I have a maiden mare in foal that I am not sure when she was bred. I know she is close and was hoping for some help in this department. The last mare I bred I had a foaling date so that helped narrow it down but this was a surprise. We live in a very rural area and have a lot of preditors so I have been waking up every couple of hours and keeping a close eye on her. Last night she was laying down breathing very heavy... tummy was rock hard... and her vuvla was very swollen. I am attaching photos I took today and would love any and all suggestions and help.
