My dog's diarrhea & vomiting returned after switching to normal food.
I'm sorry to hear that Cleo is not doing well. If she improved on a bland diet (chicken and rice), but the signs have returned on her regular food, then I would be suspicious that the food is the cause of the problems. I would recommend resuming the chicken and rice diet to make sure that the signs again resolve with a bland diet. If that is the case, then I would recommend consulting with your veterinarian for a recommendation for food based on what you were previously feeding (brand and protein source), how large the bag was and how long the bag has been open. It may be that Cleo does not do well on that particular brand or flavor of food, it may be a bad bag, or it may have been open too long and started to spoil. Depending on which of these things is most likely, your vet will be able to give you a recommendation on what to try, but I would recommend sticking with chicken and rice for now to make sure that she is back to normal before you make any other changes.
Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
