She is a sorrel.
No apology necessary, it seems everyone thought I was asking for something harsher, She just is constantly pulling and mouthing even at a stand even times when no ones on her that's why I figured it was possibly learned during her racing career and/or was probably not taught to give at all. She has a few other bad habits also, she's cinchy, she sways and paws and will stand in her corral and toss her head and comp her mouth when she's hungry (which is always especially if she knows your watching her LOL sometime I think she's a cow)or your late feeding.shes not high strung but seem like these have been learned stress relievers for her. But beside all that she is a good horse and good with the kids, just needs to be worked with. She is by no means going to be a reining champion for sure.
I have never seen a snaffle with keys like that it is very interesting I am going to look into it more but I think it may be too much. I like the snaffle with the roller I will look into that more considering the rolling curb pacified her a little this may be a good combination with the snaffle for her. And this will work as a double joint snaffle am I correct?
I think a little pacifying wont hurt her, cause as it stands right now she pays more attention to her mouthing then her cues.takes her a minute to catch up.
thanks guys for the suggestions looks like I have some stuff to look into now I appreciate it and if you think of any others let me know....
