Something is bothering Lucy. She has been weird about anyone touching her mouth, accepting the bit, and she has not liked any pressure on her mouth from the bit. A few nights ago she was being a bit "looky" in the ring when I was trying to get on, so someone offered to hold her for me. As I mounted up, the person pulled down just slightly on the reins. Lucy reacted by violently throwing her head in the air and smacking me square in the nose. I was shocked but it was over as quickly as it began, and the ride went on without any further incident.
Then last night, she was very weird about half-halts. Constant (light) pressure on the bit was ok but when I asked for a half-halt, she flipped her head and got upset. Once again, though, it was over as quickly as it began and she was really good for the rest of the ride, though I was careful to ride off my seat even more than usual so I didn't need to do a lot with her face.
Lauren confirmed that Lucy was also weird about her mouth today, so I decided to call Lucy's dentist, thinking something must be bothering her in her mouth. The dentist spoke to me and as I listed off all of the symptoms, he listened intently. He didn't think it sounded like a tooth issue, because Lucy is eating fine (even hay). He said horses sometimes bite their tongues and maybe she had done that. The solution was to give her a few days off to let anything heal that the bit may be interfering with. Lauren and I decided to give her until Sunday as a little vacation, and if on Sunday she is still exhibiting the same symptoms, the dentist will come and look at her next week.
If this were interfering with her ability to eat properly, I'd call the vet, but I really trust this dentist's judgement and hopefully there is nothing bigger brewing! If she gets worse even with the time off, or starts to not eat normally, I will call the vet.
I don't have very much experience with mouth issues - does anyone have any ideas as to what the issue could be? She doesn't seem sensitive around her cheeks or under her jaw, so I do not think it's an abscess.
