Take her to an emergency clinic immediately!
This is a veterinary medical emergency, but hopefully it can be corrected with essential veterinary care.
She has pyometra (uterine infection) and may need immediate surgery to remove her infected uterus. She will also probably need to be hospitalized for several days to correct her blood work abnormalities, to give IV medications and more.
I was very worried about your pug. Please tell me if you have taken her to the vet?
