Welcome to JustAnswer, this is Dr. Christie.
Has the cow recently calved or is she pregnant?
Any discharge from the vulva itself? If so, what does it look like?
Is she eating and drinking normally?
she had a calf last year and she seems to be about seven or eight months pregnant now.
Discharge? Yes; she is discharging; It appears clear, but I'm not absolutely positive that it's clear.
Food habit: She IS eating and drinking normally
However, she looks sad, depressed, and her ears are drooping.
Is she bagging up in her udder?
Can you take her temperature rectally for me with either a digital or mercury thermometer? What is it?
Yes, her udder is getting bigger, if that is what is you mean. I will try to take her temperature tomorrow.
Please do let me know what her temp is!
Do you know her breeding date at all?
I suspect if she is bagging up and her vulva is soft, flexible, and she is having a discharge, that she is likely preparing for calving!! :)
