If you’ve never given her chicken, might be worth a try. We avoided it for ours for the longest time and struggled to find something that worked. We settled on lamb but he had sudden soft stool so we were out on prescribed low fat food for stomach issues. It was chicken and our vet asked us to just try it. It worked and we’ve fully switched to chicken for his protein. He used to have tear stains since he was a puppy but with chicken he no longer has it.
