First off, no offence to anyone, but most horses get wolf teeth, not just stallions/geldings, your thinking of those big pointy teeth that I can't think of the name of but don't want to look up, they aren't wolf teeth and are usually in male horses but mares CAN have them. Just wanted ya to know.
Eh, maybe they're called something else, but that's what my vet calls them, so that's what I call them. No offense taken, though, I suppose.
But as far as rooting, I see it in many mares, just seems more common, is she doing it when girthing and such? Maybe it's just a signal typically classified as "mareish"? But annoying as it is I understand the need to correct it, and I have no advice as to what bit because I ride english, but I am trying to educate myself more, because I've met a lot of nice western folk who have offered me their horses. I'm finding I hate the saddle, probably cause it doesn't fit, at least I haven't sat in one that does. ;) Hope this helps, but this is still a bad season, as I feel the spring isn't a very natural horse season, but just marks the begining, if I were a horse I'd want my baby born about a month ago, when it was hotter during the day, to prevent chilling of a newborn foal, and nice at night, when I probably would decide to foal out, so I feel this is really the heat of mating season. January 1 is an easy human date, not neccesarily when horses want to have babies, and TB"S have made an early year foal the norm. Maybe watch for signs of the season and if you feel it corresponds, hormones might be the best option.
If I understood you right... you thought it was her acting out because of breeding season? I don't breed horses, so I can't say for sure that mares act differently during a particular time of year or not, but I've never noticed any of my mares acting up at one particular time of year (except during their "mare days"
). Magic's just done this for as long as I can remember, and only while we are standing still (which is what has made me think it's a boredom thing).
And it does appear you have an infamous chestnut mare, but again, I'm to lazy to research, but have always had good terms with those particular horses, and believe me I remember all of them! Each was quirky in it's own way.
Um, not really sure what you mean. ^^;
If you keep her on a shorter rein, that can be causing her rooting. You may try to put her in a milder bit just for a while and work on a looser rein than she is used to. I see the rooting alot in horses ridden on tight reins all the time. If her mouth is that sensitive, she may respond better with just a regular snaffle instead of a shanked bit. I don't really care for the broken mouth shanked bits unless the rider has VERY soft hands. An option for a shanked bit is a solid mouth ported bit with very short swivel shanks. I use this on my horses and they respond very well. Plus, it does allow for direct reining without being confusing. Plus you have the loops to make it more like a snaffle instead of a curb if you choose.
I usually try to keep her on the loosest rein I can manage, because she gets upset and less-responsive on a short rein... I ride with ~8ft split reins (despite the gaming
), and outside of showing, I'll sometimes just tie the ends together and drop them over the horn, and she'll keep right on rooting.
Other than a bit of a tug for 'whoa' or backing and the bit of direct reining to get her around a barrel, I rarely even have to use anything but neck reining and leg pressure. Any direct reining I do with her is really light... Almost just picking up the left rein to go left, and there's barely any pressure to it. She's definitely the lightest horse I've dealt with, but I've adapted pretty quickly to how she'd rather be handled, so I believe I'm pretty light handed. Besides me, no one else rides her, either.
