Hi- I did a search for this but couldn't find much on it. My dog has been switched over to a new ford (from Purina One Senior to Wellness Senior). It transition has been very slow, about 2 months. She has been on 100% Wellness for the last 4 days. He stool comes out in two stages, pretty solid/firm in the beginning and ends with wet mess, similar to pancake batter. What does this mean? Should I be concerned? She is happy otherwise, energetic, playful, etc. I will be switching her again, this time to Orijen, not sure if I should wait till this matter clears up or just go ahead and switch now.
