In June(of this year) I brought my 21 yr. Old QH mare to a private farm to get her bred to their QH stud. We counted down to when she was supposed to go into heat and brought her to the stud's 1 day before she was due to come into heat. She was then placed in a corral next to the stud and was left there for 3-4 days. She did NOT come into a visible heat. So the stud owner just turned his gentle stud in with my mare on the 5th day and she didn't want anything to do with him. He said that nothing happened.... so we waited 5 more day's and she still hadn't went into heat. So we brought her home.. It's been THREE months and she still hasn't come into heat.
What's wrong with her? Is she just done having foals?
COULD she be possibly bred??
