Thank you all for your feedback. For the past two days I have given her boiled chicken, and she is HAPPY. She is feeling better and the vet had started Metro and an antacid in case of ulcer then switched to Amforol after hearing of the suspicion of the food spoiling and change of formula. Dezi started to poop rather than leak. but after switching to Amforol, it started to get runny again but here's where the guessing game comes in, is it the change in meds or the chicken? She doesn't always tolerate people food, Vet said feed chicken till she is stable and recommended the Honest Kitchen (never heard of). It's some powdery food you add water to and she just told me to go online to check it out and see if I would be comfortable with it. I will do that now. I was going to try the Cal natural and decided not to but don't remember why, probably the large kibble. I was torn between them and Canidae, guess I know what I should have done now. The simplicity of the cal nat formula was attractive since she's so sensitive. I am still consdering the eukanuba. There is no black stool so the scare of bleeding is passing. But poor Cassidy, after Mondays spay, she's still hugging the floor and really preoccupied and uncomfortable, everyone says after a couple of days their pups were hard to stop from playing and running around. I don't remember how long it was for Dezi to recover. Thanks everyone for being so great.
