Uncontrollable Heat Cycles

I lease a ten year old morgan/quarter horse, arabian mixed mare.She is 14.1hh We just started training her this year. She has never had a foal before.
Sadies is a sweet mare. She listens very well and learns quickly. She is a push button horse in the sence that when you touch her sides with your heal she will trot/canter etc. Sadies has regular head cycles, about every 19 days or so. When she comes into heat she changes completely! In the barn (No males inside the barn at all) on the cross ties, she will swing her rump over to the right. When you brush her, from her shoulder down, she will swing towards you and push you against the wall. She then will squirt. When you push her over she gets more "excited" and squirts more. The more you push the harder she pushes back and the more she enjoys it! As you know, this can be dangerous when you are alone in the barn especially.

When you are riding her its terrible. She is no longer that push button mare. She will purposely stop to get you to sqeeze her with your legs. The harder you squeeze, the more she squirts and enjoys it.

In no way is she nasty when she is in heat. She is just pushy and "lovey."
If she has a foal will this problem get any better? Is there anyway to make her more managable when she is in heat?

Thanks to all who help:)

I'm sure some one here can help you. I've heard that there are different drugs you can use, especially with her being so frequently in season. I've heard of people spaying their mares.....I didn't think people would bother with that, but I guess if it's that bad to deal with, it might be an option.

I've had my arm squished by a mare in season, and a boss nearly got suffocated when the same mare pretty much laid right on her in the cross ties.....

I have heard that rasberry leaves are great for calming down hormones in mares, that or regumate. I have used regumate with pretty good success, but not the leaves, which sound like a better less invasive option to me!

Best of luck!

You might look into having her marbled. They put a marble in the horses uterus and it tricks her body into thinking she is pregnant. Loads cheaper than suppliments and its reversable.

I contemplated doing this to pepper when I first got her as she could be a pill when in heat. We ended up doing a claslick first which made marbling not nessesary.. as she was just gulping air and it was making her pissy.

They do this to performance horses alot. Just a thought.

Try some mare hormonal control supplements. I too have heard that raspberry leaves work really well, I also have heard lots of people raving about Mare Magic which has raspberry leaves.

Thank you so much. All of these are really helpful and will run them by my trainer.

I personally haven't seen any change in my own mare on Mare Magic, but she's quiet in heat anyways so not sure there's much to affect on her. My friend had problems with her mare come spring time, she gave her Regumate and it worked great!! But it's a last resort kinda thing to a lot of ppl. She asked about marbling, but was advised against it. I guess it has been known to wander out of the uterus, fall out or make mares infertile. She decided not to take the chance.
Sorry but your post grossed me out a little (very vivid imagination) lol. Glad I lucked out with my girls.

Regumate is not a long term solution. It is quite bad when used for long periods of time. It stops their heat cycles completely so you only use it during the summer. It is also extremely expensive, about $75 a month.

I use raspberry leaves. They work wonders. Mare magic is one brand but you can just buy bulk dried raspberry leaves from a heath foods store for much cheaper.

I bought one bag of mare magic for $14 and it has lasted almost 3 months, so I don't think I'm giving enough lol since it is supposed to last only 60 days.

With raspberry leaves they will still show they are in heat but they should calm down quite a bit. She may still squirt but not as agressively.

The marble has to be inserted at the end of a heat cycle when the cervix is closing.. and it has to be done by a vet who knows what he's doing, not some joe schmo cattle vet ho thinks he knows what he doing because he has seeded a few cows...

Can a marble fall out? Yes, but the odds are reduced if done by a vet who has successfully done it.

Im Sure that that has been cases of the marble wandering and causing infertility but I'm assuming its pretty rare and probably more infection caused. Like I said this is done to performance/ race horses pretty often- Many times these performance mares go off to be broodmares. People wouldn't have this done if the risk of infertility were that high.

Its not right for everyone nor will it work 100% percent of the time just like other methods, but its worth looking into. AND the biggest thing is its not dangerous to handle (like regumate) and its reversable unlike getting the horse spayed. (which IMO is a rediculous option given the mare is LEASED).

OP you should probably check with the horses owner before considering any option. I for one would not be OK with a leasee just doing god knows what to my horse. Suppliments or otherwise. You need to see what they are comfortable with.

Oooh wow! Just read this. IMO no matter what others have done with their own horses...this horse does not belong to you! I would work on your own riding skills, perhaps with a trainer...in order to be able to handle more "difficult" marish behavior....or find another horse to lease.
