She is in foal. But is a rescue and no one knows when she was covered cause she was most likely covered at the feed lot. I was look at other mare udders on a website and my mares udders look nothing like there ( I was trying to gage about how far along she was) is there something wrong with them or is she doing what she is suppose to do? About how far do you think? Vets are thinking october-december. They didnt do ultrasound because they thought she was to far along and that there would be no point unless they thought something was wrong with the foal.
Her udder will not start changing until she is closer to foaling. I don't think there is anything wrong, she is just not close to foaling.
An ultrasound would be able to measure the foal and give an idea how big the foal is in term to pregnancy development. Course if the vets are thinking October -December that is a minimun of two months and could be 4 months so she still has alot of development left, especially her udder.
