Mare in heat in December???

My mare is a 4 year old Paint (1/2 Thoroughbred) who in the least to say is quite a handful. It seems like she is always in heat. About every 2 weeks she is in heat for 7-9 days. And boy does she show it. I am the only one who can really handle or interact with her during this time, and she is just horrible, but yet I would trust my life to her (yeah I know, but we have this super special bond). Anyhow. My sister-in-law told me during the summer to keep a log of all of her 'marish' behaviour, and when it happens.

I live in Manitoba (and yes, it is being quite unseasonably warm, only about -5 to -15 degrees celcuis). She lives outside 24/7, except for her large run in shelter which I can lock her in, kind of like a stall.

I thought horses usually dont go in heat during the winter months. She hasnt been in heat for a month (or about 3 1/2 weeks) but today she had the start of her heat again. Has anyone else ever experienced this before? Any help would be great! Thanks!

She could be producing extra hormones which is making her go into heat. I would ask the vet the next time they come for a yearly check up/ vacines, or you could give them a call and see what they think. (Calls are free :)

Horses are scared of two things... Things that move and things that don't.

Is there a stud in the area? My friend's mare would go into season every two weeks when she could smell a stud. Boarded at a stables with studs on the facility for about a year, it was like the never ending heat cycles. Though she never got witchy, just obviously in season and drove my gelding crazy. (He wanted nothing to do with her and she was all over him) Then moved to a different stables with no studs, and she hasn't gone into season since.

Want to know the story? From The Start? It is a work in progress.

My mares haven't cycled in forever.
Yesterday, my stallion came home. I have three in raging heat right now that are driving him (and me!) absoulutely batty.

My horse is kept on my family's property (a dairy farm) and has a nice 5 acre pasture all to herself. The only animals near her are cows and wild animals. There are no studs around my area for at least 30 miles.

My mare is on her lonesome with no males of any sort around as well but she still goes into heat regularly. During the winter her heats are less obvious but they're still there.

I wouldn't worry about it too much... :)

Thelma has silent heats, so I got the barest glimps of her heat this spring and nothing since.
Deja was a differant story. She was in hussy mode every few months. Poor thing. She had been bred every year since she was two until she came to me, so her body was all "WTF"?

It has been unseasonably warm in Pennsylvania, with temps near 55^F for five days. It brought many mares back into heat, not just mine.

Mares cycle on light - not temperature.
