My Thoroughbred mare was palpated at 5 months pregnant on the dot. The vet declared her open. At month 7 she started getting a large belly and is now at month 8 and her belly is growing. She is bigger on the right side. Has anyone had their mare palpated without US and the vet declared her open and then the mare produce a live foal? :-| She has not developed a bag but I have been feeling movement in front of her udders. It could just be her gut movements or muscle movements. Just wanted to see if this is a typical mistake with veterinarians. Feel free to share stories! I promise I will update thread when I find out. If she has a foal I will post a picture!
