If Ellie's throw up and poop are both red, I would be very concerned that it is blood. It's quite serious when a dog is both vomiting and pooping blood, and that shows she is quite ill. She needs immediate vet care, I would consider all her symptoms a medical emergency. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

    Poor Ellie! The animal she ate may have given her an infection, or have previously ingested rat poison (which caused it to be easier to catch). Rat poison prevents blood from clotting normally, so bleeding internally can occur. I recommend having Ellie seen by her vet right away. There are emergency clinics that are open 24 hours/day in most towns/cities. I hope all is well!
