Thanks for using Petco Pet Education Center, formerly Petcoach! I would consider using a different diet. Jacki may be sensitive to that diet. I would recommend you consider any of the Royal canin, Purina or Science Diet puppy foods which would be great options for her. If you ever notice her stools being black, have her evaluated by a veterinarian as sometimes that is seen with gastrointestinal bleeding. Good luck!
