I was lunging my mare this morning when a friend standing by the fence heard her teeth or jaws banging (hard to explain) together when trotting..this must be hurtful or terribly anoying ...I've never noticed as I thought the noise was from her hoof booties..her teeth were filed 4 months ago because she couldn't chew her hay properly and vet said she had ulcers from her teeth being neglected for years (we just purchased her in Dec) now wondering what this could be ? :roll:
