I had this issue with my frenchie female. She had extremely loose stools I tried chicken and rice and was actually the worst for her ironically. After making sure there was no medical cause,(actual food allergy worms parasites all those factors) I had no choice to put her on the vet prescription diet dry food which worked amazing she was on it and thrived no issues i would occasionally try to switch her and it wouldn’t work. after speaking with different vets for another opinion since she was healthy and doing well there was no reason to change it just made her stool loose again she for what ever reason just had a sensitive stomach. So give it time. Ik its not the best food to be on but if it works it works.
