Could be from stress, but I'd be concerned about other things first. Nutro has been associated with illnesses and deaths in many dogs. May want to switch... If she isn't better by morning, then she does need to be seen for meds and/or a bland diet. Have you tried chicken and rice? Are her gums pink and moist?
