HELP; 9 yr old chihuahua very ill after pyometra surgery

[PicoKnows]

Hi all, and thanks in advance for taking the time to read this.

My 9 year old chihuahua was diagnosed with pyometra. She was spayed yesterday morning. Doc said surgery went fine, but her body temp was low (94 degrees). Doc gave her a pain shot and sent her home.

The dog was INCREDIBLY incoherent all night. Didn't move. Didn't eat or drink or go to the bathroom.

She woke up thismorning, acting the same way. We took her to the vet, and were told she has a "very serious" infection. The dog's white blood cell count is in the 100,000 range, and her body temp is still at about 94 degrees. The doc gave her 2 antibiotic shots, hydrated her, and gave her an oral antibiotic. She sent us home with 2 shots that we have to administer ourselves.

That was 8 hours ago. The dog still has not left her bed, has no interest in food, and is INCREDIBLY lethargic.

We do not know what to do. We are keeping her warm with warm towels and trying to make her comfortable, but this is agonizing. What can we do? What do you all recommend? Any help would be greatly appreciated.
