My mare has recently begun grinding her teeth more and more, it originally started out as a once in awhile thing, mostly when we were having a bad ride and I was being nervous and she was getting aggravated... but now it's an every single ride thing, she even does it when my trainer rides her in her once a week training rides. I thought it was a sign of her being aggravated, but now she's doing it even during perfectly wonderful rides, I'm confident and happy, she's happy, ears pricked, yaddie yadda, but she grinds her teeth the whole time, and its getting louder too!
Nothing in her tack has changed in the last 8 months, I got a new saddle back in july (that was fit to her) and she's had the same type of bit for the last 3 years no problems.
The vets coming out tomorrow to check her teeth, check for ulcers, or anything else pain wise that may be causing it.
But I thought I would post and see if anyone on here has any suggestions for what might be causing, and what may have caused it to get so much worse in the last couple of weeks!
