Yes, so glad you got her vet care sooner than later! Same thing happened to our dog starting in the middle of the night, By morning she was really seriously ill and lethargic, called vet 8:00 a.m. To TELL them I was bringing her in. They said we did the right thing, she spent hours there treated with IV's and medication to stop the diarrhea and vomiting. Went home with an antibiotic and she was back to normal in 24 hours. They can go downhill very quickly. We never knew what caused it...nothing in the lab work.
