My friend has 2 mares that alway show to a stallion while pregnant, none of my mares have ever done this. We are wondering how common is it for a mare to show heat, while pregnant, and does the breed of the horse make any difference, meaning are some breeds known for doing this more often?
About 10% of pregnant mares will display estrus during pregnancy. To the best of my knowledge, there is no breed predisposition.
