My first yorkie was diagnosed with collitis shortly before she turned 2. Vet put her on meds and we put her on a presciption food (been so long ago, can't remember the name) for a short while. I didn't change her food (other than the presciption food for a few days) because I felt it might do more harm than good to switch. Whenever her collitis flared up, I would boil chicken for her and mix it with rice and/or scrambled eggs - bland food for a few days to help settler her back down.
Like others have said, I wouldn't switch foods as it may make things worse. Best of luck to you!
