Do people use probiotics or any other supplements to help prevent flare-ups? There are times she seems VERY uncomfortable and sometimes she won’t poo for a day. We have cut chicken completely out of her diet a few years ago. She only gets grain-free food/treats mostly for the last 6 years. Pumpkin used to help but doesn’t seem to help anymore. If anyone has advice I am looking for other things to try to help her stomach issues.
