Sorry your pups are sick. I think I would do nutrical if she doesn't eat. As you know, it doesn't take long for them to have sugar problems. I don't think the nutrical can hurt, someone please correct me if I am wrong. I'd continue to feed and water normally, as long as she is eating and drinking. Make sure she is drinking, vomiting can dehydrate them quickly too.
Pkease keep us posted....I really hope they both feel better soon!
