Can mare come in heat off season?

Mares usually come into heat during their breeding season, which typically lasts from spring to fall. However, it is possible for a mare to come into heat off-season, especially if they are exposed to a stallion or if they have a hormonal imbalance. Additionally, some mares may experience a false heat or anestrus, which can cause them to show signs of heat outside of their normal breeding season. If you are concerned about your mare coming into heat off-season, it is best to consult with your veterinarian.
