Watery diarrhea is concerning, because this can cause her to quickly become dehydrated. If it was due to the Simparica, then it would expected to be resolved within a day or two. If the diarrhea last longer than that, or Freyja is acting very lethargic, starts having tremors, or having bloody diarrhea, then it's best to take her to the vet as soon as possible for treatment. For now, it will be good to add oral rehydration salts, or Pedialyte to her water in order to keep her hydrated. Below is a link to an article with more helpful information. https://mobile.petcoach.co/amp/article/diarrhea-vomiting-in-dogs-when-to-call-your-veterinarian I hope that helps and Freyja gets better soon.
