My mare went through transitional heat during the month of March. We took her to the vet and had a sonogram done. He found several follicles on each ovary but none that looked like they would develop. He told us to wait to breed until her next cycle. She came into a normal heat cycle the month of April from the 14th through the 20th. She was bred on the 15th and every other day until she went out of heat. I started checking her 14 days later to see if she came back into heat which she did on May the 6th. I waited until the 3rd day of heat signs and bred her on the 8th. Today is the day for me to breed her again but she was acting very strange when I took her to see the stallion. Normally when in heat she is very excited, makes noises and talks to him, will wink, squat, hold tail high and urinate. Today she seemed very interested in him and was talking but when we got up to him she started moving her mouth like a foal would do and lowering her head. She was winking and peeing but her tail was clamped down tight against her rear. I only knew she was winking and peeing when I lifted her tail which was difficult to lift. When I tried to lead her away she didn't want to leave and just kept her head lowered almost to the ground. Finally got her to turn around and she stopped in front of the stallion and raised her tail a bit with more winking. Had to almost drag her away. Two days ago when she was bred she did act a bit strange by kicking out when led away to get cleaned up. (Stallion was already led away and not near her) She is a very easy going mare that has never kicked out like that before and today is the first time she has shown this behavior during teasing. I'm wondering now if she may have taken when bred a few weeks ago and her hormones may be a bit wacky since early in the pregnancy. It was just strange to me that she came back into heat right at the time she should have if she had not taken. I've tried to google search this and have found nothing. Hoping that someone here has had a similar situation. Going to get her to the vet for sonogram but likely won't be able to get in until tomorrow.
The stallion and mare have never had any issues with each other.
Mare is 12 years old.
