Thank you for submitting your question regarding Skye. She may not be tolerating her new diet well and experiencing diarrhea as a result. If the diarrhea continues into tomorrow, she will need to see her veterinarian. Being so young, it is easy for her to become dehydrated. Of course, there are other causes of diarrhea that could have appeared at the same time as the diet change. Her veterinarian may perform fecal testing and will likey prescribe a medication. In the meantime, encourage her to drink plenty of water. I hope this information helps!
