so sorry
what a rough day
I would not force feed as she needs to rest her tummy. Dogs can go 5-7 days with no food when older and not a concern of hypoglycemia. Water is most important to stay hydrated and diarrhea is much more dehydrating than vomitting.
She will tell you when she is hungry again as dex will start barking at me when he wants food after I rest his tummy so I never force him to eat if he gets an upset tummy I just let him rest and make sure he gets water.
Hang in there and hopefully just an upset tummy
