I have a 1-1/2 yr old female boxer that was recently diagnosed with colitis. We have tried Entro powder and now Tylan powder. They both work pretty good, but there is still blood in her poop sometimes. I was wondering if you could tell me about your dogs experience with the colitis. My biggest issue now is feeding her. Ive been cooking chicken/rice/sweet potato for her and she doesn't get anything else, not even treats. Wny time we try to gradually switch her to dry dog food, the bloody diarrhea returns, so we don't know what to do. Any advice would be very much appreciated. Thank you.
