Hi! Ok, so today, as my mom and I put the horses back after riding, Tiara went right over and peed, then started winking. Nothing uncommon, but she did the same thing on February first, 6 days ago. And now that I look back, it seems that nearly every time she peed, she would wink like she was in heat. How often do mares go into heat, and for how long? I remember hearing somewhere that constant heat signs are signs of ovarian cysts, but what exactly are they and what do they do, and what treatment is required? And do some mares just act like they are in heat all the time? The only other horse around here is Troya, our 24 year old mare. The nearest other horse is about a mile away. Also, we are going to be breeding her in the spring, so if she did end up having this, would that affect it at all? I really know nothing about these, so please, any information you have. For once, Google is not helping!
