim...
