Poor Bailey! Cat food is often tasty to dogs but unfortunately it is hard on their GI tracts. Puppies especially do not tolerate rapid diet changes, which can lead to bacterial imbalance in the intestines and diarrhea with blood. Because Bailey is still a young puppy, the diarrhea could also be caused by an intestinal parasite. It's a good idea to bring her into the vet so they can perform a fecal test and prescribe anti-diarrhea medication as needed. You can feed her a bland diet of white rice and boiled low-fat chicken breast to try to settle her stomach in the meantime. I hope she feels better soon!
